Subject: Soft drinks. Classification

Beer is a group of low-alcohol grain-based drinks that are made by fermentation without distillation. Three types of beer are produced in Russia: light, semi-dark and dark.

Light beer has a color from 0.4 to 1.5, semi-dark - 1.6-3.5 and dark - 3.6 and more than 2 centners. units (the color unit corresponds to the color of a solution consisting of 100 cm 3 of water and 1 cm 3 of a solution of iodine with a concentration of 0.1 mol / dm 3).

For production, use light or medium color malt, semi-dark? light or caramel, dark - dark or caramel, or burnt.

Depending on the extract content of the initial wort, light beer is divided into 16 groups: 8, 9, 10, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22 and 23%, semi-dark and dark - at 13: 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22 and 23%.

In addition to the above groups, a special 12% beer is distinguished into a separate group, which is produced in two types: semi-dark and dark. Semi-dark beer does not contain alcohol (non-alcoholic beer), and dark beer is distinguished by a reduced volume fraction of ethyl alcohol (no more than 3.2%) and color (1.9-3.1 centner units).

Beer groups differ in the initial density of the wort, which is determined by the content of extractives in the malt-hop wort before it is fermented by yeast. During the period of fermentation and post-fermentation, the sugars of the wort are fermented into ethyl alcohol and other compounds. There is a direct relationship between the extract of the initial wort and the alcohol content in beer. With an increase in the extractivity of the initial wort by 1%, the volume fraction of alcohol in light and semi-dark beer increases by 0.2-0.8%, and in dark beer - by 0.1-1.1%. Beer with an initial wort extract of up to 5% has a low alcohol content, up to 12% - medium, over 14% - strong beer. Strong beer contains at least 9.4% alcohol by volume.

According to the processing method, beer is divided into unpasteurized, decolourized and pasteurized. The deflated beer is passed through special filters that neutralize it from microorganisms. Pasteurized beer is obtained by heat treatment.

Original beer - light with an extended maturation period and increased rate hops (for example, "Baltika No. 4").

Special beer is made with the use of flavoring and aromatic additives (for example, "Siberian Crown Lime" with the addition of lemon flavor).

About 90% of the beer produced is light varieties. Typical light beers include: Zhigulevskoye, Baltika No. 0 (non-alcoholic), 1, 2, 5, 6, 8 (wheat unfiltered), Admiralteyskoye, Klinskoye light, Tolstyak, Rossiyskoye , "Anniversary", "Honey", etc.; to semi-dark: "Ochakovo" semi-dark, "Athanasius" semi-dark, "Athanasius" Kind semi-dark.

Among dark varieties beers are best known: "Baltika" dark, "Porter", "March", "Velvet", "Tver" dark, etc.

"Zhigulevskoe" beer is a drink with a characteristic full taste with mild hop bitterness and light hop aroma. Extractivity 11%, volume fraction of alcohol 4%.

"Athanasius" Good semi-dark - copper color, with a slight caramel flavor. Made using caramel malt. Extractivity 12%, volume fraction of alcohol 4.3%.

"Athanasius" dark - strong beer of dark color with a ruby ​​hue, sweetish taste with moderate hop bitterness, aroma with a touch of caramel malt. Extractivity 15.5%, volume fraction of alcohol 5%.

Currently, new varieties of beer have been developed and introduced, which differ in a set of grain raw materials, technological regimes, the use of non-traditional additives (wormwood, yarrow, leuzea roots, pink radiola, pine nuts, etc.). Their recipe is the property of the enterprise, information about them is classified.

The range of beer on the Russian market is represented by over 150 names. About 30% of beer is accounted for by well-known brands: Ochakovo, Yarpivo, Klinskoye, Old Miller”,“ Fat Man ”,“ Athanasius ”, etc.

Low-alcohol beer contains no more than 1.5% alcohol by volume. (in some countries 1.5-2.5%), non-alcoholic - up to 0.5% vol. In Russia, low-alcohol beer "Table" is produced with an initial wort extract of 8% and alcohol of 1.5% vol.

The range of cocktails produced in Russia and abroad is very extensive and reaches several hundred items due to the use of diverse components and recipes.

Names of cocktails sold on the Russian market:

Vodka-based cocktails - "Helicopter" with modifications - Banana, Pineapple, Cherry + Pineapple, Mango, Orange (using food additives); " Bloody Mary" (With tomato juice); "Screwdriver" (with orange juice); "Hoppy Cowberry", "Hoppy Cherry", "Hoppy Red Rowan", "Hmelnaya chokeberry"," Intoxicated lemon "; "Bravo" (with food additives imitating pineapple, cranberries, gin and tonic); "Eva", "Ekaterina", "Roulette", etc.

Wine-based cocktails - Vintage White, Vintage Red, Vintage Pink (natural wine + ethyl alcohol, caffeine + flavors + lemon and orange extracts), Bianco (based on vermouth), Screwdriver (vermouth + orange juice), Cider special Ochakovsky.

An analysis of the range of low-alcohol cocktails on the domestic market shows that the largest share (about 90%) is occupied by drinks prepared on the basis of vodka or ethyl alcohol. Among these types, the proportion of drinks with artificial or synthetic food additives is quite high, including cocktails such as Gin and tonic. Cocktails are represented by certain brands with modifications, for example, brands such as Helicopter, Screwdriver, etc.

The range of mineral waters is represented by a significant number of names, which most often coincide with the name of the place of origin. A fairly large amount of mineral water comes from the CIS countries, especially from Georgia (for example, Borjomi-type drinks: Borjomi, Nabeglavi, Bajoti).

Of the medicinal table mineral waters, the most common are such names as Borjomi, Essentuki No. 4 and No. 17, Hot Key No. 1, Narzan dolomite and sulfate, Polyustrovo, Marcial, Smirnovskaya, Slavyanovskaya, etc .; from medical - Bjni, Jermuk, Avadkhara, Buyskaya, Nelepinskaya, Lower Karmadon, Naftusya, Sakhalinskaya, Elbrus.

The name of one-component carbonated drinks coincides with the specific name of the juices, syrups or extracts used: Apple, Pear, Grape, Cherry, Pomegranate, Cranberry on the juice, Cranberry on the juice, etc. Multi-component drinks include Little Red Riding Hood, Summer, Children's, Pinocchio, Duchess, etc.

The range of spicy aromatic drinks is represented by domestic brands: Sayany, Baikal, Tarragon, Bakhmoro tonic, as well as foreign ones: Bitter and amateur tonic, Sprite, Schweppes, etc.

Kvass drinks - drinks made on the basis of a concentrate kvass wort, grain raw materials with the addition of various components. The content of kvass wort concentrate or extract of grain raw materials must be at least 2% of the total volume. The use of artificial sweeteners (sweeteners), artificial flavors and artificial colors is not allowed. Assortment: "Vintage", "Rye", "Traditional", etc.

Soft drinks are drinks that do not contain alcohol or contain it in minimum quantities(up to 0.5%) and intended mainly to quench thirst.

At the same time, a number of drinks have a fairly high biological, physiological and energy value. Many of them include sugars and other substances that come with juices, concentrates, extracts, infusions, etc. Drinks on a natural basis contain vitamins, mineral elements, organic acids, coloring, aromatic and other compounds. Kvass, drinks made from grain raw materials, as well as functional drinks, the market of which is growing at a faster pace, have a high nutritional value.

The classification of soft drinks is multifaceted and has its own characteristics in different markets.

According to the raw materials used and production technology, drinks can be divided into the following groups: drinking water; mineral water; juice drinks; drinks on grain raw materials; drinks on spicy-aromatic vegetable raw materials; flavored drinks (essences, aromatic alcohols); drinks on concentrates; fermented drinks.

According to the degree of saturation with carbon dioxide, liquid drinks are divided into highly carbonated, medium carbonated, slightly carbonated, non-carbonated.

According to the method of processing, drinks are pasteurized; unpasteurized; with the use of preservatives; without the use of preservatives; cold drinks; hot drinks; aseptic drinks.

Mineral waters include waters containing in their composition (in dissolved form) more than 1 g / l of mineral salts.

Depending on the method of production, mineral waters can be natural (natural) or artificial, non-carbonated and carbonated (naturally or artificially).

All types of waters can be additionally aromatized.

According to the degree of mineralization, mineral waters are divided into table (up to 1 g / l of salts), medical table (1-10 g / l) and medicinal (over 10 g / l). In trade, only the first two groups are realized, since drinking medicinal waters are used only by special prescription of a doctor. The latter also includes waters of lower mineralization, but containing in their composition an increased amount of some biologically active components (iron, arsenic, orom, iodine, lithium, radon, etc.).

Depending on the chemical composition of salts, mineral waters are divided into chloride, sulfate, hydrocarbonate, complex composition, etc. (more than 60 groups). The predominance of certain salts and gases determines the organoleptic characteristics of waters. So, the presence of carbon dioxide gives a sour taste, sodium salts - salty, sulfate - bitter, ferrous - astringent, sulfuric - an unpleasant smell and taste.

Except traditional way for obtaining mineral waters from underground sources, there are methods for their production by dissolving in drinking water a dry concentrated residue or liquid concentrates (brines) of natural mineral waters at the places of their bottling.

Artificial mineral waters are aqueous solutions of various salts saturated with carbon dioxide.

The use of brand names of world famous natural waters (Borjomi, Essentuki, Narzan, etc.) for artificial salt solutions is a gross falsification.

The group of drinking water includes both natural (artesian) and specially treated other water with a total mineralization of up to 1 g / dm 3 that meets all sanitary-hygienic, organoleptic and physico-chemical requirements. The deterioration of the environmental situation in the world determined the intensive growth of this segment of the beverage market in the world (up to 20% per year). In the US and Japan, drinking water consumption has already reached 150 liters per capita per year. Obtaining a high-quality drinking fashion is carried out using ozonation, UV filtration, reverse osmosis, ultra- and nanofiltration, as a result of which microorganisms and most organic and inorganic impurities are removed from it. In the future, water can be mineralized to physiologically optimal values, be carbonated, enriched with vitamins, microelements (iodine, fluorine, etc.), and aromatized.

Non-carbonated soft drinks, this group includes fruit, berry, vegetable and other juices, as well as concentrated drinks (syrups, extracts).

Juices are obtained by processing fresh benign fruits, berries and vegetables, as well as from some woody plants (birch, maple). Juices not only quench thirst well, but also have a fairly high biological and physiological value, determined by the content in their composition of vitamins, mineral elements, easily digestible sugars, organic acids, essential amino acids, pectin and other substances.

Depending on the method of production and composition, juices can be natural, with additives, concentrated, as well as clarified, translucent and opaque (with pulp). Translucent - these are juices, during the storage of which a precipitate forms. Clarification of juices is carried out by treatment with bleaching clays, tannin, gelatin, followed by filtration. Natural juices (with or without pulp) can be freshly pressed, as well as reconstituted from concentrated natural juices. They do not contain additives, and the amount of soluble solids in them is almost the same as in the fruits from which they are made.

Depending on the feedstock and quality, natural juices are divided into ordinary, vintage and blended. Vintage juices are produced from certain high-quality varieties of fruits and berries, ordinary juices are produced from a mixture of different pomological varieties of the same type of fruits and berries. Blended juices are obtained by adding juices from other types of fruits and berries to the main one.

Concentrated juices include juices in which the moisture content is reduced by at least half compared to the feedstock, and the mass fraction of solids reaches 70%. Modern juice concentration technologies (cryoconcentration, reverse osmosis, etc.) ensure almost complete preservation of the chemical composition and nutritional value of natural freshly squeezed juice. Concentrated juices are not divided into varieties.

Extracts differ in that they are obtained from natural juices clarified and preserved with sulfur dioxide and sorbic acid by evaporation in vacuum apparatuses at a temperature not exceeding 60 ° C to a solids concentration of 44 to 62%. For the production of extracts, only transparent fruit and berry juices with minimum content pectin substances and a well-pronounced aroma (grape, cranberry, blackcurrant, etc.).

Juices with sugar are produced from fruits and berries with high acidity or low sugar content to improve their organoleptic characteristics. The amount of added sucrose should be no more than 25% or sweeteners in an equivalent amount.

Juices for baby food(natural, vintage, blended, with pulp, fortified, etc.) are prepared only from high-quality fruit and berry raw materials with the establishment of shorter warranty periods of storage.

Nectars include drinks containing at least 25-50% juice or puree (homogenized fruit pulp). To obtain nectar, fruit juice, puree or juice concentrate is mixed with sugar syrup, water, honey. Citric and ascorbic acid are added to the nectars to improve the organoleptic properties and shelf life, and vitamins are added to increase the biological value.

Juices from whole fruits are obtained by grinding them in special mills, followed by homogenization. Drinks based on these juices are highly turbid, high-viscosity, with a large sediment and a peculiar taste.

Currently, juice concentrates (compounds) based on natural concentrated fruit and berry juices or their mixtures with various ingredients are in high demand on the world market. Concentrates with high consumer properties are obtained by cryoconcentration (freezing at -30-40 °C). In addition to deep-frozen concentrates intended for the production of natural juices at the point of consumption, there are semi-frozen concentrates (at -18 °C) on the market intended for the end consumer. Semi-frozen concentrates do not lose fluidity, are characterized by good reducibility without preliminary thawing and storage without the addition of preservatives.

Carbonated drinks are aqueous solutions of various components of natural and artificial origin, saturated with carbon dioxide and hermetically sealed. By composition, they are divided into many groups: drinks based on natural raw materials, on synthetic essences (flavors), on concentrates, tonic, fortified, special purpose, etc. The market classification of drinks is even wider, it represents a significant number of product segments designed to meet the needs of various target groups (athletes, tourists, miners, the elderly, drinks for the occasion or for a certain time of the day or year, etc.). The group of functional drinks is developing most dynamically (15-20% per year).

A functional drink differs from a normal drink in a special effect in terms of nutritional physiology, which exceeds the effect regular product and may be advertised as an added benefit. According to their purpose, composition and action, they are divided into several groups: healthy, energy, sports, nutraceuticals, pharmaceuticals, neuroceuticals that promote well-being, etc. Modern technologies make it possible to obtain them with a given chemical composition, and the recipes for the branded range of these drinks are selected in in accordance with the specific physiological characteristics of the body of target consumers.

The range of such drinks is expanding due to the introduction of essential nutrients, pre- and probiotics. basis healthy drinks constitute natural ingredients- fruit and vegetable juice, mineral water, milk. Such drinks, enriched with vitamins, minerals, dietary fiber and essential fatty and amino acids, contribute to the normalization blood pressure, prevent cardiovascular, oncological, gastrointestinal diseases, intoxication, etc. This category includes breakfast and lunch drinks, as well as health drinks, whose share on the world market has increased by 44% in recent years. The main function of sports drinks is to maintain and improve the body's performance, compensate for fluid loss during physical exertion. Vitamins, minerals, easily digestible carbohydrates (glucose, fructose) and their decay products (maltodextrins, glycerophosphate, etc.), amino acids are introduced into their composition.

Fermented drinks include kvass and fruit drinks. Bread kvass is an old Russian drink, which is a product of unfinished lactic acid and alcoholic fermentation. Currently, kvass ranks 4th in terms of sales among all soft drinks and is the fastest growing market segment. The raw materials for the production of kvass and drinks from grain raw materials are high-quality rye and barley, malt, concentrated kvass wort or enriched kvass wort concentrate, kvass loaves, citric and lactic acids, hops, caraway seeds, infusions of citrus and aromatic plants, molasses, yeast, sugar color, long leaf tea, etc. Currently, all drinks called "kvass" are divided into three groups. The first group includes kvass proper as fermentation products with yeast. They have a high energy and biological value, and their range is expanding through the use of unhopped beer wort, apple extracts, juices, whey concentrate, potato processing products, glucose-fructose syrups and other food and flavor additives. Another group is formed by mixed kvass drinks based on kvass wort concentrate or other grain raw materials, but without the fermentation process. The third group includes drinks called "kvass", but prepared without the fermentation process and kvass wort concentrate - on flavorings. Information about this is mandatory on the label of drinks.

Introduction

carbonated soft drink

Thirst occurs when the water content in the body decreases by only a liter and a half. To remove the suffering brought by it, it is enough to drink two or three glasses of liquid. The easiest way to make up for the lack of moisture is with ordinary drinking water, but for some reason people prefer the so-called soft drinks. And this is justified. It turns out that it is easier to quench your thirst with a drink than with pure water: the drink contains substances that retain moisture in the body. Mostly soft drinks contain sugars, organic acids and minerals. It is this set of components that helps moisture to linger in the body. Drinks rich in organic acids and potassium salts are especially good in this regard: fruit juices, nectars, berry fruit drinks, water with the addition of lemon juice.

Lemonades were the prototype of modern carbonated drinks. The fashion for them spread in Russia at the end of the 19th century. This wonderful refreshing drink was prepared simply: lemon zest was rubbed with sugar, mixed with lemon juice, diluted with hot water and cooled.

Over time, the lemonade recipe was enriched with cranberry juice, strawberry and raspberry syrup, infusion of apple skins, honey, etc. And later, lemonades learned to carbonate in siphons.

In recent years, the range and production of soft drinks in Russia has grown significantly. In addition, most importing firms supply non-alcoholic beverages with the addition of food additives that are not allowed for consumption by the domestic industry and hide them in the recipe, so there are big problems with the quality of non-alcoholic beverages consumed by the population.

With the replacement of natural syrups and infusions with food colors, flavors and other substitutes, the falsification of carbonated drinks has become easier. Currently, carbonated drinks and mineral water are one of the most counterfeited groups of goods, so the relevance of the topic of the thesis is obvious: at present, there is a very acute problem with conducting a comprehensive examination of the quality of all types of soft drinks entering the Russian market.

The purpose of this thesis is to study the factors that form the quality and examination of the quality of soft drinks on the example of LLC Group of Companies "Bavaria Brewery".

To achieve this goal, the following tasks were solved:

The study of literary sources on this topic and the systematization of the information received;

Study of raw materials and production technology of fruit carbonated drinks;

Development of a methodology for conducting an examination of the quality of fruit carbonated drinks;

Evaluation of the quality of fruit carbonated drinks;

Research of competitiveness and consumer preferences of products of Bavaria Brewery Group LLC

1.Commodity characteristic soft drinks

1.1 Classification and range of soft drinks

Carbonated soft drinks include carbonated water with added syrups sold through the soda network, bottled carbonated drinks and dry carbonated drinks. The basis of the first two is carbonated drinking water. The diversity of the assortment of carbonated drinks is due to the types of auxiliary raw materials, which include fruit and berry juices, syrups and extracts, sugar, sorbitol, fruit drinks, grape wines, tinctures, flavors, food acids, etc.

Soft drinks in appearance are divided into types:

liquid drinks - transparent and turbid;

· Beverage concentrates in consumer packaging.

Depending on the raw materials used, production technology and destination, drinks are divided into groups:

· drinks on grain raw materials;

· drinks on spicy-aromatic vegetable raw materials;

Flavored drinks (essences and aromatic spirits);

fermented drinks;

drinks for special purposes;

artificially mineralized waters.

Liquid drinks according to the degree of saturation of carbon dioxide are divided into types:

highly carbonated;

medium carbonated;

· lightly carbonated;

non-carbonated.

Liquid drinks according to the method of processing are divided into:

unpasteurized;

pasteurized;

Drinks containing preservatives

drinks without the use of preservatives;

cold drinks;

hot drinks.

For the preparation of drinks at home, syrups are produced in consumer containers. Syrups in appearance are divided into transparent and opaque.

Depending on the raw materials used and the purpose, syrups are divided into groups:

Syrups on vegetable raw materials;

Syrups on fruit and berry raw materials;

Syrups based on aromatic raw materials (essences, essential oils, citrus infusions, aromatic additives);

Syrups for special purposes.

According to the processing method, syrups are divided into:

syrups with preservatives;

Syrups without the use of preservatives;

· hot filling syrups;

pasteurized syrups.

Currently, domestic factories and workshops for the production of non-alcoholic products produce:

· non-alcoholic carbonated drinks with low calorie content, as well as for diabetic patients with the use of aspartame, xylitol, sorbitol and other sweeteners. They are classified as special purpose drinks;

carbonated drinks, which are water solutions of sugar saturated with carbon dioxide with the addition of products of processing of fruit and berry raw materials (juices, extracts, etc.), spicy-aromatic, including vegetable (infusions of herbs, roots, citrus peel, etc. .p.) raw materials, aromatic substances (essences, essential oils), dyes, aromatic acids;

Beverages based on grain raw materials, which are solutions of kvass wort concentrate, sucrose saturated with carbon dioxide, food acids and other aromatic and flavoring substances;

fermentation drinks, which include bread kvass, fruit and berry kvass;

· artificially mineralized waters, made from mixtures of salts and saturated with carbon dioxide;

non-carbonated drinks, including dry drinks, effervescent and non-effervescent, made from sugar, tartaric acid, soda, essences, extracts and dyes.

Russian enterprises produce the entire range of drinks and concentrates listed in the classification. The composition of drinks is determined by their recipe. It is accompanied by data on the characteristics of physico-chemical and organoleptic indicators, food and energy value drink.

In the all-union "Collection of recipes for non-alcoholic drinks" according to GOST 28188-89 "Non-alcoholic drinks. General technical conditions "there are 115 recipes for non-alcoholic carbonated drinks,

14 - for non-alcoholic non-carbonated drinks, 16 - for kvass and drinks made from grain raw materials, 3 - for powdered concentrates of soft drinks.

In addition, there is a collection of recipes for national species soft drinks, including 60 types of carbonated drinks and 5 - kvass and drinks from grain raw materials.

Technical conditions for new names of drinks are constantly being developed by manufacturing enterprises, institutes of the corresponding profile. The main organization that develops and introduces into the production of recipes and technologies for soft drinks and concentrates in our country is the Scientific and Production Association of the Beer, Non-Alcoholic and Wine Industry.

The main features of modern technology of soft drinks:

1) the use of concentrates of a high degree of readiness;

2) production of low-calorie drinks using sweeteners;

3) increasing the stability of drinks by adding a preservative - sodium benzoate;

4) filling into non-negotiable PET bottles (made of polyethylene terephthalate).

Depending on the name and raw materials used, the mass fraction of solids in drinks ranges from 4.5 to 12.5%, acidity - from 1.25 to 4.8 cm 3 of an alkali solution with a concentration of 1 mol / dm 3 per 100 cm 3 of the drink.

The composition of domestic drinks includes natural species raw materials: processed fruits, berries, infusions, sugar, essential oils, essence. In recent years, the range of domestic products has significantly expanded due to drinks based on imported concentrates from various companies.

Manufacturers and suppliers of traditional domestic drinks turned out to be unprepared for competition. Our drinks are less technologically advanced, more expensive, with a short shelf life, less attractive in appearance.

Soft drinks contain about 90% water, and the export of finished drinks is currently very rare. Foreign firms prefer to supply the Russian market with concentrates and other raw materials for non-alcoholic beverages, and also invest in the construction of plants for bottling beverages based on their concentrates on our territory.

One of the first companies to master our market was PepsiCo Inc., which invested in the construction of Pepsi-Cola bottling plants in Novosibirsk, Novorossiysk and others. Coca Cola”, “Royal Grown Cola Co. International” and others. This led to a change in the structure of production, to an increase in the production of drinks from concentrates and according to the technology of foreign firms, mainly under the trademarks “Pepsi Cola” and “Coca Cola”.

With all the variety of soft drinks on the world market, there are two main groups:

fruit drinks with the aroma and taste of fruits and berries, containing natural products of them;

· Fantasy drinks such as "Cola" with the use of spicy-aromatic raw materials.

In turn, each of these groups includes several subgroups:

· traditional drinks on sugar;

Low-calorie drinks with sweeteners (the so-called diet);

vitaminized drinks;

isotonic or sports drinks containing salts;

Beverages containing ballast substances (fruit pulp, natural thickeners, opacifiers).

A major manufacturer and supplier of concentrates, bases and essences for the European and Russian market- the company "Dehler Glibh", founded 160 years ago. Its parent company is located in Darmstadt (Germany), in addition, the company has 11 subsidiaries in Belgium, the USA and other countries. The company supplies a wide range of ingredients for Cola drinks, lemonades, juice drinks, nectars, fruit juices, cheap soft drinks without juice, for drinks enriched with vitamins, minerals, ballast substances. At NPO PB and VP in Moscow since 1992. operates a representative office of this company.

Drinks based on Deler concentrates are produced by many enterprises, including the largest ones: Rosar OJSC (Omsk), Pikra OJSC (Krasnoyarsk), etc.

A number of other foreign companies also supply raw materials and concentrates to our market: Quest International (Netherlands), Milesto (Yugoslavia), etc.

Among foreign producers of beverages, the company Kajo (Germany) has a significant turnover, producing diet drinks under the brand name "Dayt" based on natural juices, including those with pulp, enriched with a complex of vitamins, instead of sugar they use a mixture of saccharin and cyclamate. Famous drinks of this company - “Give a transparent lemon”, “Give a cloudy lemon”, etc.

Among the major European beverage producers are

Imperial (Great Britain), Cadlewry-Schloeppes (Great Britain), Grand-Metropolitan (Great Britain), BSN Gervais Danon (France).

In terms of the consumption of non-alcoholic beverages in the world, the first place belongs to the United States - more than 160 liters per capita, a high level of consumption in Belgium, Austria, Switzerland, Germany, France - 40-50 liters per capita.

In general, there is a tendency to increase the consumption of ready-made non-alcoholic carbonated drinks, instead of hot and strong ones. The annual increase in the consumption of soft drinks is projected at 3%.

1.2 Factors that shape the quality of fruit sodas

1.2.1 Characteristics of raw materials for the production of fruit carbonated drinks

A wide range of fruit carbonated drinks is defined by a large number of various kinds raw materials that are part of the blend of drinks. Raw materials used for the production of soft drinks must meet the requirements of the current regulatory and technical documentation.

Sugar (sucrose C 12 H 22 O 11) is added to drinks to give them sweetness and soften the sharpness of the sour taste. The addition of sugar also contributes to the assimilation of aromatic substances introduced into drinks, and, consequently, to the formation of their bouquet. Sugar is used in the form of granulated sugar and refined sugar. The amount of added sugar determines nutritional value and the calorie content of the drink. Sugar is sucrose (C 12 H 22 O 11) obtained from sugar beet and cane. Sucrose melts at 160C and caramelizes at higher temperatures. For the preparation of soft drinks, granulated sugar (according to GOST 21), refined sugar (GOST 22) or liquid sugar(OST 18-170). Such sugar consists practically of chemically pure sucrose: from 99.55 to 99.9% per dry matter. Refined sugar is sometimes tinted with ultramarine. With an excessive amount of this component in sugar syrup, hydrogen sulfide or poorly soluble decomposition products of ultramarine can form.

Sugar substitutes

In the non-alcoholic industry, not only sugar is used, but also its substitutes. They are used in the production of some low-calorie drinks for diabetics.

Sweet substances that can be sugar substitutes include food saccharin, sorbitol, xylitol, aspartame, etc.

Food saccharin (benzoic acid orthosulfimide) is a sweet substance obtained from toluene by chemical synthesis.

It is an imide of orthosulphobenzoic acid. This product is used only in the production of drinks for diabetics: saccharin is 500 times sweeter than sucrose. It is not absorbed by the body and therefore has no nutritional value.

Food sorbitol is used only for the preparation of soft drinks for diabetics. It is a hexahydric alcohol, is a product of the hydrogenation of glucose.

The content of sorbitol in the preparation is not less than 99.0% by weight of dry matter; mass fraction of ash - no more than 0.1%.

Food Xylitol is a pentahydric alcohol. These are white crystals (a slightly yellowish tint is allowed), sweet in taste, odorless, highly soluble in water. Xylitol is obtained from pentose-containing plant materials (cotton husks, corn cobs).

Aspartame is often used in the production of soft drinks.

Aspartame is a derivative of two amino acids - aspartic and phenylalanine. Sweetness is 200 units. Its disadvantage is low stability in solutions, which depends on pH and temperature. The half-life at pH 4.2 and 25°C is 260 days. The value of the allowable daily consumption(DSP) - up to 7.5 mg / kg of body weight.

Aspartame (synonyms: Nutra Sweet, Sladex, etc.) is a dipeptide sweetener in the form of a white crystalline powder with limited water solubility. The sweetness of aspartame is similar to the sweetness of sucrose, but its sensation comes a little later than that of sucrose. Aspartame has the ability to enhance the taste and aroma of many citrus juices and drinks, and does not cause dental caries.

The use of sweetener blends is currently recommended. A synergistic effect was found when mixing some sweeteners (saccharin and aspartame, oschelsulfame and aspartame, etc.), while their joint concentration decreases, which is necessary to create a certain sweetness, the taste approaches the taste of sucrose.

Fruit and berry semi-finished products

Fruit and berry concentrates used for the preparation of soft drinks include various juices (fruit and berry natural, fruit and berry spirited, fruit and berry fermented and alcoholic, fruit and berry concentrated), grape vacuum must, extracts, fruit drinks, fruit and berry natural syrups.

Fruit and berry semi-finished products should be stored in clean, dry, well-ventilated rooms at a temperature of 0 to 20C and a relative humidity of no more than 75%.

Natural fruit and berry juices give drinks the taste and aroma of natural fruits, and also increase their nutritional value, since sugars, organic acids, vitamins, microelements and other useful extractive substances of fruits are added to drinks with juices. In production, only clarified juices are used (to avoid the formation of turbidity and precipitation in drinks).

Natural juices come in lacquered glass or tin cans.

Fruit and berry alcoholized juices are obtained by pressing from crushed fresh fruits and berries, followed by canning rectified alcohol and separating by filtration or decantation of precipitated suspended solids.

In appearance, the juices should be transparent, without turbidity and sediment, mold, and other signs of spoilage. Color, taste and aroma should correspond to the fruits from which they are prepared. The volume fraction of ethyl alcohol in all juices is 16.0%.

Alcoholized juice is packaged and transported in oak barrels or cisterns.

Fermented-alcoholized fruit and berry juices are made by alcoholic fermentation of fruit and berry juice or juice obtained from pre-fermented pulp. Fruit and berry fermented-alcoholized juices should be free of extraneous tones.

The volume fraction of ethyl alcohol in these juices is 16.0 0.3% vol. Fermented-alcoholized juices are poured into oak barrels, bottles, metal and reinforced concrete containers, covered inside with a resistant protective coating.

Fruit and berry concentrated juices are thick liquid in appearance, taste and smell are close to the original ones. It is allowed to have a small sediment of protein and pectin substances at the bottom of the container. Concentrated juice is packaged in glass bottles, cans up to 10 liters, wooden barrels with polyethylene liners up to 100 liters.

Grape vacuum must used in non-alcoholic production is obtained from white and red grapes.

In appearance, the vacuum wort is a homogeneous viscous mass without foreign particles. The color of the must from white grapes can be from amber, golden to the color of strong tea, from red grapes - red of different shades. The aroma, taste and smell are pure, characteristic of grape must. The mass fraction of solids in the vacuum wort is at least 75%. The concentration of sugar in terms of invert is not less than 65%. Vacuum wort is packaged in wooden barrels with a capacity of 100 to 300 liters, cans, double polyethylene bags, enclosed in wooden barrels with a capacity of 100 to 300 liters, or cans. Warranty period of storage from the moment of its shipment by the supplier is 12 months.

Fruit and berry extracts are concentrates of clarified fruit and berry juices or vegetable raw materials, prepared by evaporating juices under vacuum in vacuum apparatuses. In the process of evaporation, a significant part of the water is removed, as a result of which the dry matter content in the extract becomes 5-10 times higher than in the original juice.

In appearance, the extracts are a clear liquid, the color is from red to dark brown, the taste is bitter.

Due to the high acidity, the extracts have good storage stability. The shelf life of Leuzea extract is 1 year, and Eleutherococcus 3 years. Extracts are packaged in lacquered tins or glass bottles up to 2 liters, as well as in wooden barrels up to 100 liters with polyethylene liners.

Cranberry fruit drink, used for the production of soft drinks, is a semi-finished product with the aroma, taste and color of cranberries, in appearance it is a transparent liquid, without turbidity and sediment, opalescence is allowed. receive cranberry juice fermentation of fresh crushed cranberries with yeast, followed by separation of the juice from the pulp and keeping it for 4 months at a temperature not exceeding 5C. Color from pink to dark red. The content of solids is 3.5 ... 4.4 g per 100 g of the product, alcohol is not less than 15 mass, acidity is in the range of 22.0 ... 34.4 cm 3 of sodium hydroxide solution with a concentration of 1 mol / dm 3 per 100 cm 3 of fruit drink.

Fruit and berry natural syrups are obtained by dissolving sugar in natural fruit and berry juices without adding water. Syrups are produced sterilized and unsterilized.

The resulting syrups are a clear thick liquid without sediment. The taste of syrups is pronounced sweet or sweet and sour, corresponds to fruit and berry juices from which they are made, the color is close to the natural color of the juices. Mass fraction of solids in juices is not less than 68.0%, sugar - not less than 62.0%. Titratable acidity (in terms of malic acid) should be 0.2 ... 1.0% for various syrups. fruit and berry syrups come in metal and glass jars, in bottles with a capacity of 10 liters.

Food acids

The pure taste of drinks is mainly due to organic acids. As a taste perception, acidity depends on the degree of dissociation and the perception threshold of food acids. For the preparation of soft drinks, various food acids are used: lactic, citric, tartaric, orthophosphoric, ascorbic and sorbic. Ascorbic acid is used to fortify drinks, sorbic acid - to increase their stability, tartaric acid - to produce dry effervescent and non-effervescent drinks, lactic acid - only for making kvass.

Food lactic acid (C 3 H 6 O 3) is produced of the highest, I and II grades, it contains lactic acid itself, respectively, not less than 37.5; 37.5 and 35%. It should be clear, free of sediment and odor.

Food citric acid (C 6 H 8 O 7 H 2 O) /GOST 908/ is colorless crystals. When dissolved in water, a 2% solution of citric acid should be transparent, with a pleasant sour taste, odorless and mechanical impurities.

Citric acid is obtained by fermenting molasses with a special mold strain Aspergillus niger.

Apply citric acid of the highest and I grades. The content of citric acid in a commercial preparation in terms of monohydrate must be at least 99.5% (for the highest and I grades). Ash content not more than 0.1% for premium and 0.35% - for grade I. The content of salts of heavy metals, barium, oxalic and ferrous-cyanogen-hydrogen acids is not allowed.

Guaranteed shelf life of citric acid is 6 months from the date of manufacture; when packing acid in corrugated cardboard boxes with an inner lining of parchment - 3 months from the date of manufacture.

Food tartaric (tartaric) acid [(CHOH) 2 (COOH) 2] (GOST 21205) is used along with citric acid, but gives drinks a slightly coarser taste.

Tartaric acid is obtained from potassium and calcium salts (tartrates), which are waste products of viticulture and winemaking.

Acid is issued the highest and I grades. In appearance, they are colorless large or small crystals or White powder. The content of tartaric acid must be at least 99% by weight.

Tartaric acid dl (TU 6-09-3938) is synthesized from raspberry anhydride and hydrogen peroxide. It is a white crystalline powder with a mass fraction of acid of at least 99%. Used as wine.

Food phosphoric acid (H 3 RO 4) grade A (GOST 10678) is used for the manufacture of soft drinks. Its consumption should not exceed 20% (on dry matter) of the amount of citric acid used for the preparation of drinks. Orthophosphoric acid is soluble in water in any ratio.

Food ascorbic acid (C 6 H 8 O 6) is obtained synthetically from glucose. In appearance, it is a homogeneous crystalline powder of white color, odorless, sour taste, without foreign taste. The commercial acid of ascorbic acid must contain at least 99.0% of the mass, the content of salts of heavy metals is not allowed.

Sorbic acid (CH 3 - CH \u003d CH - CH - CH - COOH) is used to increase the stability of soft drinks. It is sparingly soluble in cold water, easily reacts with solutions of carbonic salts of alkali and alkaline earth metals, forming easily soluble potassium, sodium, calcium sorbates.

In appearance, sorbic acid is a white or slightly yellowish crystalline powder with a slight characteristic odor, melting point 130C, solids content in terms of the equivalent of sorbic acid should be at least 99.0% of the mass.

Carbon dioxide

In the production of soft drinks, liquefied carbon dioxide is used, which, in the process of saturating it with water and drinks, passes into a gaseous state.

Carbon dioxide is obtained from gases generated during the combustion of coke, coal and natural gas, during roasting from various carbonates (limestone, chalk, marble, etc.), as well as during the fermentation of beer wort and mash in alcohol production.

The volume fraction of carbon in the liquid and gaseous state must be at least 98.8%. In food carbon dioxide, there should be practically no impurities such as carbon monoxide, hydrogen sulfide, hydrochloric, sulfuric and nitric acids, ammonia, monoethylamine. Mass fraction of moisture is not more than 0.1%, content mineral oils no more than 0.1 mg/kg.

Liquid carbon dioxide is transported and stored at the plant in steel cylinders under a pressure of 6.5 MPa (at 20C) or specialized isothermal vessels at a temperature range of -43.5…-11.3C and a pressure of 0.8…2.5 MPa. Cylinders with carbon dioxide are recommended to be stored in a supine position at a temperature not exceeding 30C.

Dyes

One of the important organoleptic properties of soft drinks is their color. As dyes, natural or synthesized substances are used. In the production of soft drinks, preference is given to natural dyes.

Natural coloring agents are added to soft drinks with fruit juice and concentrates, various extracts. Natural food dyes include: color, eno dye and dyes obtained from elderberry, blueberry pomace, dogwood, cherry and other fruits and berries; to synthetic - tartrazine F and indigo carmine.

Kohler is a natural dye, it is an aqueous solution of caramelized sucrose, obtained from granulated sugar by heating to a temperature of 180 ... 200 C. When heated above 170 C, dehydration of sucrose occurs with the formation of anhydrides of various sugars, fatty acids, dark-colored (humic) compounds, and other substances. At the same time, along with caramelization of sucrose, oxidative processes occur with the appearance of oxidation products, volatile and non-volatile organic acids. The resulting caramels are coloring substances. .

Kohler has the appearance of a dark brown viscous liquid, slightly bitter taste with a solids content of at least 70% by weight. Let's well dissolve in water. Does not react with acids and other components of soft drinks.

Kohler gives drinks a light yellow to yellow-brown color. Colors obtained with tinting are resistant to light, a 4% solution should have a brown color and, after settling for 24 hours, should not precipitate.

The finished color scheme is stored in a cool, dry place in collections made of glass enamel, aluminum or stainless steel, closed with lids. Collectors should have jackets for heating and stirrers.

Eno-dye is obtained from pomace of dark grape varieties. The main coloring matter of such grapes is enin. The enin molecule contains glucose, which is split off at high temperature under the action of acids, and enin passes into enidine.

Enidine, or eno dye, is extracted from squeezed grape pulp with a 1% hydrochloric acid solution. The resulting solution is concentrated under vacuum to a liquid or pasty consistency.

Eno dye is a mixture of dyes belonging to the class of anthocyanins, extracted from pomace of dark grape varieties. The liquid dye has a dark red color, a slightly vinous and sour taste and smell, and completely dissolves in water, forming a clear solution. Depending on the active reaction of the medium, the color of the eno dye is different: from red to purple. The eno dye is stored in clean, dry, darkened rooms at a temperature of 0 ... 25 ° C in glass container with a capacity of not more than 10 liters, placed in wooden boxes or baskets lined with straw or shavings. Warranty period of storage is 1 year from the date of manufacture.

Indigo carmine is the disodium salt of indigo disulfonic acid. The dye is a bluish-black non-separating paste containing 35% solids and 24.5% pure dye. The paste is dissolved in water in a ratio of 1:10. An aqueous solution of the dye has Blue colour. Indigo carmine is packed in glass jars with a capacity of 10 liters, stored in a darkened cool room.

Tartrazine F is an orange-yellow finely crystalline powder containing at least 85% dye. It dissolves well in water and water-alcohol solutions. For tinting drinks, they are used in the form of aqueous solutions of 3:100 and 5:100. Aqueous solutions of tartrazine are stable to light and do not change their color when heated to 105°C.

Tartrazine is slightly soluble in ethyl alcohol. Tint drinks in yellow different shades, with a very strong dilution in water, a pronounced greenish tint appears.

aromatic substances

One of valuable properties drinks is their pleasant aroma. To communicate aroma, aromatic infusions and essences containing a variety of odorous substances of organic nature, as well as alcoholic solutions of essential oils and aromatic substances, are added to drinks. Aromatic infusions are water-alcohol solutions of fragrant substances obtained by extracting aromatic plant materials. For the preparation of such infusions, the peel of citrus fruits (lemons, oranges, tangerines), the seeds of some fruits (cherries, peaches, almonds), the bark of woody plants (cinnamon), flowers (linden blossom, rose petals), blackcurrant buds, etc. are used.

A number of flavoring and aromatic additives are prepared directly at enterprises according to the current technological instructions. These additives include: infusion of bay leaf, cinnamon, cloves, raikhon herbs and others.

Essences are concentrated water-alcohol solutions of various aromatic substances. Essences are natural, synthetic and combined.

Natural essences are made by extracting aromatic substances. For the preparation of soft drinks, lemon, tangerine and orange essences are widely used. Natural essences can be obtained by vacuum distillation from fresh fruits, filled with a water-alcohol mixture. Due to the fact that the terpenes contained in natural aromatic substances are insoluble in water, turbidity of drinks can occur, therefore, when preparing the essence, essential oils undergo deterpenization, i.e. terpenes are removed.

Synthetic essences (OST 18-103) are solutions of aromatic substances obtained by chemical synthesis. The following esters are used as aromatic substances: ethyl butyrate (for pineapple essence), amyl acetate (for pear essence), ethyl acetate (for pear and other fruit essences), amyl valerianate (for apple essence), ethyl formate (for rum essence), vanillin (4-hydroxy-3-methoxybenzaldehyde) and coumarin (orthohydroxycinnamic acid lactone) - for cream soda, as well as citral - unsaturated aldehyde (for lemon and orange essences). The mass fraction of aromatic substances in synthetic essences varies depending on the type of essence from 4 to 13%, and the volume fraction of alcohol - from 37 to 95%.

Combined essences contain, along with natural flavors, synthetic aromatic substances (composition for the drink "Lemonade" and essence "Blackcurrant").

There should be no turbidity even when 1 ml is dissolved. synthetic essence in 1000 ml of water. Synthetic essences should not contain lead and copper.

Essences are stored in a dark, tightly closed glass container, in which no air space is left. Since the volatility of essences increases with increasing temperature, they are stored in a darkened room at a temperature not exceeding 25C.

Citrus alcohol infusions (OST 18-115). For the preparation of soft drinks, lemon, orange, tangerine and grapefruit infusions are used. Infusions are made by extracting the essential oil with a water-alcohol solution from the peel of a lemon, orange, grapefruit or mandarin peel. The taste and aroma are pronounced, characteristic of the corresponding fruits, light yellow in color, the volume fraction of alcohol is 65%.

When diluting infusions with water in a ratio of 1:100, a slight turbidity is allowed, which disappears after filtration. The mass fraction of essential oil in lemon infusion is 0.40%, in orange - 0.45%, in tangerine - 0.30%.

Guaranteed shelf life of citrus infusions is at least 8 months from the date of manufacture.

Coffee infusion (TU 18-6-200) is a dark brown transparent liquid, opalescence is allowed, and during storage - a small precipitate, a smell characteristic of the aroma of coffee, tastes bitter, without foreign taste, when dissolved with water in a ratio of 1 :50 transparent solution, the alcohol content should be at least 42.0% in total volume, solids should be at least 1.5 g / ml.

Peppermint and tarragon infusions are clear green liquids with a corresponding smell and taste. The volume fraction of ethyl alcohol in tarragon infusion is 60.6%, in peppermint infusion 81.0%, the mass fraction of essential oil in mint infusion should be at least 5%.

Store infusions in a darkened room at a temperature not lower than 2C and not higher than 20C.

Essential oils are products obtained by extraction or steam distillation from essential oil raw materials: laurel, eucalyptus, rose, citrus fruits, cloves, lemon wormwood, etc. They are produced according to various regulatory documents. Used in the form of alcohol solutions. Vanillin (GOST 16599), isobornyl acetate (TU 18-16-237) is added to some drinks - a colorless liquid with a smell of pine needles; spices, honey (GOST 19792), beekeeping products (apilak, extracts flower pollen, dairy products (condensed and dry whey, skimmed milk powder).

Fragrances used for the production of soft drinks are isobornyl acetate and vanillin.

Isobornyl acetate (C 12 H 20 O 2) is an acetic ester of isoborneol, obtained by vacuum distillation of pichtosin, a product of acetylation of technical camphene with acetic acid. In appearance, it is a clear, colorless liquid with an odor of pine needles. The ether content must be at least 98%, the content acetic acid- no more than 0.25% of the mass. Packed isobornyl acetate in aluminum or galvanized barrels. Store in a dark, cool room; during storage, an increase in the content of acetic acid to 1.0% is allowed. Guaranteed shelf life of isobornyl acetate is at least 6 months.

Vanillin is a substance derived from guaiacol and lignosulfonates. Vanillin is a white to light yellow crystalline powder with a characteristic odor. The vanillin content must be at least 99.0%. In vanillin obtained from lignosulfonates, the content of pure vanillin is allowed at least 98.5%. Vanillin should be stored in clean, dry, cool, well-ventilated rooms at a temperature not exceeding 25C and relative humidity not more than 80%.

Beverage concentrates and compositions

Recently, concentrates, compositions and concentrated bases have been widely used for the preparation of soft drinks. As a rule, they consist of two parts: aromatic and extractive. Organoleptic and physico-chemical parameters of these products must comply with the requirements of GOST 28188-89.

As a rule, beverage concentrates in appearance are a thick liquid with an intense specific taste and aroma, corresponding to the components included in its composition.

For example, the concentrate for the drink "Apple" is prepared from concentrated apple juice, aromatic essence "Apple Crimean", citric acid and color. The concentrate is a thick viscous liquid of dark brown color with apple aroma, sour taste without foreign impurities. The solids content should be 70.0% by weight, acidity 4.4% by weight. This concentrate is packaged in glass and tin cans, wooden barrels and cardboard drums with polyethylene liners. Store in refrigerated rooms at a temperature not lower than 2C and not higher than 10C.

In recent years, drinks based on domestic raw materials have replaced drinks based on imported concentrates from various companies. These are Coca-Cola, Pepsi-Cola, as well as drinks from Deler, which has a very diverse assortment, Milesta, etc. Concentrates from foreign companies are usually supplied as a mixture of flavoring and aromatic substances, including dyes . They are well stored and transported, used to prepare drinks in small doses. These factors determined their wide distribution. .

Beverage compositions are mixtures containing all blending syrup components specified in the recipes, with the exception of sugar syrup and citric acid. Such compositions of domestic production include compositions of drinks "Lemon", "Orange", "Sayany-tonic", "Lemonade".

In appearance, the compositions are dark-colored liquids with long-term preservation due to high content alcohols in citrus infusions introduced into them. In a dry room at a temperature not lower than 2C and not higher than 20C, the preservation of the composition is guaranteed for 6 months.

Often, enterprises use concentrates for the drink from the Deler company, as well as powdered vitamin components, which include flavorings, dyes, fruit and berry semi-finished products. Each concentrate and vitamin component has its own registration numbers.

preservatives

To increase the stability of soft drinks, the following chemical preservatives are used: sorbic and ascorbic acids, sodium benzoate, juglone, plumbagin.

Sorbic acid has an inhibitory effect on yeasts and molds, which is enhanced in acidic environment. Sorbic acid is added to the blend in an amount of 0.03% by weight, which leads to an increase in the stability of the drink (up to 20 ... 23 days).

Ascorbic acid, which has antioxidant properties, enhances the effect of sorbic acid when used together, and the stability of the drink increases up to 20 ... 30 days.

Juglone and plumbagin, which affect the microflora of the soft drink, increase its durability up to 30 days.

The sodium salt of benzene acid (sodium benzoate) is allowed to be used to increase the stability of drinks prepared with fruit juices. Its quantity should not exceed 177 mg / l.

1.2.2 Technology for the production of fruit carbonated drinks

Water and water treatment

Water is the main raw material, which largely determines both the flow of technological processes and the quality of finished products.

At factories producing soft drinks, water consumption depends on the recipe and production technology of the drink, as well as the water supply scheme. At domestic plants, the water consumption is 0.166 and 0.020 m 3 /dal of the drink (in the absence of a compressor unit). In the production of commercial syrups, the water consumption is 0.056 m 3 /dal.

Water supply sources are divided into waters of underground deposits (artesian and ground) and waters of open reservoirs.

Open reservoirs are the most common source of industrial water supply, the salt composition of water and the nature of impurities, as a rule, are not constant and change during the year depending on precipitation and flood waters. The salt content in most river waters is 40...700 mg/l, although the water of some rivers is characterized by high mineralization. The content of organic impurities in the waters of open reservoirs is quite high - 2 ... 150 mg / l.

Salt composition of water and its influence on the technological process

The properties of water are determined by the concentration and ratio of salts dissolved in it, contained in the form of cations and anions. Of the cations, H +, K +, Na +, Ca 2+, Mg 2+, Fe 2+, Fe 3+, Mn 2+ are of the greatest practical importance; from anions - OH, HCO 3? ,Cl? , SO 2- 4 , SiO 2- 3 , NO ? 2, NO 3 .

In the molecular and colloidal state, there are organic substances, as well as CO 2, O 2, N 2 gases dissolved in water.

Water hardness is characterized by the presence of calcium and magnesium ions. This indicator is taken into account when assessing water for practical use. Distinguish the following types water hardness:

General, due to the content of all magnesium salts in water - Ca (HCO 3) 2, Mg (HCO 3) 2, MgSO 4, CaSO 4, CaCl 2, MgCl 2;

carbonate, or temporary, due to the presence in the water of bicarbonates (salts of HCO 3) of calcium and magnesium, which are removed in boiling due to destruction and transition to slightly soluble carbonates that precipitate;

non-carbonate, or permanent, remaining in the water after the removal of bicarbonates from it.

The total alkalinity depends on the presence of hydroxides, carbonates and bicarbonates of calcium, magnesium and sodium in the water; determine it in order to establish the suitability of water for brewing.

Water pollution by organic substances is judged by the indicator of oxidizability. When assessing the suitability of water for technological purposes, not only the chemical composition, but also the bacterial composition is taken into account, since water is used for washing technological equipment, tanks, premises, etc.

In addition, it is proposed to characterize water according to the indicator Psh - suitability for alkalinity, equal to the ratio of calcium ions to total alkalinity: Psh = Ca 2+ / Shch. 1, there is no need to pre-treat the water.

The content of hardness salts, chlorides, sulfates, dry residue in water and alkalinity primarily affect the quality of soft drinks. The alkalinity of water reduces the acidity of the drink, so it is necessary to increase the amount of citric acid added to the sugar syrup. The consumption of citric acid also increases when the permissible limits of total hardness are exceeded, since calcium and magnesium bicarbonates interact with pectin and tannins of juices, forming complex compounds that cause the drink to become cloudy. Along with this, one should not underestimate the total content of salts (dry residue), which are involved in the formation of taste, and also cause precipitation, chemical instability, changes in the appearance of the drink, etc.

Water quality requirements

Maximum allowable concentration of individual elements in water, mg/l

Iron (Fe 2+ + Fe 3+) 2...3

Manganese (Mn 2+) 0.5

Chlorides (Cl?) 350

Phenols 0.001

Water for soft drinks, as well as for beer, must meet the requirements of the standard for drinking water subject to additional requirements.

Thanks to the establishment of norms for the salt composition of water, it is possible in each individual case to decide on its use for the production of malt, beer and soft drinks without preliminary preparation, to choose a rational method of conditioning its composition.

1.2.3 Technological stages of production

carbonated soft drinks

The main stages in the production of soft drinks are shown in Figure 1.

When using the synchronous-mixing method of bottling, first the blend syrup is mixed with deaerated water, and then the resulting water-blend mixture is subjected to cooling and saturation with carbon dioxide.

At the factories producing Pepsi-Cola and Fanta drinks, syrup is prepared both cold and hot. cold way- dissolving sugar without heating and filtering the syrup. The mass fraction of solids in the syrup should be 60 - 65%.

Bottling of drinks can be carried out in two ways: by dosing the blended syrup into bottles, followed by topping up with carbonated water; saturation of a mixture of deaerated water and blended syrup carbon dioxide with subsequent bottling already ready drink into bottles.

Saturation of water with carbon dioxide is carried out in saturators, and drinks - in synchronous mixing plants. The water is pre-filtered, softened if necessary, cooled to a temperature of 2 - 4 C and deaerated (i.e., dissolved gases that interfere with the introduction of carbon dioxide are removed from it. The mass fraction of carbon dioxide in drinks is 0.2 - 0.5%.

Bottles filled with a drink undergo rejection, labeling and are stored in a warehouse until sold at a temperature not exceeding 12 C.

Preparation of blended syrups

A blended syrup is a semi-product of non-alcoholic production, which is a mixture of all the components of the drink (with the exception of carbonated water).

The process of preparing a mixture from individual components is called blending, and the resulting mixture is called blending syrup. For blending, closed enameled, aluminum or stainless steel apparatuses with paddle or propeller mixers are used.

Blending is the main and most important stage of production, on which all indicators of the quality of the finished product depend.

Preparation of components for blending

Fruit and berry juices and fruit drinks must be filtered before being added to the mixture. The transparency of fruit extracts is checked by

4-5 times dilution of the extract sample with water. If the extract is opaque, it is diluted with water in a ratio of 1:5, thoroughly stirred, allowed to stand for 2-3 hours, then filtered and used to prepare blended syrups.

Citrus infusions and food essences are carefully filtered before use to remove turbidity or sediment. If the test infusion has a high content of terpenes, it is diluted with water in a ratio of 1:5, stirred well and settled for 12-18 hours. The infusion solution is then filtered until completely transparent.

Food acids are added to the mixture as follows: citric acid - in the form of a 50% aqueous solution, lactic acid - without dilution. The prepared acid solutions are thoroughly mixed. Acid solution is good for 2-3 days.

Dyes - color, eno dye from elderberries and synthetic - are added to the blend in the form of pre-prepared aqueous solutions. Kohler with a mass fraction of solids of 70% is diluted with water in a ratio of 1:5 or 1:10. It gives drinks a color ranging from light yellow to dark brown. The eno dye may be liquid or pasty. When blending, its aqueous solution is used. Indigo carmine powder is diluted in hot water in a ratio of 1:40, in the form of a paste - 1:10, it gives the drinks a blue color. Tartrazine F is added to the blend in the form of an aqueous solution with a concentration of 5g / 100ml, it tints drinks in different shades of yellow. Tartrazine F and indigo carmine together give a green color.

Components of blended syrups prepared for blending are stored in pressure measuring tanks installed on the platform above the blending apparatus.

Methods for preparing blended syrups. Blended syrup is prepared in cold, semi-hot and hot ways.

The cold method is used to obtain blended syrups using citrus infusions, food essences, compositions and concentrates. Sugar syrup with a temperature of 8 - 15 C is collected into the blending apparatus and then, with stirring, the remaining semi-finished products are added in the following sequence: fruit juice or extract, concentrate, wine, acid solution, dye solution, citrus infusions, compositions and food essences. All these components are thoroughly mixed, filtered and cooled to a temperature of 8-10 C.

The semi-hot method is that part of the juice or wine (50 -

70%) is put into a syrup boiler for cooking with sugar, and then heated to 50 ° C and, with stirring, the entire amount of sugar intended for the preparation of sugar syrup is added. After that, the mixture is quickly heated to a boil, and then, with stirring, add the entire amount of acid intended for blending, and boil for 30 minutes, removing the periodically formed foam.

The mixture is filtered while hot, cooled quickly, pumped into syrup collectors or blenders. Upon reaching a temperature of 20 C, the rest of the juice or wine and other components are added to the syrup according to the drink recipe in the same sequence as in the cold method.

With the semi-hot method, the taste and aromatic properties of the fruit and berry semi-finished product are preserved in the drink.

The hot method of preparing blended syrups is based on the fact that the entire norm of fruit and berry juice or wine (100%) is brought into the syrup boiler, heated to 50 - 60 ° C and, with stirring, the entire amount of sugar is poured. Further, the process is carried out in the same way as in the semi-hot method. As a result of boiling, a well-clarified syrup is obtained, the prepared drinks have good stability.

The disadvantage of semi-hot and hot methods is partial

loss of aromatic substances in the manufacture of syrup.

The industrial method of preparing blended syrups is used in specialized enterprises.

First, a white sugar syrup is prepared with a mass fraction of solids of 66-72%. After boiling and cooling it to 70C, sucrose is inverted by adding food acids. The acidified syrup is kept for 2 hours with a continuously operating stirrer, and then cooled to 15 - 20C. The consumption of acid used for the inversion of sucrose is taken into account when adding acid to the blend.

Then a blended syrup is prepared by mixing the sugar syrup and all the components provided for in the recipe. The resulting blend syrup is thoroughly mixed and determined mass fraction solids and acidity. Next, the blended syrup with a mass fraction of solids of 60-63% is filtered, cooled to a temperature of 18-20C and sent to a collector, from which the syrup is poured into a transport container.
