Is sublimated coffee harmful? The best instant coffee. Effect on the liver

Instant coffee is not inferior in popularity to the grain version. Many prefer it because of the convenience and fast food. A huge part of coffee sales in the world is instant coffee? Since its invention, it has won the hearts of many admirers. And in times Soviet Union not everyone managed to acquire the coveted jar of instant coffee. It has become scarce. Now we can buy it in any store. Lately instant coffee is no longer perceived as a full-fledged coffee. They began to scold him for his inexpressive taste and aroma, there was information that he could harm. But still, millions cannot do without it. So what is the harm of instant coffee, and how can it be useful? In fact, if you drink instant coffee, the benefits and harms will be combined in the drink.

A bit of the history of instant coffee

There are several versions of the appearance of instant coffee.

• Version one. This is the invention of an American chemist with Japanese roots, Satori Kato. There is no exact date for the appearance of this popular invention. According to historians, it could be 1899 or 1901. It is curious that Kato first came up with instant tea but it didn't become as popular. Soon the inventor suggested using the same technology to produce coffee. It was a truly historic decision. The drink turned out so successful that it soon began to be produced in industrial scale. By the way, during the First and Second World Wars, it was instant coffee that was included in the mandatory rations of soldiers. He supplanted the grain version of coffee, as it was extremely inappropriate in field conditions. But instant coffee, as it turned out, was easy enough to get. The technological process was quickly mastered by many manufacturing companies. After the Second World War, instant coffee quickly entered civilian life.
• Version two. There is an assumption that the Englishman, chemist George Constant Washington became the inventor of instant coffee. According to this version, George invented the method of making instant coffee by accident. He and his wife were in a coffee shop and enjoyed a fragrant fresh coffee. George suddenly noticed that there were barely noticeable dust particles on the silver coffee spoon. It suddenly dawned on him that it was possible to produce coffee that would simply dissolve in water. In 1906, after a series of experiments, the scientist nevertheless brought his idea to life. The drink turned out to be quite tasty and fragrant, so after three years it was put into production.
• Version three. This is the official version. According to her, the merit of the appearance of instant coffee belongs to the Swiss chemist Max Morgenstaller. Initially, this scientist simply conducted scientific experiments. He wanted to test the version that coffee is able to half dissolve in water. The result of these experiments was the new kind instant coffee. In the homeland of coffee, in Brazil, they could not get enough of the generous harvest of precious grains. But there were so many of them that there were large surpluses. They had to be saved somehow. And then Max Morgenstaller proposed to produce instant coffee from them. This happened in 1938, on July 24th. It was on this day that they began to celebrate Instant Coffee Day.

What is it made from

The fact is that the benefits and harms of instant coffee are directly related to the technological process of its manufacture. Instant coffee is produced from beans that are ground, and then the extraction method is used. But did you know that the most popular and quality grade- Arabica? It is used to produce ground coffee. But for the soluble species, they take the Robusta variety. It's cheaper, but stronger. It is an excellent raw material for industrial processing.

Now instant coffee is produced in three ways:

1. The first way is coffee powder. The easiest option. Instant coffee powder is produced. The grains are first roasted, ground, and then dried and sprayed. The grains are affected by hot water which is supplied under high pressure. Soluble substances are extracted from the coffee powder, and it turns out strong coffee yy infusion. Then this infusion is filtered and sprayed in special chambers. On the fly, the drops of the extract coagulate, dry quickly and turn into a fine powder.
2. The second way is coffee in granules. Granulated coffee is much more expensive, but at the same time, its taste and aroma are almost the same as those of powder coffee. Get it in the same way as the powder. But then the process has a continuation. To obtain granules, the powder is re-processed with hot steam. Then it is knocked down into small dense lumps - granules. The cost of this type of coffee rises precisely because of the additional steps in the technological process. In addition, the experts came to the conclusion that the additional temperature effect negatively affects the taste and aroma of coffee granules. In addition, he loses most useful qualities. In order to somehow compensate for these shortcomings, manufacturers add to their product coffee oil and fragrances.
3. The third way. Sublimation. It is the most modern. It was opened in 1965. Now it is freeze-dried coffee that is considered the highest quality instant coffee. The beans are roasted to make a strong coffee infusion. Then it is frozen, the ice evaporates, and the coffee crystals are dried under vacuum. At the same time, not only the taste, color and aroma of coffee are preserved, but also its beneficial properties.

How to choose quality instant coffee

Instant coffee, in which harm and benefit are inextricably combined, must be chosen correctly. If you want to buy really good quality instant coffee, don't go cheap. The cheaper the product, the more it will contain all kinds of additives. To make your product cheaper, dyes, flavors, chicory or barley are added to it. But expensive instant coffee is produced quite conscientiously. However, flavors are added to it. Do not believe the inscription, which says that the jar contains 100% coffee. Do not be surprised, but the share of coffee in the total mass is no more than 15%.

The highest quality coffee is insoluble. It does contain trace elements, vitamins and antioxidants. Such a drink is able to cheer up, it stimulates the production of serotonin (it is also called the "hormone of happiness"). Quality coffee It can even extend life, scientists have found. Fans of this drink are less susceptible to stress, depression, it even helps to fight overweight. But for coffee to help cope with extra pounds, nothing can be added to it, not even sugar. You need to drink only black natural coffee. It contains only 3 calories. If you drink it before a workout or other physical activity, fat will be burned better. But in order to restore strength, nutritionists recommend drinking coffee with the addition of milk or cream.

As you can see, the benefits of coffee are undeniable. But instant coffee will be useful only if you really choose quality product. But how to choose high-quality instant coffee? Checking the quality of the purchased product is quite simple. Prepare some drink and drop regular iodine into it (just a few drops). If there are impurities and all kinds of additives in coffee, it will quickly turn into Blue colour. If the drink has not changed its shade, then you are lucky and you bought a quality product.

Instant coffee: benefits and harms

From the moment instant coffee was introduced, all sorts of rumors began to circulate about it. There was an opinion that the instant version of coffee can harm the body. Others, on the contrary, believed that it could only bring benefits. Now it has become a popular opinion that there is much less left in instant coffee. useful substances, than in grain form. Since the coffee is exposed to high temperatures, he loses most aromatic oils. Because of this, instant coffee becomes non-aromatic, and its taste becomes inexpressive. To fix this, manufacturers add flavors and flavor enhancers to their product. These supplements bring taste characteristics To regular coffee in grains. Is this opinion really correct? How harmful is instant coffee? Can it be useful?

Which coffee is better to choose - instant or ground

To understand the difference between soluble and ground coffee need to understand how they are produced. Ground coffee is the result of grinding roasted coffee beans. This is the most common option. This coffee is very easy to prepare - you need to roast the grains, grind, and then brew coffee from the resulting coffee powder.

Instant coffee is obtained as a result of the following technological process. First, the grains are also roasted and ground. This is how coffee extract is obtained. Then the powder is dried. Two methods are used for this - water is frozen in it or it is exposed to hot air. The result is a completely natural product. The choice of drying method does not affect its quality in any way.

We must understand and come to terms with the fact that instant coffee has gained its colossal worldwide popularity not at all due to some amazing taste or amazing aroma. First of all, it is appreciated for convenient way brewing. It is not always possible to brew coffee. And then the soluble option comes to the rescue. To prepare it, you do not need to stand at the stove or use a coffee machine. You just need to pour it hot water. True connoisseurs of a fragrant drink have long understood that instant coffee is seriously inferior to fresh, ground beans. The taste of the drink from grains is much softer and more pleasant. In addition, it retains more useful substances. It is coffee beans that gives a charge of vivacity, stimulates the work of the brain and central nervous system, as well as cardiac activity. The soluble analogue is noticeably inferior in these indicators.

Now let's dwell on the opinion that flavors, preservatives and dyes are used in instant coffee. In fact, it is not always possible to find them there. Responsible world-famous coffee producers will not use these substances. They only apply if there has been a violation technological process. Therefore, it is better to choose a product from large famous companies. Owners of well-known world brands can vouch for the quality of their products.

Instant coffee: harm

Diuretic effect

Opponents of coffee and nutritionists emphasize that coffee can have a diuretic effect, that is, it has a diuretic effect. This is true. Coffee really for a short time stimulates increased excretion of fluid from the body. By the way, the use of coffee for weight loss is based on this effect. It removes excess fluid from the body and is thus lost excess weight. If you did not plan to lose weight, and the diuretic effect is undesirable, it can be compensated very simply. It is enough to drink a glass of water half an hour after drinking a cup of coffee. The same can be done an hour before you enjoy another cup of magical drink.

The harm of the diuretic effect is that fluid loss can lead to dehydration. But in order for it to come, you need to drink coffee simply in colossal quantities and at the same time no longer consume absolutely no liquid. And in this way, useful substances can be washed out of the body in quite a in large numbers. But in order to achieve this, you need to drink at least 5 cups of very much a day. strong drink. If you use it in moderate doses (2-3 cups of a weak drink per day), you will not be affected by such an effect. At the same time, the mild diuretic effect of coffee becomes even useful. It improves metabolic processes in the body, without affecting the established water-salt balance.

How coffee affects the concentration of calcium in the body

Again, everything will depend on the daily dose of coffee that you keep. At the norm, coffee simply will not be able to remove calcium from the body and harm bone tissue or tooth enamel. If you are afraid that the body will still begin to lose calcium, which is so important for it, then use a very simple advice- drink coffee with milk. Milk contains a lot of the calcium you need, which is easy to digest. So you will not only save your reserves of this mineral, but also significantly replenish them. By the way, instant coffee goes well with milk or cream. You should also include in your diet dairy products and cottage cheese. Curdled milk, yogurt, kefir and fermented baked milk are very rich in calcium.

Addiction

Opponents of coffee argue their dislike for this drink by the fact that it can be addictive. This is not entirely true. In fact, addiction develops not so much from coffee as from the ritual of its preparation. As you know, the main merit of the invigorating effect that coffee has belongs to the alkaloid caffeine. There is a lot of it in this drink. Some believe that caffeine can be addictive. But there is not a single scientific work that would confirm this. Studies on how coffee affects the body have been carried out in many countries. They found some pattern. Indeed, some people just get used to drinking a cup of flavored drink every morning. If they are deprived of this opportunity, they become lethargic, suffer from headaches, weakness, and even mild depression.

Coffee can indeed develop a sort of mild addiction. Its culprit is the alkaloid caffeine, which is contained in this drink in large quantities. It is a powerful body stimulant. It is able to increase efficiency, physical and mental activity. But such dependence is quite rarely physiological. In order for a person to develop physical dependence, he must drink strong coffee just in huge quantities. Most often, a psychological form of dependence develops. By the way, addiction can develop both from instant and ground coffee. To avoid it, you need to drink coffee in reasonable quantities. Scientists have done serious research and found that safe dose coffee for a healthy adult is only 1-2 cups. However, it should not be too strong. In this case, addiction will not appear. For healthy person without chronic diseases a small amount coffee is not only safe, but even useful. Coffee helps maintain vigor, improves mental and cardiac activity, stimulates the central nervous system. Curiously, it can improve memory and increase attention. Cup fragrant coffee, drunk in the morning, will drive away the remnants of sleep and increase working capacity. This is a good incentive that will help you maintain your ability to work at the proper level throughout the working day. The main thing is not to abuse this doping.

But coffee can only harm if you suffer from hypertension, chronic cardiovascular or digestive systems. In this case, it is generally better to refuse it. Just replace it with another drink that will help you cheer up. There are enough of them. An invigorating effect, for example, has green and black tea, rosehip, mint tea, fresh juices citrus fruits, etc.

Effect on blood vessels and heart

Coffee can really harm blood vessels and the heart, but only if they are already sick. It is extremely harmful to drink really strong coffee. Large doses caffeine can cause high blood pressure and disturb the heart rhythm. In order to get a similar negative effect from the drink, you need to drink at least 4-6 cups of strong coffee a day. If you drink no more than two cups, then the caffeine from this aromatic drink, on the contrary, will support the heart. vascular system and even bring the pressure back to normal. This one is especially helpful magic drink those who suffer from reduced pressure. This easy way normalize it. But with migraines and hypertension, small doses of caffeine will help to cope with a headache.

Effect on the liver

Information about how coffee affects the liver is quite contradictory. Some believe that nothing but harm can not be expected. Others see only positive influence. This is where the amount of caffeine comes into play. A high dose of caffeine and its long-term use can indeed cause toxic hepatitis. But in order for it to develop, you need to drink simply unimaginable doses of coffee. long time. At the same time, liver cells will also destroy other drinks, such as strong black tea, alcohol, and nicotine. But moderate doses of caffeine will even prevent such a terrible disease as cirrhosis. And for those who already suffer from this disease, caffeine may even be a medicine that can prolong their lives.

Influence on the gastrointestinal tract

Instant coffee can negatively affect the digestive tract. This is due to the fact that it often uses additives that irritate the gastric mucosa. With excessive use of instant coffee, especially low quality, you can even provoke the development of gastritis or ulcers. After it, heartburn and disruption of the stomach are often observed. To avoid negative impact, it is better to add milk to the drink. It prevents irritation of the gastrointestinal mucosa.

Cholesterol level

Among nutritionists, there is an opinion that coffee can increase blood cholesterol levels. But this effect will be observed only if ground coffee is really abused. It contains the substances caveol and cafestol. They can indeed increase the degree of absorption in the large intestine of cholesterol. Because of this, its level in the blood plasma may increase. But in instant coffee, these substances are not at all. Therefore, it cannot provoke an increase in cholesterol levels in any way.

As you can see, 2-3 cups of instant coffee a day can even provide some benefits. The main thing is not to forget about the sense of proportion. Remember that caffeine is classified as a medicinal substance. As with any medicine, it is strictly forbidden to exceed the recommended dose. Otherwise, the medicine can quickly turn into poison. Instant coffee combines both harmful and beneficial properties. The main thing is to buy a quality product. Experts, however, still recommend using natural coffee beans, and brew instant coffee only when it is simply not possible to brew coffee from beans.

Each person has his own morning ritual, without which he cannot wake up. Someone cannot imagine the morning without a mini-exercises, someone is perfectly invigorated by a contrast shower. However, most people claim that they start their morning with a cup of coffee. The beneficial properties of the drink have been repeatedly disputed by scientists, but in the end, the researchers still came to the conclusion that it is one of a kind and unique. He contains a large number of caffeine, which tones the body. Despite the intense effect on the body, the drink does not harm it. Let's learn more about its history, useful and harmful properties. And also how to make coffee.

A bit of history

Coffee is the oldest drink, the appearance of which dates back to the beginning of the 16th century. Ethiopia is considered to be his homeland. There are many legends that explain how people came up with the idea of ​​brewing. One of them says that once an observant shepherd noticed that the leaves coffee tree strange effect on living creatures. Sheep and goats showed the greatest activity after eating this plant.

To test the wondrous power of the leaves, the shepherd collected them and insisted on water.

3. Contains many vitamins. Natural product - a storehouse beneficial trace elements such as phosphorus, iron, sodium, etc.

Coffee, the beneficial properties of which we examined above, is not only tasty, but also healthy drink. It has a beneficial effect on the body, if the measure is observed when using it.

Instant coffee

Unlike a natural product in "sticks" and jars, it will not bring any benefit. Rather, it will only worsen the state of health. The harm of instant coffee has long been proven by doctors:

1. Causes addiction. People who have been drinking the drink for a long time note that they cannot live a single day without it. Some experts argue that coffee is a kind of drug. Although it acts on the body less powerfully, it is just as addictive.
2. Contains many preservatives. It has been proven that instant coffee contains only 15-20% of natural grains, the rest is flavors and additives. They help save on coffee production, but do nothing to improve the health of coffee drinkers.

How to choose coffee beans?

If you prefer to grind the product immediately before preparing the drink, then most likely you are interested in how to choose coffee beans. First of all, pay attention to the packaging. It must be whole. Grains should not come into contact with air and the environment, otherwise they will lose their taste and smell.

Find out where the plant was grown. Please note that the strongest coffee is produced in Ethiopia, India, Indonesia, Latin America. The packaging should have a transparent window so that you can get acquainted with the condition of the grains. They should not have chips. It is desirable that they be whole. Special attention notice their color. Keep in mind: the lighter the coffee, the more sour it is, the darker, the bitterer and stronger.

How to prepare a drink?

Many people have a question: “How to brew coffee correctly?” Meanwhile, there is nothing complicated in this procedure. First you need to grind the grains with a special machine. Then you need to take two teaspoons and add sugar to taste. Pour the mixture with 150 grams of water and put on a slow fire.

Try not to let the drink boil completely. Take it off the heat as soon as you see small bubbles forming on its surface. After 5-7 minutes, the aromatic drink will be ready. It remains only to pour it into a cup and enjoy the wonderful taste.

Contraindications

Unfortunately, this drink is not for everyone. Coffee has a number of contraindications:

• Insomnia. Coffee tones and invigorates. With insomnia, these properties are useless.
• Constant palpitations. If you notice yourself that due to any, even the most insignificant loads, you have shortness of breath and slight tachycardia, then give up coffee. Also, you can not drink a drink for people who have suffered a myocardial infarction.
• Hypertension. Not everyone knows about the property of coffee to increase blood pressure. But for hypertensive patients, this is extremely dangerous, since their health may worsen.
• lactation period. Doctors claim that overuse coffee drink while breastfeeding a baby can harm the quality of milk up to its loss.

If you have at least one of the above ailments or contraindications, the best solution would be to give up the flavored drink.

The drink appeared on store shelves more than 75 years ago, and is popular due to the ease of brewing and good taste. Let's figure it out together - is there any harm to instant coffee, how useful is such an analogue of natural grains, what is it made of instant product What are its properties and effects on the human body.

History says that the first and only creator of the invigorating product in 1899 was Satori Kato. However, the technology for the production of instant coffee was not widely used and its production was not launched. And only after almost half a century, a Nestle specialist presented unique product- granules that instantly dissolved in water and turned into a drink that, with its properties, was very reminiscent of natural. Today, such a delicious, aromatic coffee product is made on almost all continents.

It is quite often mistakenly believed that the benefits of instant coffee lie in the lower caffeine content compared to natural beans. But chemical composition two drinks indicates otherwise - one serving of a natural treat contains 80 mg of caffeine, while a cup of an instant drink contains 65 mg.

Caffeine is a rather complex substance, if we talk about its effect on the body, its properties depend on the state of health and individual characteristics person. For example, for hypotensive patients, it is indispensable for giving vigor, if you refuse to use it, the result will be a feeling of fatigue and headaches. The feeling of activity and clarity of thinking arises due to the ingestion of sugar into the bloodstream, which provokes caffeine.

Note: If you have problems with blood pressure, but do not want to give up eating a treat, choose drink recipes with milk.

The harm of instant coffee

The main danger of the drink is the use of grains with defects in the production or non-compliance with the production technology.

Another possible harm product - the content in the composition of flavors, dyes and other additives that are hazardous to health, which affect the taste and aromatic properties. As part of a natural drink, the amount of such dubious components is minimal. In this sense, natural grains are healthier than an instant drink.

For people with pathologies of the gastrointestinal tract, it is better to replace the product. It is important to remember that with excessive enthusiasm fragrant drink vitamins are flushed out of the body. Also, a drink with a high sugar content can cause harm to health.

The effects of instant coffee are actively debated. The danger lies in the following - a person receives "fake" energy. Caffeine has a stimulating effect on the body, while sugar enters the blood, the brain works more actively and there is a feeling of cheerfulness. As a result of this deception, the level of the stress hormone and adrenaline increases in the body, and this, in turn, reduces the synthesis of testosterone and potency. For several hours after drinking coffee, blood flow to the testicles decreases.

Note: It is important for men not to drink coffee five hours before bedtime. This is due to the fact that the synthesis of testosterone occurs during deep sleep, if under the influence of caffeine sleep is disturbed, respectively, there are failures in the production of the male hormone.

Calorie content and types of product

For those who are on a diet, the important question is how many calories are in instant coffee and its dietary qualities. home useful characteristic instant coffee, which is actively used in dietetics, is the calorie content of the product. The fact is that one cup of coffee without sugar contains almost zero calories (5-10 kcal) and regular use activates metabolic processes in the body. That is why the drink is included in many systems. diet food. It should be borne in mind that the calorie content of a drink with sugar is much higher and dietary products this coffee does not apply.

You can read about how to choose the best instant coffee.

Note: real coffee lovers can buy the product in bags weighing up to 25 kg.

The most expensive and high quality is the sublimated type of instant coffee. The product can be recognized by specific, shiny flattened granules. It preserves all the qualities and properties of the original raw material - grains. Such coffee is the most expensive and its production is fundamentally different from the technology for making other types of drink. First, the grains are ground to a state of flour, then they are frozen together with water and, using special devices, the product is separated from the liquid. Finished plates are ground again.

Powdered product is the cheapest. Granular has the least pronounced aroma and taste.

But more and more often there is a statement that those who want to have a healthy color of the skin and teeth are better off refusing to consume this product. Also, the emphasis is on the fact that instant coffee has more negative impact on the body than the natural analogue, which has a number of advantages.

Benefit

The topic of usefulness of an instant drink is very controversial, according to some reports, it has an antioxidant and vasodilating effect.

Coffee benefits people whose work is related to the thought process, it helps to increase ingenuity.

The data regarding the consumption of the drink with milk are also interesting. Many people find black coffee too bitter, so they find a way out by diluting the drink with milk, as a result of which the taste acquires new shades, becoming more pleasant and soft, and in combination with milk, coffee can relieve heartburn.

In addition, if you often drink black coffee, your teeth get an ugly yellowish coating, when you drink it with milk, the enamel is less stained.

Also, many note that in combination with coffee, the body absorbs milk itself better, because not everyone can drink it separately. Coffee with milk will harm if you drink it in large quantities. But the calorie content of the drink in this case will increase significantly. Especially if you drink it with sugar. If you really want coffee with milk, then you need to use a natural product, and not convenient three-in-one bags. They will not bring benefits, but rather the opposite, harmful components there are a lot of them.

The product is not dietary, it is contraindicated for people who have problems with the gastrointestinal tract. The reaction of the body to the drink is individual and some use it to "start" the work of the stomach and cope with constipation.

Harm

Washing out beneficial substances from the body, the drink contributes to its dehydration, hence the deterioration of the skin condition. Also, due to the intense coloring, it gives the teeth yellowness, and in no case is used during the period of enamel whitening procedures.

If the benefits of natural coffee consumed in small quantities, in the absence of contraindications, are still available, then the soluble analogue of the drink is such positive characteristics does not possess.

In particular, this is due to the fact that the human body functions well only with the constant use of fresh, natural products, instant drink does not belong to this category.

Reasons why you should not get involved in the drink:

• it raises blood pressure;
• washes out useful substances;
• often made from grains of low quality;
• irritates the walls of the stomach.

The insidiousness of the drink is that the negative effect works according to the accumulative system. This means that complications will not appear immediately after a couple of drunk cups, but negative processes start and appear unexpectedly. Instant coffee can lead to both exacerbation of existing ailments and the emergence of new ones.

You can not get involved in coffee and women during pregnancy, especially in the presence of hypertension. Caffeine in large quantities interferes with normal metabolism, and this can lead to the birth of a child with low weight.

It has been proven that in the presence of preservatives, instant coffee has a bad effect on proper metabolism, provoking the appearance of cellulite.

The harm from drinking an instant drink is most pronounced in people who suffer from diseases of the stomach and liver. The fact is that the substances that are added to the composition of coffee are powerful irritants for the gastric mucosa and can provoke the appearance of gastritis and ulcers.

Good afternoon, dear readers! Who doesn't like to pamper themselves in the morning with a cup of fragrant and invigorating coffee. abundance instant drinks on the shelves of shops, allows you to save your time. No need to grind and cook grains, just put a spoonful of granules or powder and pour boiling water.

But is instant coffee really useful - an instant drink. To clarify all the nuances, it is necessary to consider the composition of instant coffee, its types, as well as the method of manufacture. Today in the article, instant coffee benefits and harms, questions about beneficial effect to his health harmful influence and contraindications.

The benefits and harms of instant coffee

For the production of an instant drink, manufacturers use grains that do not have presentation(color, shape), which are sometimes called an illiquid product. Although this does not affect the chemical composition and useful properties.

Chemical composition and active substances of grains

The unique chemical composition of coffee beans is due to more than 1000 elements contained in them, which affect not only the quality of the drink, but also give it taste and aroma.

Heat treatment of grain leads to a change in its quality characteristics. In addition, manufacturers increase the aromatic and taste characteristics of the drink with the help of:

• oils from coffee bean or their synthetic analogues;
• preservatives;
• stabilizers;
• carbonic acid;
• dyes.

A high-quality instant product is made on the basis of the main component - coffee extract, which should be indicated on the package. Otherwise, numerous additives may be included in the product. In some cases, their content reaches 80%.

The main ingredients of coffee are:

• Caffeine. Belongs to the class of alkaloids and is a bitter whitish or colorless crystals. IN different varieties coffee, its amount is different and averages 1.18%. Roasting practically does not change its percentage, which after processing is 1.05%;
• Squirrels. Almost all common varieties of the product (Arabica, Robusta, Liberica, etc.) contain the same number protein substances - up to 13%;
• Carbohydrates. Carbohydrates in coffee beans make up more than 50% of their total weight. The amount of sucrose ranges from 6 to 10%, cellulose - from 5 to 12%, pectin substances– from 2 to 3%. The grains also contain arabinogalactan, galactose, mannose, arabinose, fructose, glucose, etc.

Heat treatment leads to profound changes in the composition of carbohydrates. So in instant coffee, glucose is contained in an amount of 1.25%, fructose - 1.1%, arabinose - 0.15%, galactose - 0.1%. The roasting process leads to caramelization of some types of sugars, which causes the brown color of the product;

• Tannin. The raw product contains 3.6-7.7%. However, roasting reduces it to 0.5–1.0%;
• chlorogenic acids. Represented in the crude product by ten compounds and make up about 10%. When roasted, they participate in various reactions and undergo thermal destruction, which leads to a decrease in their number by about 2 times.

The content of multivitamins and heterocyclic alkaloids (theophylline, glucoside, theobromine, trigonelline and nicotinic acid) is observed. Watch the video, instant coffee from Galileo:

The nutritional value product is directly dependent on its type. On average, 100 g of coffee contains: 0.2 g of proteins; 0.6 g fat; 0.1 g of carbohydrates; up to 5 mg calcium; 0.6 mg of vitamin B3; 9 mg potassium; 7 mg phosphorus; 2 mg iron.

Types of instant coffee, what is their difference

The inventor of the instant drink is the Japanese scientist Satori Kato, who lived in America. The discovery dates back to 1901. The production of the drink was put on an industrial basis in 1906 by the English chemist George Constant Washington.

However, World War II brought popularity to the product, during which both military personnel and civilians liked the quick and convenient preparation of the drink.

At the moment, the sales volume of instant drink is in second place after oil. For industrial purposes, two varieties of coffee trees are grown - Arabica and Robusta.

The modern food industry presents several types of instant coffee, which differ in the method of production and, as a result, in their taste and effect on the body.

Initially, coffee beans are roasted, ground and boiled for several hours using sealed vessels until a thick coffee syrup. Further, the cooking technology is different.

• Powdery. It is the oldest, cheapest and most common of all types of instant drinks. After brewing, the coffee syrup is cooled and filtered. To obtain fine powdery grains, the extract is exposed to hot air, which leads to the evaporation of the liquid.

It is made from leftover raw materials or low-quality grains, contains no more than 5% caffeine, numerous additives and is not of good quality. However, the drink has an acceptable pricing policy, which makes it popular.

• Granulated. Its production is different from powdered final stage, during which grains under the influence of hot steam treatment stick together and are converted into granules.

Such processing of grains leads to a deterioration in the aroma and taste of the drink, but makes it more saturated color and good solubility. Granules contain more caffeine than powder, giving it an advantage over powder. in quality granulated coffee visible impurities are absent, brown granules do not stick together.

• Sublimated. Manufactured using technology different from the above. The coffee concentrate obtained during brewing is instantly frozen and dried in vacuum, bypassing the transition to liquid state. Evaporation of water occurs and the formation of dry matter, which subsequently crumbles into small granules.

This technology is quite long and expensive, but the quality of raw materials is not always high enough.

Freeze-dried coffee has a color, taste and aroma that does not differ from freshly brewed coffee. The beneficial substances contained in coffee beans are not lost during processing. The price of the sublimated version is 30-50% higher than the granulated and powdered version, but taste qualities drink fully justifies it.

The good quality of the sublimated product is evidenced by light brown large granules with a dense texture. They dissolve in water in a short period of time with the formation of a thin white film. The powder found at the bottom of the package indicates poor quality.

On the beneficial and harmful effects on health

Until now, experts have not come to an unambiguous conclusion about the health benefits and harms of instant coffee. The drink has a dual effect on the body, which leads to the need to analyze its properties.

How does it affect the nervous system

The use of instant coffee contributes to an increase in brain activity by an average of 10%, thanks to the natural psycho-stimulant caffeine contained in it. The ingredient provokes the expansion of cerebral vessels, which significantly accelerates blood circulation and some biochemical processes.

Acceleration of the transmission of nerve impulses through neurons increases nervous excitability and, as a result, causes cheerfulness, energy, and increased attentiveness.

The benefits of the drink are undeniable for intense mental activity, long-term driving, as well as for people over the age of 50. It helps to increase attention and reaction, stress resistance and performance. Able to improve mood and eliminate depression (due to the property of the product to stimulate the production of serotonin, the "hormone of happiness" in the body).

The property of the drink to relieve headaches (except for pain in hypertension) is a scientifically proven fact.

However, an overdose can lead to nervous exhaustion and overexcitation, tremors of the limbs and other unpleasant symptoms. In addition, the emergence of addiction, which is similar in strength to alcohol or nicotine, requires a careful approach to the amount of drink drunk.

How does it affect the digestive system

The product in its composition contains organic acids (malic, citric, oxalic, chlorogenic, etc.), which stimulate the production of gastric secretion, which in turn leads to an acceleration of the digestion process. This property is positive, however, in the presence of stomach ulcers, gastritis, pancreatitis and other diseases, it can lead to their exacerbation.

With the abuse of alcohol, coffee prevents the occurrence of cirrhosis. The tannins contained in the product saturate the body with vitamin P and activate metabolic processes with the participation of vitamin C. The tannic properties of tannins make it possible to use a coffee drink for treatment peptic ulcer stomach. Tannins impart a bitter taste to the drink, which can be eliminated by drinking coffee with milk.

How do the heart and blood vessels react to coffee

The product contains numerous components that affect the cardiovascular system. The use of a drink in large quantities leads to a short-term increase blood pressure and to tachycardia.

This property can bring irreparable harm in diseases of the heart and blood vessels. However, it should be noted positive product on the vessels. Reasonable doses of the drink helps to strengthen the vascular walls and improve microcirculation.

Some facts about harm to the body

Soluble types of coffee contain more acids in their composition compared to natural (grain). So they contain about 5.800 g of amino acids and 0.418 g of fat per 100 g of powder. It affects the increase in the acidity of gastric juice, heartburn-causing, in addition, they negatively affect the health of the teeth, thinning tooth enamel. Evidence of this is the increased sensitivity of the teeth to hot and cold, to sour.

Coffee with milk. Coffee with milk helps to reduce the impact of acids on the teeth, since milk has an alkaline environment, which to some extent smooths out the aggressiveness of acids. Add to ready drink you can not only cow, but also, which will reduce:

• coffee acidity,
• its destructive effect on tooth enamel,
• reduce the risk of heartburn
• reduce tooth staining.

Manufacturers in the process of technology add dyes to all types of instant coffee so that its color matches the natural one. Even the most expensive freeze-dried coffee contains a proportion of dyes that affect the whiteness of teeth. In this regard, coffee with milk somewhat protects the teeth from the deposition of dyes on the enamel. But in any case, experts recommend brushing your teeth after a cup of coffee.

There is a risk of harm from excessive coffee consumption, in other cases, even a single overdose of coffee drinks can lead to:

• increased heartbeat;
• dizziness;
• weaknesses;
• nausea;
• decreased clarity of vision;
• loss of consciousness or orientation.

These symptoms may occur when consuming a product with at least 600 mg of caffeine, which causes an overabundance of adrenaline and high blood pressure on the vessels.

Numerous studies show that the systematic use of a drink in large quantities cannot contribute to the occurrence of diseases, but can lead to an exacerbation of chronic pathologies.

When drinking a drink, care should be taken when:

• chronic diseases of the cardiovascular system and pancreas;
• during pregnancy and lactation;
• regular psychological overload, in order to avoid excessive excitation of the nervous system.

Coffee for women and men

For the more vulnerable and sensitive female body Even 3 cups of coffee a day will have a tangible effect:

• reduce the risk of ovarian cancer by 20%;
• eliminate headache caused by weather changes or pressure fluctuations.

The use of the drink during pregnancy is a controversial issue. An increase in the tone of the muscles of the uterus caused by a drink can lead to premature birth. On the other hand, its moderate consumption prevents the risk of fetal death.

Experts still cannot come to an unambiguous opinion about the impact of coffee drink on men. Some of them believe that as a result of its excessive use in the body of the stronger sex, the female hormone, estrogen, accumulates, which negatively affects potency.

Other scientists have the exact opposite opinion. Their argument is based on the stimulating effect of the product and, as a result, an increase in sperm motility, which leads to the activation of sexual desire and an increase in the likelihood of fertilization.

For the elderly, moderate coffee consumption in the absence of contraindications reduces the risk of sclerosis and reduced thinking functions.

The widespread opinion about the benefits of coffee for weight loss is not based on sufficient evidence. Indeed, it improves metabolic processes, but does not contain ingredients that burn fat. For the figure, the benefits of the drink appear only against the background of active physical exercises.
