Is there phosphoric acid in Pepsi? In popular culture

Story

In August 1978, a bottling shop in Evpatoria started operating. The opening ceremony was attended by American businessman Armand Hammer.

In 1979, the mass sale of Pepsi began in 73 branded kiosks in Moscow. Each of them daily sold an average of 4,000 bottles of 0.33 liters, at a price of 45 kopecks apiece. The company sought to build up its visual presence in the city, which hosted the 1980 Summer Olympics, of which the Coca-Cola Company is one of its traditional sponsors. According to the US-Soviet agreements, PepsiCo was the exclusive producer of cola in the USSR, so only imported Coca-Cola was sold at the Olympic events. However, the Coca-Cola Company was able to somewhat push the competitor's position by launching production in the USSR for the Olympics. orange drink"Fanta".

By the early 1980s, 15 million cases of Pepsi-Cola worth $182.5 million were produced annually in the USSR.

On February 6, 1981, the production of the drink was launched in Novosibirsk. Later, during the 1980s, the number of Pepsi bottling shops in the USSR increased to 26.

In 1986, Pepsi became a sponsor of the Goodwill Games.

On May 17-21, 1988, commercials paid for by a Western manufacturer were shown on Soviet television for the first time - PepsiCo acquired the right to show four clips in prime time (two of them featured Michael Jackson).

Pepsi Cola in Russia

Opening of Pepsi bottling plants in Russian cities:

Music

"Pepsi" in Russian-language music:

• The Zoo group has a composition called Rum and Pepsi-Cola. The author of the song is Mike Naumenko. A recording of an apartment concert is also known, where Mike Naumenko performs this song together with Viktor Tsoi. In 2000, this song was remake by Dmitry Dibrov;
• In the song of the Russian chanson performer Sergey Trofimov, “Pepsi Generation”, a picture of the worldview of young people and the previous generation of Russians, who sing of the “Western” way of life, is shown;
• "Suburban Blues No. 2" by the group "Zoo";
• "Boys of the 80s" by Dmitry Dahl;
• "Girls love pilots" of the Center group.
• "Rom i kola" by Padla Bear Outfit.

During the filming of a video for the Pepsi company (on the night of 01/27/1984), Michael Jackson suffered: Jackson's hair caught fire from the fireworks and the singer received serious burns. He received 20 stitches. Filming took place in 1984 in Los Angeles. Later, the artist himself confirmed this incident, saying that in his entire life he had done only two plastic surgeries, one of which was skin grafting after these burns.

Cinema

The mention of a drink, bottles, cans or advertising banners can be seen or heard in such films and cartoons as: " The end of the holidays", "Needle", "Vacation in Prostokvashino", "Interception", "Back to the future". In the 1979 Soviet film “Foam” (directed by A. Stefanovich, script by S. Mikhalkov), the character Poludushkin (Rolan Bykov) brings Makhonin (Anatoly Papanov) a box of Pepsi-Cola, which Makhonin loves in the story. The very name of the film "Foam" has a certain allusion to the foam of "Pepsi-Cola".

Health impact

The press often raises questions about whether the use of Pepsi-Cola is completely safe for health and whether this drink can be a complete element of the diet healthy person. No specific negative effect of Pepsi-Cola on the body has been officially established; The effect of the drink on health does not differ from that for similar products:

• it is not recommended to drink highly carbonated drinks to persons suffering from diseases of the gastrointestinal tract, in particular, acute and chronic gastritis, including those accompanied by increased gastric secretion, peptic ulcer of the stomach and duodenum, disorders of the biliary tract, diseases of the pancreas and other pathological processes;
• carbonated water causes indigestion and can lead to pancreatitis if consumed continuously.
• excessive intake of phosphoric acid in the body can cause calcium deficiency and urolithiasis;
• with prolonged use of Pepsi-Cola, an allergy to its components (including urticaria) may appear, which lasts up to 4 weeks, as it is aggravated by the lack necessary norm calcium in the body.

In January 2011, 4-methylimidazole, found in caramel coloring, was listed as a possible carcinogen in California, indicating that 16 micrograms per day of the substance was of no significant hazard. The indicated amount of the substance is much less than the average intake of the body when consuming Pepsi. The food industry opposed the decision, pointing out the need for additional warnings on many products, and also questioned the validity of these data.

In March 2012, Coca-Cola and Pepsi announced changes in the production of caramel colors: in order to comply with the new California standards, drinks sold in California already meet the new requirements. As of March 2012, the method of making caramel colors used in Europe has not changed, the content of 4-methylimidazole remains at the same level.

Possible composition of the drink

Drink in a glass

The original recipe for Pepsi-Cola, brought to court in the United States when the company filed for bankruptcy in 1923.

If you convert to the metric system, it will be something like this:

Stir for 2 hours, boil water with sugar beforehand.

Petitgrain Lemon Oil is obtained from the leaves and twigs of the lemon tree. The drink originally contained the enzyme pepsin, which aids in digestion. Like Coca-Cola, Pepsi was first sold with still water, and probably contained gum arabic as an emulsifier.

Pepsi is widely known for its commercials. They starred in Pepsi commercials.

Millions of people daily drink millions of liters of dark fizzy drink with bubbles, without thinking about what is poured into bottles with bright labels ...

Here are a couple of quotes from the official website of Coca-Cola in Russia (www. cocacola. ru):

- “More than 162 million liters are consumed daily in the world Coca- Colaand 84 million liters of other Company drinks.”

-“ Coca-Cola recognized as the "People's Brand" in 2002 according to the results of a survey of the population of Russia. This is a nationwide recognition of Russians for a drink Coca-Cola.”

According to the results of studies by German scientists, in the bones of young people who often drink sweet soft drinks, there is a reduced content of minerals strengthening the skeleton.

The results of the scientific work were published in the American Journal of Clinical Nutrition. German scientists have been studying the food preferences of children and young people since 1985. Participants in the study undergo computed tomography and take tests that determine the level of mineral content in the bones. These data are studied in relation to the volumes of consumption. soft drinks.

"The more sugary soft drinks young people drink, the less minerals they have in their bones," sums up study leader Professor Thomas Römer. Those who quench their thirst mainly with cola or fruit lemonade get less protein on average.

A kilogram of synthetics replaces a ton of natural sugar, so it is not surprising that saccharin tablets are gradually replacing sugar from the confectionery field. Saccharin 300 times sweeter than sugar and much cheaper and, of course, it would be more profitable for the manufacturer to purchase cheap saccharin than sugar, because the issue of people's health is not considered during production, but only the issue of the greatest profit.

This is, firstly, a direct path to obesity, since it is impossible to get enough of such food and the feeling of hunger comes very quickly. Secondly, this is how putrefactive processes begin in the intestines, because there was no normal digestion as such. By the way, this is the way in which "McDonald's" and made a lot of money. Washing down food (sandwiches, hamburgers, hot dogs) with ice drinks, a person will never be able to eat fast food, which means that he will come to eat again and again. At the same time, hot drinks - tea, coffee - are set at a rather high price and they are not included in complex sets, but ice-cold Coca-Cola is relatively cheap. From the above, we can conclude: to avoid digestive problems, never drink cold drinks with food!

So, taking warm Cola-Light leads to the disintegration of aspartame into very harmful components, taking cold Cola causes an instant exit from the stomach of undigested food.

A joint group of physicians from several Western countries studied the properties of various drinks, known under the name "Cola" - Pepsi-Cola, Coca-Cola, etc. And according to the results of the research, these doctors came to very disappointing conclusions.

It turned out that long-term use of cola leads to impotence in men and infertility in women. Naturally, there are exceptions, but they only confirm the rule. Such a sad effect is caused by a nut - cola, which is used in the manufacture of drinks.

Once upon a time, this nut grew only in America and was given to chew by Indian warriors - for about the same purpose for which bromine is used in the current army: to reduce potency, completely calm all sexual instincts, which does not allow soldiers or soldiers to be distracted from service.

To throw Coca Cola on Turkish market, the owners of the concern had to publish the full recipe for the drink, inincluding the famous secret ingredient. Themturned out to be a food additive carminic acid, produced fromcochineal. If you not yet in course, several species of insects of different families of the coccid suborder are called cochineal. Theirfemales are used to produce carmine, in other words, red dye. Previously, carmine was widely used intextile industry, and then he fell in love with the food industry - withit is used to color dairy products and sweets, which the consumer is ready to perceive only inred-pink colors.

The Coca-Cola concern, which absolutely legally sells around the world a weak solution of the drug cocaine under the name "Coca-Cola", was sued in connection with the presence in Coca-Cola of a substance that causes blood cancer - leukemia. This substance is called benzene. In this perverted Western society of drug addicts, you can’t just sue a concern for selling a weak solution of cocaine - you have to sue for the presence of benzene, but for the presence of cocaine in a drink for children, you see, you can’t !!! Any chemist knows the recipe for Coca-Cola simply from general considerations. Firstly, they themselves say that the recipe is made from the Kola plant, from which the drug cocaine is made. That is, Coca and Pepsi Cola - this is fundamentally - a weak solution of the drug Cocaine !!!

Indian NGO Center for Science and Environment (CSE ) published the results of its research, according to which in drinks bottled Coca-Cola in India, the level of pesticides is 30 times higher than the norms adopted in the EU, and in the Indian Pepsi - 36 times. According to the report CSE , in drinks produced by companies Pepsi and Coca-Cola in India, toxic substances such as DDT, lindane and chlorpyrifos were discovered. According to journalists BBC (after conducting its own investigation), produced as a by-product in one of the Indian factories Coca-Cola the fertilizer, which is then sold to local farmers, contains a powerful carcinogen, cadmium.

The active ingredient in Coca-Cola is phosphoric acid. Its pH is 2.8. For the transport of concentrate Coca-Cola the truck must be equipped with special containers designed for highly corrosive materials.

1. Aquacarbonated- sparkling water

The presence of carbon dioxide in water stimulates gastric secretion, increases the acidity of gastric juice and provokes flatulence - profuse gas. In addition, not spring water is used, but tap water, passed through special filters.

2 . E952 ( CyclamicacidandNa, K, Casalts, Cyclamic acid and its sodium, potassium and calcium salts).

Sugar substitute. Cyclamate - petroleum-based synthetic substance, 200 times sweeter than sugar, carcinogen, causes cancer used as an artificial sweetener. It has been banned from use in human food because it is a carcinogen that causes cancer. In 1969, by order of the Federal Agency for Food Products and medicines ( FDA ) is prohibited for use in the United States, t.to. like saccharin and aspartame, it has been shown to cause cancer in rats Bladder. Banned in Canada the same year. Banned in Japan, South Korea and Singapore in 1975. And in Indonesia, which supplies cyclamate to Russia, it is also banned. However, in Russia, 70% of all sweeteners are cyclamate, modestly referred to as part of carbonated water - K-952. It is imported into the country at 1,000 tons per year, because it is very cheap and has no limited shelf life (after all, 300 years cannot be considered a temporary limitation). During World War II, cyclamate, among other cheap products, was supplied to concentration camps.

3. E150d (Caramel IV - Ammonia-sulphite process, dye)

– sugar color 4 obtained by “ammonia-sulfite” technology ( CARAMEL 4 – Ammonia - sulphite ). That is, sugar color ( burnt sugar) is obtained by processing sugar at certain temperatures with or without the addition of chemicals. IN this case add ammonium sulfate.

4. E950 ( AcesulfamePotassium, acesulfame potassium)

200 times sweeter than sucrose. A mixture of acesulfame potassium and aspartame is widely used in soft drinks. Contains methyl ester, which impairs performance of cardio-vascular system, and asparogenic acid, which has a stimulating effect on nervous system and may, over time, become addictive. Acesulfame is poorly soluble.

5. E951 ( Aspartame)

Sweetener. Chemically unstable: when the temperature rises, it decomposes into methanol and phenylalanine. methanol ( methyl alcohol) is very dangerous: 5-10 ml can lead to death of the optic nerve and irreversible blindness, 30 ml can lead to death. In warm soda and aspartame is transformed into formaldehyde, which is the strongest carcinogen. Aspartame (aka: sweetly, slastilin, sukrazid, nutrisvit) provokes headaches, fatigue, palpitations, depression. Cancer does not cause, but brain tumor and tuberculosis in some cases provokes.

National Soft Drink Association ( NSDA ), representing 95% of the soft drink companies in the US, constituted a protest published in the Congressional Report on May 7, 1985, describing the chemical instability of aspartame. After weeks in a hot climate (or being heated to 30 degrees Celsius (86 Fahrenheit), the main amount of aspartame in sparkling water decomposes into formaldehyde, methanol, phenylalanine, etc. Swallowed, methanol (the methyl or wood alcohol that killed or blinded thousands of drinkers) is converted to formaldehyde, then to formic acid (ant sting poison).

6. E338 ( Orthophosphoricacid, orthophosphoric acid) - chemical formula: H3 PO4 .

Introduction

Human health largely depends on lifestyle, and therefore on what we eat and drink. If you pay attention to what people quench their thirst with or drink sandwiches, buns, then most often children and adults will see a glass or a bottle with a carbonated drink in their hands. With what more often? Cola is one of the most popular drinks in our country. Advertising convinces consumers that these drinks are the best for quenching thirst, with some advertisers claiming that Pepsi-Cola does it better and others claiming that Coca-Cola does it better. But in Lately due to the widespread use of preservatives, dyes and artificial flavor additives In the food industry, there are more and more calls for people to stop consuming Coke, explaining that the composition of these carbonated drinks is extremely harmful. Many parents try to restrict their children from drinking these drinks. But sometimes it is very difficult to convince children. After all, Cola is so great - the advertisement says! And people, especially children, fall for these tricks. For several years now, the sale of any carbonated drinks has been prohibited in the cafeteria of our school. Why? In the course of my work, I will try to explore the composition and properties of Coca-Cola and Pepsi-Cola, how they differ and what is the effect of their impact on our body.

Before the study, I conducted a survey among school students (Appendix 3). It was attended by 30 people from 2nd to 11th grade. It turned out that most of the guys prefer carbonated drinks, considering them tasty. This fact convinced me of the relevance of the study.

Object of study:carbonated drinks « Coca-Cola and Pepsi-Cola.Subject of study:composition, properties and influence of "Coca-Cola" and "Pepsi-Cola" on the human body.

Target: to study and compare the composition, to investigate the properties and influence of "Coca-Cola" and "Pepsi-Cola" on the human body.

Job hypothesis:carbonated drinks "Coca-Cola" and "Pepsi-Cola" are equally unhealthy.

In carrying out this research work, the following tasks:

To study and analyze information on the issue of research in the scientific literature and Internet sources on the composition of drinks and their effect on the human body;

Conduct a survey among students of MBOU secondary school with UIOP No. 183 named after R. Alekseev and analyze the results;

Conduct an experiment to study the properties of Coca-Cola and Pepsi-Cola;

Based on the experiment, compare drinks in terms of composition, properties (physical, chemical, organoleptic) and the effect of these drinks on the human body;

Research methods:work with information sources, Internet resources; questioning; experiment: observation; comparison;

analysis and generalization of information.

CHAPTER 1 Characteristics of drinks "Coca-Cola" and "Pepsi-Cola"

1. History of drinks

Coca-Cola drink was invented in Atlanta on May 8, 1886. Its author is pharmacist John Steve Pemberton. The name for the new drink was coined by Pemberton's accountant Frank Robinson, who also, mastering calligraphy, wrote the words "Coca-Cola" in beautiful curly letters, which are still the logo of the drink. Coca-Cola was an exotic patented drug "for any nervous disorder" and began to be sold through a machine in Jacob's largest drugstore in Atlanta, first in the form of syrup. It contained cocaine from coca leaves and caffeine from kola nuts (3:1). Coca leaves were a favorite drug of the Indians of Bolivia, who chewed them while working. From the same leaves in 1859, Albert Niemann isolated a special component (drug) and named it cocaine. At that time, cocaine was not a banned substance and nothing was known about its harm to health. Therefore, cocaine was freely sold and was often added to drinks for pleasure and tone. Soon, pharmacy salespeople began to mix the syrup with sparkling water. This is how Coca-Cola was born.

"Pepsi Cola" - non-alcoholic soft drink. The drink was first made in the 1890s in New Bern by pharmacist Caleb Bradham. At first, the drink was called "Brad'sdrink", but on August 28, 1898 it was renamed Pepsi-Cola. In the USSR, Pepsi-Cola was first sold by supplies from the USA (April 1973), and then the construction of factories for the production of Pepsi-Cola began. WhileNovosibirsk Pivvinkombinat (new name "Vinap ”) produced Pepsi-Cola according tolicenses called Pepsi. After the end of the license, he began to produce his "Vinap-Cola» . If you look deeply into the history of the struggle between Pepsi-Cola and Coca-Cola for leadership in the sales market, we can conclude that the history of these drinks and their composition are largely similar.

1. Chemical composition

Since the purpose of my work is to study and compare the chemical composition of Coca-Cola and Pepsi-Cola carbonated drinks, I must know the components of drinks.

Examining the information indicated on the label of Coca-Cola and Pepsi-Cola, I established the presence of:

The composition of drinks

Ingredients of Coca-Cola	The composition of "Pepsi-Cola"
Purified carbonated water	Water
Sugar	Sugar
Natural dye sugar color 4	Dye E150a
Acidity regulator phosphoric acid	Acidity regulator E338
natural flavors	Natural Pepsi Flavors
Caffeine	Caffeine no more than 110mg/l
	CO 2 gas

Various additives are used in the production of these drinks. Substances that can be used by various manufacturers in the manufacture of Coca-Cola and Pepsi-Cola are presented in Appendix No. 2

Nutritional value of Coca-Cola and Pepsi-Cola per 100 ml

Index	"Coca Cola"	"Pepsi Cola"
Calorie content, kcal
Proteins, g
Fats, g
Carbohydrates, g	10,6	10,8
Total sugars, g	10,6

Based on the foregoing, we can draw conclusions: the difference in the composition of Coca-Cola and Pepsi-Cola is insignificant, which allows us to assert that there is no fundamental difference when choosing one of these drinks.

For the production of Coca-Cola and Pepsi-Cola, a large amount of synthetic substances in the form of E-additives are used, which are harmful to our body. I want to note that the composition of each of the studied drinks includes caffeine, which has an exciting effect on the central nervous system and a fairly large amount of carbonic, orthophosphoric, citric acids.An analysis of the literature data showed the following: The history of Coca-Cola and Pepsi-Cola began in the second half of the 19th century. All these years, there has been a constant “war” between them for sales markets, for the buyer, i.e. us with you! Held analysis of organoleptic and physical and chemical properties showed:

- organoleptically, both drinks are similar;

The composition of carbonated drinks includes acids, the content of which is quite high, so drinks sour taste, which can cause a number of diseases; therefore, they should be used in moderation;

Cola drinks contain ingredients that cause various diseases.

Thus, it can be assumed thatthe studied drinks are harmful, as they are aggressive towards plant and animal cells!

The survey showed that carbonated drinks are very popular among the students of our school: 87% of respondents respect them. Most students think harmful use these carbonated drinks, but they drink them anyway. The reason is the poor awareness of the guys about the properties of Cola and the power of advertising. So is it possible to avoid the negative effects of Pepsi-Cola and Coca-Cola on the human body.If you ask any person what he loves more, Coca-Cola or Pepsi, then the answer will be given unequivocally, either one or the other. Do you think it's a matter of taste? Of course not. Scientists say that a person is not able to distinguish a glass of Pepsi from the same glass of Coca-Cola. No color, no taste, no smell. Preference for any of these drinks gives our brain, but not our receptors. That is, it all depends on the strength of the brand and advertising company. Just like all carbonated drinks, Colas contain dyes, acidity regulators, preservatives and other additives. So they are just harmful to health.Both drinks are harmful to us as food.Through research, I realized that it is better to use homemade drinks to quench my thirst, natural juices or mineral water without gas.

CHAPTER 2 Evaluation of indicators in identifying the quality of drinks

2.1. Evaluation of drinks by organoleptic indicators

For research, two samples of carbonated drinks were selected:

1. non-alcoholic highly carbonated drink "Pepsi-Cola", flavored. Volume 1.25 l.

2. "Coca-Cola" - a highly carbonated soft drink. No preservatives natural dye caramel. Volume 1 l.

When identifying the quality of drinks and comparing them, organoleptic indicators were determined.

Organoleptic methods were used to study: color, taste, saturation of drinks with gas. The study involved 10 students of 8 "B" class.Research results:

1. Studies have shown that both drinks are sweet, but with a sour taste. Unanimous opinion, which of the drinks has more pronounced data taste characteristics, did not have. This difference of opinion may be due to the fact that the perception of taste is individual and very subjective.

2. These drinks are characterized by strong saturation with carbon dioxide (carbonic acid).

2.2. Evaluation of drinks by physical and chemical indicators

For experimental proof harmful effects carbonated drinks on living organisms, I took muscle tissue pork meat and protein chicken egg- animal cells, bean and wheat sprouts - plant cells.

Experience number 1. "The action of drinks on the animal cell". Purpose: to find out the effect of "Coca-Cola" and "Pepsi-Cola" on animal cells.

The effect of drinks on meat cells.

Experimental procedure: I took 3 pieces of meat. I put them in glass bowls. I poured alcohol into one of the samples (for comparison), and added drinks to 2 other meat samples. After a day, the meat began to change its color and a loose, flaky sediment appeared in the samples with drinks. On the 4th day, the solutions of Coca-Cola and Pepsi-Cola became lighter, there was more brown sediment, and the meat changed its color to pinkish-white and became covered with a layer of mucus. The meat, which was in alcohol, turned white, but there was no sediment. When I looked at the change in muscle fibers, I observed the following:

1. Meat from alcohol is pale, hard, the fibers are separated from each other without much difficulty (the original object did not have such a property).

2. Meat samples from drinks elongate when stretched, the fibers are easily stretched (become elastic) and separated (Appendix No. 2, photo No. 1-6).

The effect of drinks on egg protein.

Experimental technique: I took 2 eggs and separated the protein. Protein poured into glass cups. I poured alcohol into one of the samples, and added Coca-Cola and Pepsi-Cola to 2 others. The results of the experiment: the protein in alcohol immediately began to denature. Characteristic white lumps appeared. In the other two cups, hen egg protein also denatured, less dense protein clots formed, and, just as in the experiment with meat, loose brown flakes appeared (I assume that it is the components of various additives that are in drinks that precipitate).

Conclusion: similar changes occur in our body with protein molecules in cells when drinking the studied drinks (Appendix No. 2, photo No. 7-10).

Experience number 2. "The effect of drinks on plant cells". Purpose: to find out the effect of "Coca-Cola" and "Pepsi-Cola" on plant cells.

Experimental technique.For this experiment, we took bean and wheat sprouts. The control samples were filled with water, and the experimental samples were filled with Coca-Cola and Pepsi-Cola. Results of the experiment: after two days, I saw that the plants develop well in water, and in the experimental samples I found the following changes: wheat seedlings became pale, the upper part of the leaf began to curl and dry out. Two days later, there was even less chlorophyll (the leaves were even paler) and almost everything in the upper part curled up and withered. I did not find any differences in the effect of Coca-Cola and Pepsi-Cola drinks on wheat. Both drinks inhibit the development of wheat in the same way: the leaves are twisted and withered; yellowish spots first began to appear on the cotyledons and bean leaves, and after 3 days dark spots also appeared. Then the leaves began to dry up. This process was faster in the Pepsi-Cola sample.

Conclusion: since the green color of plants is due to the presence of chlorophyll pigment, I conclude that chemical composition drinks destroys the pigment and, as a result, the biochemical processes of vital activity in plants slow down and the plants die (Appendix No. 2, photo No. 11-16).

For beans, Pepsi-Cola is a more aggressive environment. Therefore, it can be concluded that with the simultaneous use by a person plant food containing chlorophyll, and any of these drinks, destruction occurs organic compounds and lost nutritional value products due to substances contained in Coca-Cola and Pepsi-Cola.

Experience 3. "The action of drinks on rust". Purpose: to prove that it is possible to clean the surface of nails from rust with the help of Coca-Cola and Pepsi-Cola. Experimental technique.For the experiment, Coca-Cola and Pepsi-Cola were poured into chemical beakers and one rusty nail was lowered into them.The result of the experiment.Five days later, the nails were free of rust and were almost like new. The color of the drinks has changed: it has become cloudy - brown due to the ongoing reactions between iron (III) hydroxide and acids.

Conclusion: the composition of drinks contains acids (in a sufficiently high concentration) that interact with rust. Therefore, when daily use any of these drinks, our body is exposed to the same effect of acids (Appendix No. 2, photo No. 17,18).

Experience number 4. "The effect of drinks on tea plaque". Purpose: to find out the effect of Coca-Cola and Pepsi-Cola on tea raid.
Experimental technique.I took 2 tea cups, filled it with strong tea broth and left it for several days. When a persistent plaque appeared on the inner surface of the cups, I poured out the rest of the tea leaves and tried to rinse the plaque. plain water traces of tea plaque were not removed. Then I poured Coca-Cola into one of them, and Pepsi-Cola into the other.

The result of the experiment.Three days later, the tea raid was almost gone. I did not see any difference in the effect of drinks.

Conclusion: Coca-Cola and Pepsi-Cola contain substances that destroy stubborn tea stains, i.e. can act like detergent» (Appendix No. 2, photo No. 19.20)

Experience number 5. "Detection of orthophosphoric acid in beverages". Purpose: to identify the presence of phosphoric acid in the studied carbonated drinks.

Conclusion : both drinks contain phosphoric acid, but Pepsi-Cola has slightly less of it. This experiment mimics the process of "washing out" calcium from bone cells and tooth enamel in our body.(Appendix No. 2, photo No. 21-24).

Experience number 6. "The effect of study beverages on fats". Target:to find out the effect of the studied carbonated drinks on fats. Experimental technique: in three chemical glasses placed a piece butter. I poured the solution into the first glass ethyl alcohol, in the other two - the studied drinks. In a glass of alcohol, a piece of oil sank to the bottom. In glasses with drinks, the pieces turned out to be at the top, which indicates a high density of the solutions. Three days later, I discovered that a piece of oil in alcohol became loose and its partial dissolution occurred. There were no changes in the other two glasses of fat. Conclusion: When drinking the studied drinks, fats are not broken down in our body, which contradicts the prevailing opinion about the use of Coca-Cola and Pepsi-Cola for weight loss.

Availability of sugar substitutesexplored in a simple way: poured drinks on the surface of the table, let it dry a little and touched the place of the spill. The surface of the table became sticky, which indicates the presence of sugar-like substances in the studied drinks (Appendix No. 2, photo No. 28).

. My experiments have shown that both carbonated drinks are unhealthy, as they are artificial products, contain sugar substitutes, many acids and various nutritional supplements that have a negative effect on living cells.

2.3. The effect of drinks on the human body

From the course of chemistry, we know that the composition of a substance determines its properties. In table No. 1 of Appendix No. 1I presented the substances that can be in Cola from different manufacturers. Using these data, I want to consider the effect of each component of the composition of drinks on the human body. 1.Orthophosphoric acid (E338).Acid leaches calcium from bones, dissolves the mineral substances of the enamel, causing the teeth to become fragile, more sensitive and more prone to decay. Drinking these drinks for a long time can lead to tooth decay. Excessive intake of phosphoric acid contained in Pepsi-Cola can cause urolithiasis.

2. Dyes , which are part of coca-cola” and “Pepsi-Cola” are very persistent and darken the teeth from them.

3. Lemon acid. It burns the gastric mucosa, causing a false feeling of lack of water in the body, causing thirst.

4. Carbon dioxide - excites gastric secretion, increases acidity and increases intestinal flatulence. It is not recommended to drink carbonated drinks for people suffering from diseases gastrointestinal tract

5. Carbohydrates. In 0.33 liters of Pepsi-Cola, the sugar content is equal to 8 pieces of refined sugar. Coca-Cola also contains a lot of sugar (about six tablespoons per glass, almost the maximum norm for the human body per day). All these carbohydrates are deposited in the fat folds and contribute to the development of diabetes and obesity.Various sweeteners are added to these drinks to minimize calories. The most dangerous of them is aspartame.It is a synthetic compound containing phenylalanine, which is known to deplete the body of the “happiness hormone” serotonin and cause depression, irritability, anger and panic. Once in the mouth, aspartame molecules remain on the mucous membrane, and saliva can hardly remove them from there; as a result - a feeling of thirst and a new portion of Cola. Aspartamecauses allergies, stomach diseases, liver dysfunction, headaches, weakening of memory and vision, and even seizures. It is sweeteners that are the main secret of sparkling water - they do not quench thirst, but, on the contrary, cause appetite.

Love for "Coca-Cola" and "Pepsi-Cola" leads to potassium deficiency:falling to a dangerous level, it can cause damage to muscle tissue and bring a person to paralysis. Low levels of potassium in the blood are also apathy, muscle weakness and loss of appetite.

6. Sugar color (E150). It is used as a dye to give Coca-Cola color. Naturally, it is created artificially, which does not add a single gram of usefulness to these drinks.What is so intimidating in drinks?

Artificial dye, "caramel" dye contains compounds that adversely affect human health. Exposure to these carcinogens leads to the development of lung cancer, liver cancer, thyroid cancer, and leukemia.You can not drink the studied carbonated drinks chilled, with ice, while drinking them with food, because. this is the first step towards obesity.Drinks "Coca-Cola" and "Pepsi-Cola" are prohibited in educational institutions, because they have a destructive effect on the stomach and liver cells.In addition, Coca-Cola contains caffeine.If you abuse the drink, you can get caffeine addiction. Its signs are anxiety, agitation, insomnia, stomach pains, cramps, tachycardia and a decrease in the overall tone of the body.

Summarizing the above, we can conclude that "Cola" is not a desirable product for the diet and is categorically not recommended for the teenage body.

Conclusion

In carrying out this research work, the following tasks: studied and analyzed information in the scientific literature and Internet sources on the composition of drinks and their effect on the human body;

a survey was conducted among students of MBOU secondary school with UIOP No. 183 named after R. Alekseev and the results were analyzed; an experiment was conducted to study the properties of "Coca-Cola" and "Pepsi-Cola"; on the basis of the experiment, drinks were compared in terms of composition and effect on the human body; conclusions are made based on the results of the study.

The study of literature sources and the study of the composition made it possible to draw the following conclusions:

The chemical composition of drinks destroys the pigment and, as a result, the biochemical processes of life activity in plants slow down and the plants die (Appendix No. 2, photo No. 11-16);

With the simultaneous use by a person of plant foods containing chlorophyll, and any of these drinks, organic compounds are destroyed and the nutritional value of the products is lost due to the substances contained in Coca-Cola and Pepsi-Cola;

The composition of drinks contains acids (in a sufficiently high concentration) that interact with rust. Consequently, with the daily use of any of these drinks, our body is exposed to acids (Appendix No. 2, photos No. 17,18);

- "Coca-Cola" and "Pepsi-Cola" contain substances that destroy persistent tea stains, i.e. can act as a "detergent" (Appendix No. 2, photo No. 19,20);

Both drinks contain phosphoric acid, which provokes the process of "washing out" calcium from bone cells and tooth enamel in our body.(Appendix No. 2, photo No. 21-24);

When drinking the studied drinks, fats are not broken down in our body, which contradicts the prevailing opinion about the use of Coca-Cola and Pepsi-Cola for weight loss.(Appendix No. 2, photo No. 25-27).

Conclusions on the results of the experiment. My experiments have shown that both carbonated drinks are harmful to health, as they are artificial products, contain sugar substitutes, a lot of acids and various food additives that have a negative effect on living cells.

Activity prospects:

As part of the school health program for students in grades 5-11, conduct conversations and cool watch about carbonated drinks "Coca-Cola" and "Pepsi-Cola" and their effect on the human body.

Applications

Application No. 1

Table

The chemical composition of Coca-Cola and Pepsi-Cola.

Ingredients:	Characteristics and effect on the body
Aqua mineral - carbonated water.Carbonic acid	CO 2 - carbonic acid. A must have in any carbonated drink. By itself, it is harmless (it is used to better preserve the drink), but its presence in water excites gastric secretion, increases the acidity of gastric juice and provokes flatulence - profuse gas and the occurrence of gastritis and peptic ulcer.
E952- Cyclamic acid and its salts.	Sugar substitute. Cyclamate- a synthetic substance based on oil, 200 times sweeter than sugar, carcinogen, provokes cancer. Used as an artificial sweetener. Previously referred to substances prohibited for use. But in 1979, WHO rehabilitated cyclamates, recognizing them as harmless. In Russia, 70% of all sweeteners are cyclamate.
E150d - dye - sugar color 4.	Dye - sugar color 4.Sugar color (burnt sugar) is obtained by processing sugar with or without the addition of chemicals. In this case, ammonium sulfate is added.
E950 - acesulfame potassium	Sweetener. Widely used in soft drinksmixture of acesulfame potassium with aspartame. Minuses. Contains methyl ester, which impairs performance of cardio-vascular system, aspartic acid, which has a stimulating effect on the nervous system and addictive, provokes headaches, fatigue, depression. Cancer does not cause, but brain tumor and tuberculosis in some cases provokes. Products with this sweetener are not recommended for children, pregnant and lactating women.
E951 - aspartame	Aspartame - sweetener for diabetics chewing gums. Recommended for people who control their weight. Some experts note the chemical instability of aspartame. If the substance is at a temperature of about 30 degrees, then the main amount of aspartame in carbonated water decomposes into formaldehyde, methanol, phenylalanine, etc. Swallowed, methanol is converted into formaldehyde, then into formic acid (ant sting poison). Formaldehyde - it is a substance with a pungent odor, carcinogen class A. During pregnancy, aspartame can affect the fetus directly, even when consumed in very small doses. It causes the following diseases: brain tumor, sclerosis, epilepsy, Graves' disease, chronic fatigue, Parkinson's and Alzheimer's diseases, diabetes, mental retardation, tuberculosis, etc.
E338 - phosphoric acid - chemical formula H 3 PO 4	Acidifier. Food phosphoric acid is used in the production of carbonated water and to obtain salts (powders for making cookies, crackers). Orthophosphoric acid - has a toxic effect on the kidneys, liver and nerve cells, “washes out” calcium (the cause of bone fragility), destroys tooth enamel.
E330 - lemon acid - experience	Acidity regulator, used to impart a pleasant sour taste.Citric acid, although weak, can cause significant harm to the body, primarily by destroying tooth enamel and disrupting the acid balance of the stomach,while causing a false sense of lack of water in the body, simply put - thirst.
Aromas	Aromatic additiveswhich ones are not specified.
E210- benzoic acid E211 - sodium benzoate	food preservative. Introduced into some foods, as a bactericidal and antifungal agent. Products containing sodium and calcium benzoates are not recommended for asthmatics and people sensitive to aspirin.
Tartrazine, Quinoline Yellow, Sunset Yellow, Azorubine, Erythrosin, Red 2G and so on.	Food colorings.All of them, contrary to what is written on the labels, are not "identical to natural", but are obtained by chemists in the laboratory.
Caffeine	Under the influence of caffeine, cardiac activity is accelerated, blood pressure, for about 40 minutes, the mood slightly improves due to the release of dopamine, but after 3-6 hours the effect of caffeine disappears: fatigue, lethargy, and decreased ability to work appear. Caffeine, like other CNS stimulants, is contraindicated in hyperexcitability, insomnia, severe hypertension and atherosclerosis, in organic diseases of the cardiovascular system, in old age, and in glaucoma.

Millions of people daily drink millions of liters of dark fizzy drink with bubbles, without thinking about what is poured into bottles with bright labels ...

Here are a couple of quotes from the official website of Coca-Cola in Russia (www. cocacola. ru):

- “More than 162 million liters are consumed daily in the world Coca- Colaand 84 million liters of other Company drinks.”

-“ Coca-Cola recognized as the "People's Brand" in 2002 according to the results of a survey of the population of Russia. This is a nationwide recognition of Russians for a drink Coca-Cola.”

According to the results of research by German scientists, in the bones of young people who often drink sweet soft drinks, there is a reduced content of minerals that strengthen the skeleton.

The results of the scientific work were published in the American Journal of Clinical Nutrition. German scientists have been studying the food preferences of children and young people since 1985. Participants in the study undergo computed tomography and take tests that determine the level of mineral content in the bones. These data are studied in relation to the volumes of consumption of soft drinks.

"The more sugary soft drinks young people drink, the less minerals they have in their bones," sums up study leader Professor Thomas Römer. Those who quench their thirst mainly with cola or fruit lemonade get less protein on average.

A kilogram of synthetics replaces a ton of natural sugar, so it is not surprising that saccharin tablets are gradually replacing sugar from the confectionery field. Saccharin is 300 times sweeter than sugar and much cheaper, and of course, it would be more profitable for the manufacturer to purchase cheap saccharin than sugar, because the issue of human health is not considered during production, but only the issue of the greatest profit.

This is, firstly, a direct path to obesity, since it is impossible to get enough of such food and the feeling of hunger comes very quickly. Secondly, this is how putrefactive processes begin in the intestines, because there was no normal digestion as such. By the way, this is the way in which "McDonald's" and made a lot of money. Washing down food (sandwiches, hamburgers, hot dogs) with ice drinks, a person will never be able to eat fast food, which means that he will come to eat again and again. At the same time, hot drinks - tea, coffee - are set at a rather high price and they are not included in complex sets, but ice-cold Coca-Cola is relatively cheap. From the above, we can conclude: to avoid digestive problems, never drink cold drinks with food!

So, taking warm Cola-Light leads to the disintegration of aspartame into very harmful components, taking cold Cola causes an instant exit from the stomach of undigested food.

A joint group of doctors from several Western countries studied the properties of various drinks known as "Cola" - Pepsi-Cola, Coca-Cola, etc. for several years. And as a result of the research, these doctors came to very disappointing conclusions.

It turned out that long-term use of cola leads to impotence in men and infertility in women. Naturally, there are exceptions, but they only confirm the rule. Such a sad effect is caused by a nut - cola, which is used in the manufacture of drinks.

Once upon a time, this nut grew only in America and was given to chew by Indian warriors - for about the same purpose for which bromine is used in the current army: to reduce potency, completely calm all sexual instincts, which does not allow soldiers or soldiers to be distracted from service.

To throw Coca Cola on Turkish market, the owners of the concern had to publish the full recipe for the drink, inincluding the famous secret ingredient. Themturned out to be a food additive carminic acid, produced fromcochineal. If you not yet in course, several species of insects of different families of the coccid suborder are called cochineal. Theirfemales are used to produce carmine, in other words, red dye. Previously, carmine was widely used intextile industry, and then he fell in love with the food industry - withit is used to color dairy products and sweets, which the consumer is ready to perceive only inred-pink colors.

The Coca-Cola concern, which absolutely legally sells around the world a weak solution of the drug cocaine under the name "Coca-Cola", was sued in connection with the presence in Coca-Cola of a substance that causes blood cancer - leukemia. This substance is called benzene. In this perverted Western society of drug addicts, you can’t just sue a concern for selling a weak solution of cocaine - you have to sue for the presence of benzene, but for the presence of cocaine in a drink for children, you see, you can’t !!! Any chemist knows the recipe for Coca-Cola simply from general considerations. Firstly, they themselves say that the recipe is made from the Kola plant, from which the drug cocaine is made. That is, Coca and Pepsi Cola - this is fundamentally - a weak solution of the drug Cocaine !!!

Indian NGO Center for Science and Environment (CSE ) published the results of its research, according to which in drinks bottled Coca-Cola in India, the level of pesticides is 30 times higher than the norms adopted in the EU, and in the Indian Pepsi - 36 times. According to the report CSE , in drinks produced by companies Pepsi and Coca-Cola in India, toxic substances such as DDT, lindane and chlorpyrifos were discovered. According to journalists BBC (after conducting its own investigation), produced as a by-product in one of the Indian factories Coca-Cola the fertilizer, which is then sold to local farmers, contains a powerful carcinogen, cadmium.

The active ingredient in Coca-Cola is phosphoric acid. Its pH is 2.8. For the transport of concentrate Coca-Cola the truck must be equipped with special containers designed for highly corrosive materials.

1. Aquacarbonated- sparkling water

The presence of carbon dioxide in water stimulates gastric secretion, increases the acidity of gastric juice and provokes flatulence - profuse gas. In addition, not spring water is used, but tap water, passed through special filters.

2 . E952 ( CyclamicacidandNa, K, Casalts, Cyclamic acid and its sodium, potassium and calcium salts).

Sugar substitute. Cyclamate - petroleum-based synthetic substance, 200 times sweeter than sugar, carcinogen, causes cancer used as an artificial sweetener. It has been banned from use in human food because it is a carcinogen that causes cancer. In 1969, by order of the Federal Food and Drug Administration ( FDA ) is prohibited for use in the United States, t.to. like saccharin and aspartame, it has been shown to cause bladder cancer in rats. Banned in Canada the same year. Banned in Japan, South Korea and Singapore in 1975. And in Indonesia, which supplies cyclamate to Russia, it is also banned. However, in Russia, 70% of all sweeteners are cyclamate, modestly referred to as part of carbonated water - K-952. It is imported into the country at 1,000 tons per year, because it is very cheap and has no limited shelf life (after all, 300 years cannot be considered a temporary limitation). During World War II, cyclamate, among other cheap products, was supplied to concentration camps.

3. E150d (Caramel IV - Ammonia-sulphite process, dye)

– sugar color 4 obtained by “ammonia-sulfite” technology ( CARAMEL 4 – Ammonia - sulphite ). That is, sugar color (burnt sugar) is obtained by processing sugar at certain temperatures with or without the addition of chemical reagents. In this case, ammonium sulfate is added.

4. E950 ( AcesulfamePotassium, acesulfame potassium)

200 times sweeter than sucrose. A mixture of acesulfame potassium and aspartame is widely used in soft drinks. Contains methyl ester, which impairs the functioning of the cardiovascular system, and aspartic acid, which has a stimulating effect on the nervous system and can, over time, become addictive. Acesulfame is poorly soluble.

5. E951 ( Aspartame)

Sweetener. Chemically unstable: when the temperature rises, it decomposes into methanol and phenylalanine. Methanol (methyl alcohol) is very dangerous: 5-10 ml can lead to death of the optic nerve and irreversible blindness, 30 ml can lead to death. In warm soda and aspartame is transformed into formaldehyde, which is the strongest carcinogen. Aspartame (aka: sweetly, slastilin, sukrazid, nutrisvit) provokes headaches, fatigue, palpitations, depression. Cancer does not cause, but brain tumor and tuberculosis in some cases provokes.

National Soft Drink Association ( NSDA ), representing 95% of the soft drink companies in the US, constituted a protest published in the Congressional Report on May 7, 1985, describing the chemical instability of aspartame. After weeks in a hot climate (or being heated to 30 degrees Celsius (86 Fahrenheit), the main amount of aspartame in sparkling water decomposes into formaldehyde, methanol, phenylalanine, etc. Swallowed, methanol (the methyl or wood alcohol that killed or blinded thousands of drinkers) is converted to formaldehyde, then to formic acid (ant sting poison).

6. E338 ( Orthophosphoricacid, phosphoric acid) - chemical formula: H3 PO4 .

There is no person in this world who has never heard of the iconic drink called Coca-Cola. Everyone tried it, regardless of nationality, religion, place of residence and social status. For residents of Western countries, eight letters on a red background of the label are almost sacred at all. But where did the triumph begin?

History of creation

Coca-Cola was invented in the USA in 1886. It's not weird at all. Another thing is strange: the first to prepare this wonderful drink was ... a pharmacist. The first version of the cult soda consisted of coca leaves (yes, yes, the same coca from which cocaine is still made today) and nuts from the cola tree. The composition was patented as ... a remedy for upset nerves. Coca extract was removed from the drink much later, and its popularity came even later.

Pepsi was also invented by an American pharmacist. His name was Caleb Bradham. This was in 1898. Unlike Coke for nerves, Pepsi did not contain drugs, but the digestive enzyme pepsin. By the name of this very enzyme, the drink began to be called. By the way, initially Pepsi was recommended to improve digestion.

How Coca-Cola became carbonated

One day, a customer suffering from a hangover came into the pharmacy. The man really wanted to buy a tonic - Coca-Cola, not yet a carbonated drink. It cost only 25 cents, and the symptoms of a hangover removed "like a hand." Having paid for the purchase, the unfortunate man asked the pharmacist to add some water to the product. The pharmacist did not want to go to the other end of the hall, where the tap was located, so he suggested diluting Coke with soda. The sufferer didn't care, he agreed without hesitation.

Having tried the “prototype” of carbonated Coca-Cola, the unlucky buyer exclaimed: it tastes much better than with plain water! The news instantly spread around the district - and everyone, without exception, wanted to try the new Coca-Cola. Thus began the era of carbonated Cola.

The unfortunate fate of the creator

The inventor of the first composition of Coca-Cola, John Pemberton, having organized a completely successful company, could not get out of poverty. Sales of the drink grew rapidly, but the company could not gain independence. Then it was decided to sell part of the enterprise.

In the process, the composition of the first version of the cult drink, or rather the tonic called Coca-Cola, was discovered to the world: lemon, lime and nutmeg oils, vanillin, extract nutmeg, caffeine, orange elixir, orange flower oil, and - of course - extract of the coca plant.

Pemberton went to better world On August 16, 1888, not so much poor, but practically poor. A stone tombstone appeared on his grave only 70 years later.

Triumph

Coca-Cola, being a little older than its carbonated competitor, has always been the world leader among drinks. Pepsi, in turn, has always acted as a catch-up. IN different time the gap between competitors has changed. Statistics show that in the 1950s, Coca-Cola was preferred by an average of five times more consumers than Pepsi. The next decade brought Pepsi much greater success: the gap between competitors has halved. Everything went back to normal in the 1980s.

Interestingly, people at the most different tests"blindly", as a rule, choose Pepsi.

Marketing

Pepsi's main marketing strategy is aggressive. Pepsi's commercial has been starred by so many stars that it could give shape to any company in the world. Also fickle Pepsi in terms of logos and slogans.

Coca-Cola, on the other hand, is different long-term marketing stability. Pepsi is banking on a younger, driven, aggressive consumer (the notorious NEXT generation). Coca-Cola, on the contrary, focuses on adults, family people, time-tested classics and stability.

Taste qualities

The question of the difference in tastes is very difficult, because it is strictly individual. A fairly large number of people do not distinguish between the taste of Pepsi and Coca-Cola. Those who discriminate say that the first is a little sweeter, and the second large quantity bubbles.

Another opinion taken from the Internet: Coca-Cola has dominant fruity notes, while Pepsi has rich taste cola. However, one should not forget that taste qualities drink often depend on the region where it was produced and bottled. And the sensations of taste are from the person who tastes this drink. Also may vary depending on the geographical location and the composition of both drinks.

Compound

This question cannot be considered very deeply for several reasons. It is known that the compositions of the considered drinks are almost identical. Coca-Cola has never revealed the full formula of the drink. The composition of Pepsi, on the contrary, is now known to the last ingredient. Why did it happen? Because in 1923, the company had to go through bankruptcy proceedings - and in the process, divulge all the information.

So what's the difference?

There is no doubt that the first compositions of Pepsi and Cola were different. Yes, and then pharmaceutical preparations were produced for different purposes. Having become world-famous drinks and eternal competitors in the struggle for the first place, Cola and Pepsi turned into "dark horses" - because their current composition is not fully known to the masses.

Drinks are united not only by the pharmacy past, but also by marketing innovations: many marketing moves, first used to promote Pepsi and Coca-Cola, are now included in marketing and advertising textbooks.

The public has always reacted violently to the popularity of these tasty but not-too-healthy fizzy drinks, linked by an eternal war for dominance, but people all over the world do not get tired of indulging themselves in a can or two of soda a day. And this is how empires hold on ...
