Introduction.

Tell me which of the guys

    Learn about the history of chocolate.

    Learn about the classification of chocolate, the criteria for quality chocolate.

    Study the beneficial and negative properties of chocolate.

    Conduct a survey of 2nd grade students.

Hypothesis: We believe that chocolate has a beneficial effect on human health and well-being.

Object of study: chocolate.

Subject of study: information about chocolate.

Research methods: analysis, generalizations, questioning.

From the history of chocolate.

In Africa, on the Gold Coast, under the shade of huge coconut palms, small, plump, sturdy trees hide from the scorching tropical sun. On their elastic, strong branches hang fruits in bunches that look like bright yellow cucumbers. Parrots and monkeys love to feast on them. If you remove the delicate, fancy fruit and cut it open, you will see rows of yellowish seeds. Each seed is the size of a large bean. These are cocoa beans.

In the tropics, these trees grow almost everywhere.And although the birthplace of cocoa is Mexico, the largest theobroma cocoa plantations are in Africa.

Do you know how the name “theobroma” is translated? - "Food of the gods".And this tree itself was revered as divine by ancient Indian tribes.Aztecs For example, they worshiped the chocolate tree. They made a wonderful drink from its seeds that restored a person’s strength.Moreover, it was incredibly sweet and aromatic, a truly divine drink!

Europeans were unaware of chocolate until the 16th century, when the Spanish conqueror Cortes brought it to the Spanish king from the distant shores of South America.Gifts for Charles 1 include cocoa beans. The king listened with curiosity and surprise to Cortez's story about the amazing drink.And soon in the royal palace, and then in the houses of Spain, an exquisite chocolate drink began to be served.

For the first time, Europe learned what a passion for chocolate is.At first, the beans were used only to prepare a drink - hot chocolate, which, by the way, was prepared without sugar and had a classically bitter taste. It was not considered a dessert dish and was a delicacy that only wealthy aristocrats could afford. A few centuries later, they thought of adding sugar to the drink - and it acquired a more familiar taste.Even later, milk and other nutritional additives began to be added to hot chocolate, and then confectioners began to create recipes for sweets, cakes and pastries containing chocolate.

WITH Since the sixteenth century, chocolate has been marching victoriously around the world, gaining more and more fans.

Classification of chocolate.

There are many types of chocolate:

Dairy This is the chocolate that necessarily contains whole milk powder and in which the cocoa mass content is 35-40%. In addition, it must contain vanilla, or vanillin flavoring.… . Porous chocolate is obtained mainly from chocolate mass, which is poured into molds to 3/4 volume, placed in vacuum boilers and kept in a liquid state (at a temperature of 40 C) for 4 hours. When the vacuum is removed, due to the expansion of air bubbles, a finely porous tile structure is formed (Wispa, Air).

Chocolate without additives made from cocoa mass, powdered sugar and cocoa butter. This chocolate has specific properties inherent in cocoa beans. By changing the ratio between powdered sugar and cocoa mass, you can change the taste characteristics of the resulting chocolate - from bitter to sweet. The more cocoa mass in chocolate, the more bitter the taste. (Golden Label, Luxury, Russian, Thumbelina).

Chocolate with filling prepared from chocolate mass without additives and with the addition of milk. It is produced in the form of bars, bars and other shapes with various fillings: nuts, fondant, chocolate, fruit jelly, cream, milk, cream.

Diabetic chocolate intended for patients with diabetes. Instead of sugar, chocolate contains sorbitol, xylitol, and mannitol.

Chocolate white prepared according to a special recipe from cocoa butter, sugar, milk powder, vanillin without adding cocoa mass, so it has a cream color (white).

Criteria for quality chocolate.

Real high-quality chocolate must meet the following criteria:

Have a uniform, smooth shiny surface; a whitish coating is unacceptable

The surface of the broken chocolate bar should be matte

When broken, high-quality chocolate emits a dry, characteristic crunch and does not stretch in any way.

Cocoa butter melts at 32 degrees, so real chocolate melts in your mouth

- “greasy aftertaste” - evidence of the presence of cocoa butter equivalents or substitutes in chocolate, which affects the quality.

We tested 6 types of chocolate:

All tested chocolate meets these requirements.

The benefits of chocolate and the negative effects of chocolate.

The debate between scientists about the dangers and benefits of chocolate continues to this day. Supporters and opponents of chocolate have strong arguments.Opinions differ about the health effects of chocolate. Here's the scientific opinion on the most common chocolate questions.

When consumed in moderation, chocolate can be a very tasty treat. Only one third of a chocolate bar per day is considered a healthy portion. Everything else is just pampering. What are the benefits of chocolate?

So there are many different reasons for and against using

chocolate. To eat or not to eat, and how much to eat – you decide for yourself. The main thing is that this product brings true pleasure to those with a sweet tooth.

Chocolate Guinness records.

Chocolate bar:

According to the Guinness Book of Records, the world's largest chocolate bar weighed approximately 2,280 kg. One of the confectionery companies fromI prepared this shocking specimen for the Eurochocolate exhibition held in Turin in 2000.

Tall chocolate bar:

In February 1991, the tallest chocolate model was created in Barcelona. The exemplary creature towered 8.5 m in height and delighted onlookers until they began to bite into the exhibit.

Chocolate heart:

A chef from Germany and his team created for the DayValentine's Day, the world's largest heart made of chocolate and gingerbread dough.The heart weighs about 922 kilograms, height and width are 5 meters.

The largest chocolate bar in Russia:

In Moscow, on the day of the “500 Years of Chocolate” holiday, the Volshebnitsa Confectionery Factory presented to all guests of the holiday the largest real chocolate bar in the world. This piece of confectionery art weighed 500 kg, its length was 2m 73 cm, width 1m 25 cm, and height - 14 cm. The chocolate was packed in real foil and a paper label.

Sweetie:

American confectioners have built a giant candy - a dark chocolate truffle more than 2 meters high and weighing 3 tons. Its height is more than two meters, and its diameter is approximately the same. It would fit almost 700 thousand regular-sized candies.

Conclusion.

Our assumption that chocolate does more good than harm has been confirmed. But you should eat chocolate in moderation. This has a beneficial effect on a person's mood. And if you have a test tomorrow.

Eat a piece of chocolate so that you have enough intelligence and strength to work.

Thank you for your attention!

  1. Introduction

Chocolate and chocolate candies are the most favorite treat among children and adults. Everyone knows that chocolate is delicious, but few people know whether chocolate is good or bad for the health of children and adolescents. Someone says that you should eat chocolate in moderation, because... it is harmful to health: you can gain weight, your blood pressure can jump, you can develop dental caries, and much more. Some people, on the contrary, claim that chocolate makes you feel good, increases vitality, and gives strength and energy. So who is right?

We chose this topic for our research work because we want to answer this question.

We set ourselves the following target: Find out whether chocolate is good or bad for children's health.

In the process of work we will try to solve the following tasks:

  1. get acquainted with the history of the origin of chocolate;
  2. describe the main ingredients of chocolate;

3) analyze the composition of the most favorite types of chocolate by children;

4) conduct a questionnaire, survey;

5) find out what effect chocolate can have on children’s health.

Hypothesis: We assume that if chocolate is consumed in moderation, it has a positive effect on the human body.

Thus, our research will be useful for both children and their parents: everyone who loves chocolate and is concerned about their health.

Chapter I.

1.1. History of chocolate

In Africa, on the Gold Coast, under the shade of huge coconut palms, small, plump, sturdy trees hide from the scorching tropical sun. On their elastic, strong branches hang fruits in bunches that look like bright yellow cucumbers. Parrots and monkeys love to feast on them. If you remove the delicate, fancy fruit and cut it open, you will see rows of yellowish seeds. Each seed is the size of a large bean. These are cocoa beans. In the tropics, these trees grow almost everywhere. And although the birthplace of cocoa is Mexico, the largest plantations of theobora cocoa are in Africa.

The first cocoa beans appeared in Europe thanks to Christopher Columbus.
In the 17th century, scientists first discovered the medicinal properties of chocolate, which further increased its popularity. Chocolate was recommended

As a cure for many diseases, it was considered a means of promoting longevity.

In the 18th century, the first confectionery shops opened in France, where visitors were treated to a chocolate drink. And in England, such establishments were so popular that they eclipsed tea and coffee houses.

At the beginning of the 20th century, chocolate became widely available.

1.3. What kind of chocolate is there?

Regular chocolate:

Dessert chocolate:

Porous chocolate:

White chocolate:

Milk chocolate:

Black chocolate.

Chocolate with large additions:

It should be noted that almost all manufacturers of chocolate products are struggling to reduce the size of particles in chocolate, and the share of so-called “ordinary chocolate” is decreasing every year.

Very often, large additives are included in chocolate: nuts, almonds, raisins, etc.They not only add a special taste to chocolate, but also serve as good vitamin supplements.

Peanut not only very tasty and nutritious, but also has many benefits for diseases of the cardiovascular system. It contains vitamins with beneficial properties.

Hazelnut characterized by a high content of fat (60%), protein (20%), vitamin ‘E’, minerals: potassium, iron, cobalt.

Almond extremely rich in all components necessary for nutrition, indispensable for maintaining healthy teeth, hair and skin

Raisin It is useful to include it in the diet for diseases of the cardiovascular system, and raisins are also very useful for children and people with poor health, because helps improve immunity.

  1. Chocolate and children's health


Chocolate has many beneficial properties for the human body.

First, it contains caffeine, which, as you know,increases performance and creativity.

The most pleasant beneficial property of chocolate is“erasing” melancholy, stress and depression.

Chocolate lifts your mood, it is also called a recipe for happiness, it causes a surge of strength and energy.

Chocolate and tooth decay.Another problem that chocolate is blamed for is tooth decay. Let us take comfort: your favorite sweet contributes to the development of caries no more than other foods.

Chocolate and excess weight.Regarding excess weight from eating chocolate, let's say briefly: excess - from excess. Any product is harmful in large quantities.

Chocolate and heart.Chocolate - or rather, the cocoa products that make it up - contain substances that protect the walls of blood vessels, and therefore are beneficial for the heart and the entire circulatory system.

A series of experiments allowed scientists to conclude that moderate consumption of chocolate can extend a person’s life by a year.
Chocolate is useful for children, as well as for those who are actively involved in sports and mental work.
And the last argument in favor of chocolate: everyone really loves it! Maybe this is a sign of its usefulness? After all, if something tasty gives pleasure, it means that the body needs it, and it is no coincidence that our taste buds are so receptive to chocolate... So “Freedom for chocolate!”

2.4. Research results

2.4.1. Questionnaire and survey results

According to the results of the survey (Appendix 2), it was revealed that almost everyone (97%) consumes chocolate (except for 1 person surveyed). Greater preference is given to milk chocolate (55%), then white porous chocolate (40%), and only 2 people (5%) like bitter chocolate. The majority of respondents enjoy eating chocolate (75%), but there are also those for whom chocolate does not give the desired pleasure (25%). To the question: is chocolate healthy? – 57% answered “yes”, 43% answered “no”. When asked whether chocolate relieves depression, 70% answered “yes” and 30% “no”. 77% of respondents consider chocolate harmful, and 23% do not see any harm in it. 75% of respondents believe that chocolate spoils teeth, and 25% do not believe this. To the last question - “Are you interested in learning more about the origin of chocolate, the benefits and harms of chocolate?” - only 15% (6 people) did not want to.

Thus, the survey showed that most people do not know exactly what the benefits or harms of chocolate are, possibly due to lack of information.

Conclusions:

  1. prefer milk chocolate;
  2. they see benefits and harm in chocolate;
  3. They believe that it is harmful to the figure and teeth, but is useful because it lifts the mood and improves brain function.

Conclusion

If it's not harmful, does it mean it's useful? Scientists believe that chocolate, when consumed wisely, has a beneficial effect on the human body. And one more thing: one chocolate bar is superior in calcium, protein and other substances to a serving of fruit and vegetable salad made from carrots, apples, oranges, and bananas. So either a salad or a chocolate bar - rely on your taste.

What conclusions have we reached?

  1. the history of the origin of chocolate goes back more than 3000 years;
  2. chocolate necessarily includes proteins, fats, carbohydrates, as well as various additives (nuts, raisins, food additives - additives E 476 and E 322 are not classified as harmful food additives). It is advisable to buy chocolate that contains as few food additives as possible. The most suitable chocolates for children are “Bliss” and “Nesquik”, because... they contain a lot of proteins, carbohydrates and little fat;
  3. Everyone loves chocolate, they prefer milk chocolate most of all, most often they consume chocolate in a good mood;
  4. chocolate has a positive effect on the well-being of children, on their health: - chocolate contains an antiseptic substance that suppresses the action of bacteria that form tartar - caries;

Chocolate contains substances that protect the walls of blood vessels, which means they are beneficial for the heart and the entire circulatory system;

Dark chocolate helps you lose weight.

I would like to finally say: dear parents! If you want your children to be healthy, if you want to see your children happy, energetic and healthy - buy them chocolate more often! Better bitter! Don’t forget to take it yourself daily, and then we, your children, will also be happy that you are healthy and energetic!

FREEDOM FOR CHOCOLATE!!!

Conclusion: As a result of comparing the arguments of supporters and opponents of chocolate, we came to the conclusion that there are simply no serious reasons to deny yourself the consumption of real chocolate. You just need to remember that moderation is needed in everything.

Studying public opinion on the benefits and harms of chocolate The survey involved: 3rd grade students - 20 parents - 22 family members - 10 people A total of 52 people were surveyed.

CONCLUSIONS: 1. They prefer milk chocolate. They see both benefits and harm in chocolate. They believe that it is harmful to the figure and teeth, but is useful because it lifts the mood and improves brain function.

Thus, we can conclude that chocolate is a favorite delicacy of children and adults, but they know little information about it; everyone would like to know about the benefits and harms of chocolate, how and where it came to us.
