Theme: Are tea in tea bags harmful or useful for people?

The problem of the work is that many people think tea in tea bags are harmful for our health.

The actuality of our work is influence of packaged tea on the health of people

The aim of the work is to identify advantages and disadvantages of tea in tea bags

The tasks of the work:

1. To study the history of tea

2. To learn special features of tea

3. To identify advantages and disadvantages of tea bags

4. To establish benefits and harms of tea to the human body

The hypothesis is if we drink tea in tea bags every day, it will harm our health.

The methods:

1. Searching researches

2. Theoretic analysis and generalization of the information and the practical experience

3. Chemical method of experiments

4. Statistic method of material and processing of the research

The theoretical value is that we studied and compared advantages and disadvantages of the tea bags, studied tea-drinking traditions in Russia and Great Britain.

The practical value is that we investigated the composition and properties of tea bags, effect of product on the organism

Tea in Ancient China

There are many legends about the appearance of the first tea in China

The first legend tells us that the Emperor of ancient China Shannon boiled pot of water. Suddenly the leaves of the tea fell into the pot. When Shannon tasted, he was astonished that the drink was delicious.

The second legend says that in ancient time, the shepherds noticed that animals which were eating leaves of tea tree, became very cheerful. People also decided to try a decoction of these leaves. So they learned that the tea was incredibly tasty, healthy and well toned. Then the tea began its journey around the world. [2]

Another legend tells that in China lived a monk who decided to pray without ceasing, without rest and sleep. But a few days later the dream still overcame him, and the monk fell asleep. When the monk woke up, he decided to cut off the eyelids so that they could not be closed against his will. But when the eyelids touched the ground, they turned into the tea leaves. And since then, from it people make refreshing drink which saves from drowsiness.

The next legend tells about Emperor Yan Dee, who collected medicinal plants. One day he was betrayed and poisoned, while the Emperor remained nothing how to go and wait for death. He has hardly reached a tea tree lay down to die. But in a random way juice from leaves has got into Jan Dee`s mouth, and he has been wonderfully cured.

Tea ceremony in Great Britain

England wasn’t the pioneer of tea, tea came to England from China in. The British East India Trading Company presented tea as a gift to the King Charles II in 1664. That time tea was indeed a royal gift because its price was high. Drinking tea became a tradition only in 1840.The 7th Duchess of Bedford Anna ordered to serve tea with bread, butter, cakes and biscuits. Since the 17th century, its presence is felt everywhere: from the estates of the wealthy people to the huts of the poor people. Despite the fact that this drink was luxury and was available only to rich people, by the 20th century tea became one of the cheapest and the most refreshing drink. For the last more than 20 year tea became one of the simplest pleasures in life: from morning to evening tea takes away fatigue, quenches the thirst and allows us to relax. Through this wonderful drink there was a replacement of drinks with the tea which was becoming more and more popular and available. So, the average life expectancy has considerably increased in Britain. [6]

Traditionally British prefer to serve their tea in porcelain teapots and teacups. They drink Black tea (English breakfast and Earl Grey), White tea, Green tea and Herbal tea. English breakfast fills you with energy. You can relax with Earl Grey. Green tea is good after meals. English tea is a mixture of several black teas from India and Sri Lanka.

There are 2 types of tea time in England: Low tea (afternoon tea), High tea (meat tea). Low tea is served with light snacks such as finger sandwiches, crumpets, pies with ginger and scones. High tea includes meat, bread, dishes and dessert. Most British enjoy a cup of tea in the afternoon. They have jam, scones and cream. Many of them don’t put sugar in their tea. First they pour some milk into the cup and only then they pour some tea. They drink from China cups.

The British drink tea 6 times a day. Each time of the day has its own variety of tea and its tradition of tea drinking.

• "Early morning cup" - An early cup of tea before washing and dressing - because of the wet climate of England, famous for its morning fog. The British wake up early. They need a cup of strong tea to wake up.

• For breakfast English people have another cup of tea.

• Lunch. This tradition appeared during the reign of Queen Victoria as a small meal with a cup of tea.

• “5 o’clock tea”. Traditional snacks for tea - warmed sandwiches, toasts.

• Tea at 7-8p.m. is called “High Tea”

• A cup of tea – before sleeping.

Tea ceremony appeared at the request of the queen Anna in 1840. The queen decided to reduce an interval between lunch and supper with 5 o’clock tea drinking. All citizens of England aimed to imitate the queen, so the tradition of tea drinking at 5 o’clock they happily adopted.

The attributes of tea drinking are tea with milk, fresh and delicious buns, which were served on the beautiful silver tray. [7]

The traditional way of making English tea:

1. Boil some fresh water into the teapot

2. Put some hot water into the teapot to make it warm.

3. Pour the water away.

4. Put one tea spoon of tea-leaves per person, and one extra tea-spoon into the pot

5. Pour boiling water into the tea.

6. Leave for a few minutes

7. Serve with hot milk

Tea in Russia

Russia as Britain wasn’t the pioneer of tea. Probably Russian merchants and travelers to the East have learned about tea since the time of the Horde. The history of Russian tea has more than one hundred years. It began in 1638.A Russian Tsar Michael Fedorovich got a special gift from the ruler of Mongolia. It was 64 kg of tea. At first the king didn’t like it. They drank herbal tea. Import of tea to Russia began in 1769 when the contract with China was signed. For a long time tea was popular only in Moscow because of its high price.The way from Pekin to Moscow took more than a year. At the end of the 19th century tea became cheaper. In the 18th century only wealthy merchant families drank tea. In the 19th century tea was spread everywhere. Now it is impossible to imagine our life without tea.

In Russia tea was received through the Northern provinces of China, where local dialects it was called "cha" — hence the Russian word "tea". The British originally bought this product in the Maritime provinces of China, the dialects of which he was called "te" — hence the English "tea". [1]

There was an idea to arrange own production in Russia. For this purpose Russia bought tea bushes and created tea plantations near Kizlyar, in the most southern point of the Russian Empire. The first tea-bush in our country has been planted in the Nikitsky botanical garden in the Crimea after the end of Napoleonic wars, but until the end of the 19th century all attempts to grow up tea remained experimental.

Russian people drank tea from samovars. Samovars were made of bronze and copper. Samovar is a symbol of comfort, hospitality. It is a good invention that combines a kettle with heating chamber inside.

The High Russian society began to learn English tea traditions. To receive an invitation to the tea party was the opportunity to communicate, demonstrate the exquisite manners, and have a cup of tea and a little snack.

A lot of Russian people like to drink tea with herbs (Raspberry, thyme, Johns’ tea), lemon or with honey, jam, pies, cakes, cookies, sweets. In Russia tea is served after meals and during mid- afternoon breaks. [3]

The method of making tea in Russia is not different from the English way.

Until the 19th century the markets were sold only loose leaf tea, because there weren’t tea bags.

The idea to create tea bags came to Thomas Sullivan in 1904, when a ship carrying his tea was flooded. In the hold were stored the tea in bags. Thomas was upset, he thought that the product is spoiled. But customers bought wet product with great pleasure. Traditionally, the tea was sold in large cans, but Sullivan decided that it would be cheaper to use small packaging, but as dishes chose silk bags. He supposed that customers would pour the contents into a cup and will brew a tea, but the customers decided that tea bags should put into a cup and brew. So the tea bags appeared .

Advantages of this type of tea:

• Demanding one tea cup

• Convenient to make

Disadvantages:

• Expensive

• Less aromatic

• Not high quality

Practical part

Many people prefer leaf tea, because they think that tea bags are made from tea dust and haven’t got useful properties. Unfortunately it is the truth. But there are also conscientious producers, which don’t use tea dust at production of a product.

Thus, tea bags have got lower quality, but enjoy great popularity.

Does this product contain any harmful substances?

Let's get to the practical part of the work. It is that we experimentally investigate the composition and properties of packaged tea as well as the effect of the product on human health.

Firstly, define the contents of tannin. Tannin is natural dye which gives color, aroma, tartness to tea. For this purpose we need citric acid, a tea bag, a cup, boiling water. We put tea bags into a cup, fill a cup with boiling water (Appendix 1), then, add a little bit of citric acid. If tea contains a lot of tannin, it dyes. In this case the content of tannin is enough (Appendix 2). This natural dye strengthens blood vessels. Therefore, in the first experiment, we found that tea in tea bags doesn’t harm the health, and on the contrary have the tonic effect. Also, it is necessary to detect unnatural dyes. For this purpose the bag of tea should be placed in cold water. If the water is colored, the tea contains artificial coloring. The color of my solution didn’t change, so my sample hasn’t got unnatural dyes (Appendix 3). From this we can say that the tea does not contain harmful dyes, and thus hasn’t got harmful properties.

Except these 2 ways, to define the quality of tea is possible with indicator pH. Make tea from a tea bag (Appendix 4), then, put into the solution a stripe of indicator pH. Correlate the received color with the color picker of indicator pH. For example, when I put a stripe into whiteness, my stripe became dark green (Appendix 5). But when I put a stripe into tea, it became yellow (Appendix 6). So, tea has got mid acid condition that is harmful for out organism.

Two researches from three have shown positive results.

The inhabitants of our planet love tea. For its popularity it is second only to water.

The history of tea is very old, if you believe the myths, it is more than four thousand years. And during this time there were invented many varieties of tea bushes and invented countless ways of brewing the tea.

At such huge popularity of tea there are countries where it is loved and consume most of all. It is surprising, that in this list of champions there are no China, and India — main inventors and manufacturers of the best tea in the world. In India there is the low standard of living and tea is expensive so not everyone can afford it. In China there are traditional methods of a making tea which allow to spend tea very economically. Moreover, the Chinese prefer green teas that are not only possible but also need to brew many times, so the average figures of consumption of the tea leaves per capita are not so big.

Many believe that the UK drunk a lot of tea. Because here was born a famous custom - "Fife-o-clock tea". But it’s false. Tea is drunk, of course, not only at 5o’clock, but throughout the day. British very well understand grades of tea and with what additives it is better to combine.

The research showed that Turkey is the biggest consumer of tea in the world. There is everyone drinks on average 3.2 kilograms of tea a year. The second place was received by Ireland. Its result is 2.1 kilograms of tea a year. Then there is Great Britain, where each person drinks 2 kilograms of tea a year. The fourth place went to Russia, where everyone drinks on average 1.4 kilograms of tea a year. In Morocco and New Zealand each person drinks 1.2 kilograms of tea a year. Egypt, Japan, Saudi Arabia are completed the top ten, in this countries everyone drinks on average 1 kilogram of tea a year.

After studying tea I asked my classmates question.

The question: “What do you prefer packaged tea or loose leaf tea?”

65 percent of respondents prefer packaged tea to loose leaf tea. They argue their choice by the fact that packaged is easy to prepare and you shouldn’t wash teapot, you only need to throw away the tea bag.

After studying tea bags I have came to conclusion, that although packaged tea has significant disadvantages, one of the most important is low quality, but this kind of tea is very popular because of speed and convenient of preparation.

After researching among the classmates, I saw that a lot off students prefer packaged tea to loose leaf tea. They explain it with the fact that the packaged tea is convenient in preparation.

But my family is fancy brewing loose leaf tea. My mother presumes that tea bags are harmful for our organism and haven’t got rich aroma. I partially agree with her.

But actually the researches demonstrated that tea in tea bags doesn’t harm our health and has even got a tonic effect.

Eventually we have made the conclusion that our hypothesis wasn’t confirmed.
