The origin, production process and pharmacological effects of Tieguanyin?

The origin of Tieguanyin is Anxi, Fujian; The production of Anxi Tieguanyin combines the characteristics of black tea fermentation and green tea non-fermentation, which belongs to the semi-fermented variety, and the fresh leaves collected strive to be complete, and then carried out cooling, sunning and shaking green.

Shaking green is an important process of making Tieguanyin, through the rotation of the cage, the blades collide with each other, and the edge of the leaves forms abrasions, which activates the decomposition of enzymes inside the buds and leaves, producing a unique aroma. In this way, turn and stop, stop and stop, until the tea fragrance is naturally released, when the aroma is strong, the brake green, kneading and wrapping are carried out, and the tea is rolled into granules and then simmered and dried, and finally it has to be sieved and sorted to make tea.

1. Tea cyanine: The collection of tea cyanine is based on the heart of the tea bud elongation leaf surface, and then takes its one heart and two leaves, commonly known as "open surface picking". The collection of tea cyanine occupies a very important prerequisite in the whole tea making process, when collecting tea cyanine can not be picked in rainy days and cloudy days, otherwise it will be difficult to make a mellow taste and aroma, Zhengtie Guanyin tea can only be collected from 9 o'clock in the morning to 4 o'clock in the afternoon.

2. Sunlight withering: Sunlight withering is also referred to as "retreat", which is to scatter the collected tea cyanine in the sun, so that the water content of the tea itself is divergent, and the sun is not too big.

3. Static and stirring: After the tea leaves are finished by sunlight, they must be moved to the house to stand, and turned and stirred at intervals, so that the water can continue to diffuse, so that the tea contains high fragrance components that are easy to volatilize.

Fourth, Langjing: Langjing is the use of Langjing machine to destroy the leaf veins of tea, so that the water in the tea is not lost, and a large number of various substances in the tea are released to the surface, and then the tea cyanine is pushed up to form a warm state more suitable for fermentation.

Fifth, kill the cyanine: kill the cyanine is to destroy the enzyme effect in the tea with high temperature, use the [frying machine] to fry the flavor of the tea cyanine until it subsides, the tea fragrance emerges, and the tea needs to be fried until the tea cyanine is vigorously rubbed by hand until the water is no longer out of the water.

6. Kneading and kneading: Wrap the tea in the cloth bag after the tea is chauffed, untie the cloth bag after squeezing and kneading it by machinery and hand, and then stir-fry, and repeat it 25 times before it is completed.

7. Final procedure: Dry and bake raw and cooked tea according to preference.

Hello dear, precautions for drinking Tieguanyin's fine sound: 1. Don't brew too strong when brewing Tieguanyin, Tieguanyin can also prevent the three highs, but it is not advisable to drink strong tea often, otherwise it will increase the burden on the stomach and intestines, increase the secretion of gastric acid and intestinal juice, and cause gastrointestinal discomfort. And drinking strong tea regularly can also make the heart hyperactive, which is not good for the heart.

2. It is not advisable to drink Tieguanyin before going to bed, Tieguanyin is rich in caffeine, and drinking it before going to bed will make you mentally excited and easy to make people insomnia. All teas made by a few suspicious people should not be drunk before going to bed, and Tieguanyin is no different.

Tieguanyin's refreshing and contemplative effect.

Drinking tea is known to almost everyone for its refreshing thoughts. There are many records of medical books in our country, and the literati and scholars and monks of the past dynasties have all waved their wonderful pens to praise the power of tea to refresh the mind and benefit the mind. Bai Juyi's poem "Gift to the East Neighbor King Thirteen" said:

Hand in hand with the poolside moon, open the bamboo wind. Dispel sorrow and know the power of wine, and see tea power when you break sleep. The poem clearly mentions the power of tea to refresh and break sleep.

Su Dongpo's poem said: "Thirty pieces of tea are built, regardless of how the taste is, they are presented to Bao laymen, and the monk's room fights the sleeping demon." He said that he gave Jiancha to Bao Jushi, so that he could drink it so that he could avoid dozing off when he was in meditation.

Drinking tea is loved by people, especially writers, poets and other mental workers. For example, the great French writer Balzac, the Chinese-American female writer Han Suyin, and the famous Chinese writer Yao Xueyin all love to drink tea to help literary thinking.

Tieguanyin can refresh the mind and think, and its function is mainly in the caffeine in the tea. Caffeine has the functions of stimulating the central nervous system, enhancing thinking, and improving efficiency. Therefore, after drinking tea, it can break sleep, refresh the mind, remove annoyance, relieve tiredness, clear the mind, enhance thinking, and can significantly improve the oral defense ability and mathematical thinking response.

At the same time, because Tieguanyin contains polyphenols and other compounds, it offsets the adverse effects of pure caffeine on the human body. This is also one of the important reasons why tea drinking has a long history, long-lasting prosperity and continuous development.

10. Tieguanyin's decanting and anti-smoking effect.

It is also a well-known fact that tea can decant wine and smoke. The famous sentence of "just like after being drunk, but you need tea to sober up" shows that the Chinese people have long recognized the effect of drinking tea to relieve hangover. The ancients often "poured their sorrows with wine" and "sobered up with tea".

Liu Yuxi, a poet of the Tang Dynasty, was drunk one day and remembered that Bai Juyi had "six classes of tea" to relieve hangover, so he sent someone to exchange for tea and sober up, which was passed down as a tea story by later generations. The composition of liquor is mainly alcohol, and a glass of wine contains 10% 70% alcohol. The polyphenols of Tieguanyin tea can cancel each other out with ethanol (the main ingredient in wine), so drinking tea can relieve hangover.

Tieguanyin can not only sober up wine, but also fight smoke. Because Tieguanyin contains a phenolic acid, it can precipitate nicotine in tobacco and excrete it from the body. At the same time, the caffeine in Tieguanyin can improve the liver's ability to metabolize drugs, promote blood circulation, excrete nicotine in human blood from urine, and reduce and eliminate the risk of nicotine.

Of course, this effect is not just a single effect of caffeine, but the result of synergistic cooperation with various ingredients such as tea polyphenols and vitamin C.

1. The anti-aging effect of TieguanyinSome scientific studies at home and abroad have shown that human aging is related to the excessive oxidation of unsaturated fatty acids in the body, and the excessive oxidation of unsaturated fatty acids is related to the action of free radicals. Free radicals with high chemical activity can cause excessive oxidation of unsaturated fatty acids, mutate or decline cell function, cause tissue proliferation and necrosis, and produce deadly diseases. Lipid overoxidation is the devil of human health, but the culprit is free radicals, as long as the free radicals are removed, the cells can achieve normal growth and development and live a long and healthy life.

In general, commonly used antioxidants are vitamin C and vitamin E, which are effective in preventing excessive oxidation of unsaturated fatty acids. Recently, Japanese researchers have shown that the polyphenolic compounds in Tieguanyin can prevent excessive oxidation; Purine alkaloids can indirectly play a role in scavenging free radicals, thereby achieving the purpose of delaying aging.

2. The anti-cancer effect of TieguanyinCancer is an "incurable disease" that seriously threatens people's health today. Therefore, in recent years, the study of tea anti-cancer has attracted great interest and attention. A few years ago, there was a report that the fact that Shanghai citizens drank tea to reduce esophageal cancer year by year, so drinking tea can prevent the occurrence of cancer caused great repercussions around the world.

Nowadays, drinking tea can prevent cancer and anti-cancer has been recognized by the world, and the best anti-cancer effect in tea is Tieguanyin. As early as 1983, Professor Takuo Okuda of Okayama University in Japan screened dozens of plant polyphenolic compounds for anti-carcinogenesis effects, and the results proved that catechins (EGCG) have strong anti-carcinogenesis activity.

Other scientists have confirmed the anti-mutation of Tieguanyin in their studies, and believe that Tieguanyin tea polyphenols are the main active ingredients of this effect; In the study of carcinogenesis caused by chemical substances, the anti-carcinogenesis effect of Tieguanyin tea polyphenols was affirmed. In addition, vitamin C and vitamin E in Tieguanyin can block the synthesis of carcinogens - nitrosamines, which have a greater effect on the prevention and treatment of cancer.

Generally speaking, the Tieguanyin tea we buy is basically 7 grams per pack of packaging, this packaging method uses vacuum compression packaging method, if it is such a package, and with the outer can packaging, if you will drink it in the near future (within 20 days), generally only need to be placed in a cool place, away from light preservation, if you want to achieve the best effect of preservation and the longest time limit, it is recommended to keep it fresh at minus 5 degrees in the quick-freezer, so as to achieve the best effect. However, Tieguanyin tea as a drink, even if it has been dried and compressed packaging, it does not mean that it can be stored permanently, if you want to drink a fresh taste, it is recommended to buy home Tieguanyin tea is best to keep it fresh in the freezer box at minus 5 degrees, not more than one year at most, it is better to drink it within half a year! For the preservation of Tieguanyin, low temperature and sealed vacuum are generally required, so that the color and fragrance of Tieguanyin can be guaranteed in a short period of time, but in the actual preservation, why there are often tea leaves that are not stored for a long time but the color and fragrance are not as good as the tea that began to brew, the reasons are as follows:

The degree of drying after tea fermentation The tea making technology currently used changes in the direction of light fermentation, which is a typical representative of the tea in the middle, in light fermentation, the tea is easy to reflect the high orchid fragrance, and the tea soup is also more beautiful (presenting the standard mung bean soup), but to let the dry tea reflect the aroma, the tea will not be too dry in general, and the tea contains a certain amount of moisture, so that the tea must pay attention to the low temperature and sealing of the tea when it is stored in the later stage, so as to reduce the role of moisture in the tea. If the tea leaves are relatively dry and feel crisp and dry in the hand, such tea has lower requirements for low temperature. The control of the degree of tea fermentation Experienced tea makers in the control of tea fermentation is to fully consider the problem of market circulation and preservation, so in the tea making will be through the control of the degree of fermentation to maintain the fresh fragrance of tea, generally speaking, we all know the curve of the crest and trough, so if the fermentation is close to the peak when the tea is controlled, then the tea is made after the passage of time after the post-fermentation, so that the tea can be preserved for a long time, if the tea has begun to ferment to the peak, In the process of preservation, it is necessary to pay attention to the formation conditions of inhibiting the post-fermentation of tea - that is, to control the contact between temperature and air.

It is well known that there are many benefits of drinking tea. But why do drinking tea have so many benefits? For the average person, Tieguanyin - the bottom of the leaves.

I know it, but I don't know why. With the development of science, it was not until the beginning of the 19th century that the composition of tea was gradually clarified. After modern scientific separation and identification, tea contains more than 450 kinds of organic chemical components and more than 40 kinds of inorganic mineral elements.

The organic chemical components and inorganic mineral elements in tea contain many nutrients and medicinal components. Organic chemical components mainly include: tea polyphenols, plant alkalis, proteins, amino acids, vitamins, pectins, organic acids, lipopolysaccharides, sugars, enzymes, pigments, etc.

The organic chemical components contained in Tieguanyin, such as tea polyphenols, catechins, and a variety of amino acids, are significantly higher than those of other teas. Inorganic mineral elements mainly include: potassium, calcium, magnesium, cobalt, iron, manganese, aluminum, sodium, zinc, copper, nitrogen, phosphorus, fluorine, iodine, selenium, etc.

The inorganic mineral elements contained in Tieguanyin, such as manganese, iron, fluorine, potassium, sodium, etc., are higher.

The article also analyzes the social attributes of Anxi Tieguanyin, and believes that Anxi Tieguanyin, as a high-quality tea, has a unique effect in hospitality, making friends and personal self-cultivation. The article said that Anxi Tieguanyin needs to be brewed, and when entertaining guests, it is necessary to boil water to wash the cup. The guests enjoy tea while catching up with the host, and the process is very harmonious and friendly, so the programmed brewing and drinking make people calm and conducive to nurturing and pleasant feelings.
