Green tea can sterilize, and it is also the favorite of many female friends who want to lose weight. It tastes refreshing and can effectively relieve the summer heat. It also has other different functions. Let's have a look.

First, the brewing method of green tea

1. Pouring method: First, pour enough hot water into the teacup (tea bowl) at one time, and then pour the tea leaves when the water temperature is moderate. This method is mostly applicable to tender roasted green tea (such as Super Longjing, Super Biluochun, Super Xinyang Maojian, Luan Guapian, Lao Zhu Dafang, etc.). ) and tender roasted green tea (such as Zhuxi Feng Long, Tingxi Lan Xiang, Huangshan Mao Feng, Taiping Monkey Kui and Jingting Lv Xue). ). This method needs to master the water temperature very accurately. The more tender the tea leaves are, the lower the requirements for water temperature are. Some teas can wait until 70℃ before you put them in. Therefore, ordinary drinking water operation is difficult and inconvenient.

2. Investment method: After putting the tea leaves in place, first inject one third of hot water (especially the tea leaves just taken out of the refrigerator), and then inject hot water after the tea leaves have absorbed enough water and dispersed. This method is suitable for tender but loose or compact green tea (such as Yingshan Wu Yun, Zhuyeqing and Wuyuan Mingmei).

3. Drip method: put tea leaves first, and then fill the teacup (tea bowl) with hot water at one time. This method is suitable for ordinary green tea with poor tenderness.

4. Method of cooling before heating: After putting the tea leaves in, soak them in a small amount of drinkable cold water for about three minutes at room temperature, so that the tea leaves can absorb enough water and fully stretch, and then inject enough hot water at one time. At this time, the temperature of hot water can be slightly higher, 85-95℃. The water temperature in winter is 100℃. This method is suitable for brewing various grades of tender tea, but it should be mastered properly.

Second, what kind of green tea is best?

picking season

Spring tea is the best green tea, followed by winter tea. So it's better to buy it in spring, which is fresher. If you buy it in summer and autumn, not only the quantity is small, but also spring tea is usually too fresh when stored at this time.

Green tea is usually made by picking young buds. After roasting, the buds will form white hairs, called white hairs or silver hairs, which are better tea leaves.

Pay attention to the date of production

When buying packaged green tea, pay special attention to the production date and shelf life. In principle, the fresher the better. Once opened, drink it as soon as possible to avoid losing the fresh fragrance and nutrition of green tea.

Look at the color. Where the color is green, the tea is fat and thick, or there are more white hairs, it is generally spring tea.

Look at the appearance. Flat green tea is flat, straight and smooth, without yellow spots and green stems, and it is a good tea; Curled or spiral green tea, with thin cords and white hairs or sharp seedlings, shows good raw materials and fine workmanship.

Smell the fragrance three times. It is a good tea with fresh and rich aroma and a little ripe chestnut fragrance.

Third, the efficacy and role of green tea

Summer is usually the time when the solar radiation is maximum. At this time, you can choose all kinds of things with green tea factors to smear on your face. In this way, even if exposed to the sun, the skin will not be harmed by the sun, and at the same time, it can enhance the skin's ability to resist solar radiation.

Many people spend a long time facing the computer, especially some white-collar workers. Their time on the computer is often several times of their rest time, so in this case, everyone must reduce radiation. For example, you can drink more cups of green tea, reduce radiation, or drink more things containing vitamin A, which will improve your eyesight. Green tea is the favorite of many people in like's eyes.

Because the quality of real life has improved, every household has the ability to eat meat and vegetables. Of course, with the improvement of life, the frequency of human illness is also high. Therefore, at this time, everyone consumes too much cholesterol, so we must let the body reduce the intake of this substance, and at the same time effectively excrete too much fat. We might as well choose green tea, which can help digestion and reduce excessive fat intake.

Fourth, drinking green tea regularly can prevent Alzheimer's disease.

It is reported that the research team of Professor Masahito Yamada from the Department of Neurology, Kanazawa University conducted a questionnaire survey on the frequency of drinking green tea among 723 people over 60 who did not suffer from dementia five years ago. Among them, 490 elderly people were divided into three groups: no drinking at all, drinking 1-6 times a week and drinking every day for five years.

The results showed that among 138 people who did not drink alcohol at all, 43 people were diagnosed with mild cognitive impairment after 5 years, accounting for 3 1% of the whole group. Among the 195 people who "drink 1-6 times a week", 29 people were diagnosed with mild cognitive impairment, accounting for 15% of the whole group. Of the 157 people who drink green tea every day, 18 people were diagnosed with mild cognitive impairment, accounting for 1 1% of the whole group.

In addition, the research results also show that it may be because green tea contains more polyphenols such as catechin and myricetin, which has the function of preventing dementia. Professor Yamada said that "the research on the components contained in green tea will be linked with the prevention of dementia for further research".
