2, refreshing

Caffeine has bitter taste and is an important component of tea soup. In black tea soup, it combines with polyphenols to form a complex; Emulsifying phenomenon will be formed when the tea soup is cold. Tea-specific catechins and their oxidative condensation products can slow down and maintain the excitement of decaffeination, so drinking tea can keep people awake and have more endurance.

Brief introduction of tea:

Tea (scientific name: Camellia sinensis (L.) o.ktze) o.ktze.), shrub or small tree, with hairless shoots. Leaves leathery, oblong or oval, blunt or sharp at the top, wedge-shaped at the base, shiny on the top, hairless or initially pilose on the bottom, serrated at the edge, and glabrous on the petiole. Flowers are white, and sometimes the stalks are slightly longer; Sepals broadly ovate to rounded, glabrous, persistent; Petals broadly ovate, slightly articulated at base, glabrous on back, sometimes pubescent; Ovary densely covered with white hairs; Style glabrous. Capsule 3 is spherical or 1-2, with a height of1.1-0/.5cm, and each ball has 1-2 seeds. The flowering period is from June 10 to February of the following year.

Wild species are all over the mountainous areas of the provinces south of the Yangtze River in China. They are small trees with big leaves, usually more than 10 cm long. For a long time, after a lot of cultivation, great changes have taken place in hair and leaf shape. Tea can be used as a beverage, which contains many beneficial ingredients and has health care function.

Beneficial ingredients:

1. Tea polyphenol is the most soluble component in tea, and it is also the most important substance for tea to play a health care role. The most typical representative is catechin (phenol), which has many functions, such as antioxidation (scavenging oxygen free radicals), anti-inflammation, reducing the incidence of cardiovascular diseases, preventing cancer, lowering blood fat, reducing body fat formation, resisting bacteria, changing the ecology of intestinal flora and so on. Studies show that after drinking a cup of tea for half an hour, the antioxidant capacity (the ability to resist oxygen free radicals) in the blood increases by 465,438+0% ~ 48%, and it can last for one and a half hours.

2. Tea pigments mainly include chlorophyll and β-carotene. It has the functions of detumescence, anti-aging and beauty.

3. Theanine can improve brain function and enhance memory and learning ability. Can be used for preventing Alzheimer's disease, Parkinson's disease and autonomic nervous dysfunction.

4. Tea polysaccharide is a complex mixture. Tea polysaccharide has the functions of anti-radiation, increasing the number of white blood cells, improving immunity and lowering blood sugar. The folk practice of drinking coarse tea to treat diabetes is mainly to play the role of tea polysaccharide.

5. The content of υ-aminobutyric acid in natural tea is not much, but it is greatly increased after processing. The main function of γ -aminobutyric acid is to dilate blood vessels and lower blood pressure, so it can be used as an auxiliary treatment for hypertension. It can also improve cerebral blood circulation, enhance the metabolic ability of brain cells, and contribute to the rehabilitation of stroke and cerebral arteriosclerosis sequelae.
