Green tea is a type of tea that is made from Camellia sinensis leaves and buds that have not undergone the same withering and oxidation process which is used to make oolong teas and black teas. Green tea originated in China.
Green tea is a shrub or small tree plant of the family Theaceae Camellia. Green tea is natural in shape and bright green in color. It is made from new leaves or buds of tea trees, which are processed by killing, shaping, and drying, and retains the natural substances of fresh leaves; tea leaves Pointy and slender, smooth surface; white flowers, small, polygonal; flowering period from October to February of the following year. Green tea is named because its dry tea is green, the tea soup after brewing is green, and the bottom of the leaves is emerald green.
Green tea originates in China, and is widely distributed in China's Henan, Guizhou, Zhejiang and other places, and is also distributed in Japan, Thailand, North Korea, South Korea and other countries. Green tea likes a humid and warm environment, and is not tolerant to sunlight, high temperature, and humidity. Fertile and loose slightly acidic soil is suitable for planting. The propagation methods of green tea mainly include seed propagation and cutting propagation, and cutting propagation is generally adopted.
Green tea is non-fermented tea, because of its characteristics, it retains more natural substances in fresh leaves. Among them, tea polyphenols and caffeine retain more than 85% of fresh leaves, chlorophyll retains about 50%, and vitamin loss is less, thus forming the characteristics of green tea "clear soup and green leaves, strong astringent taste". It has special effects on anti-aging, anti-cancer, anti-cancer, sterilization, anti-inflammatory, etc., which is inferior to fermented teas.
Green tea extract is the active ingredient extracted from green tea leaves, mainly including tea polyphenols (catechins), caffeine, aromatic oils, water, minerals, pigments, carbohydrates, proteins, amino acids, vitamins, etc.
Tea polyphenols have the functions of anti-oxidation, scavenging free radicals, etc., significantly reducing the serum total cholesterol, triglyceride, and low-density lipoprotein cholesterol levels in hyperlipidemia, and at the same time have the effect of restoring and protecting vascular endothelial function. The hypolipidemic effect of tea polyphenols is also one of the main reasons why tea can make obese people lose weight without rebounding.
Main Function of Green Tea Extract:
【Antioxidant effect】: Tea polyphenols can block the process of lipid peroxidation, increase the activity of enzymes in the human body, and thus have the effect of anti-mutation and anti-cancer.
【Hypolipidemic effect】: Tea polyphenols can significantly reduce serum total cholesterol, triglyceride, and low-density lipoprotein cholesterol in hyperlipidemia, and at the same time restore and protect vascular endothelial function. The hypolipidemic effect of tea polyphenols is also one of the main reasons why tea can make obese people lose weight without rebounding.
【Tumor inhibition effect】: Tea polyphenols can inhibit the synthesis of tumor cell DNA and induce the breakage of mutant DNA, thus inhibiting the synthesis rate of tumor cells and further inhibiting the growth and proliferation of tumors.
【Sterilization and detoxification effect】: Tea polyphenols can kill botulism and spores, and inhibit the activity of bacterial exotoxins. It has an antibacterial effect on various pathogenic bacteria that cause diarrhea, respiratory tract and skin infections. Tea polyphenols have a significant inhibitory effect on Staphylococcus aureus and Proteus that cause purulent infection, burns, and trauma.
【Help hangover and liver protection】: Alcoholic liver damage is mainly free radical damage caused by ethanol. As a free radical scavenger, tea polyphenols can inhibit alcoholic liver damage.
【Detoxification effect】: Severe environmental pollution has obvious toxic effects on human health. Tea polyphenols have a strong adsorption effect on heavy metals, and can form complexes with heavy metals to produce precipitation, which is beneficial to reduce the toxicity of heavy metals to the human body. effect. In addition, tea polyphenols also have the effects of improving liver function and diuresis, so they have a good anti-reactive effect on alkaloid poisoning.
【Improve the body's immunity】: Tea polyphenols can increase the total amount of human immunoglobulin and maintain it at a high level, stimulate the change of antibody activity, thereby improving the overall immunity of the human body, and can promote the body's own conditioning function.
