Catechin, also known as catechin essence, tea tannin, is a kind of phenolic active substance extracted from tea and other natural plants. Catechins have obvious phenolic properties and can precipitate heavy metals and proteins, so it is a phenolic substance. Accounts for about 75 to 80 percent of tea polyphenols and is one of the sources of tea's bitter taste. Phenolic substances are also known as tannins or tannins because they precipitate proteins and have the properties of tanning raw skins into leather of varying sizes.
Epicatechin can be divided into four types: ① Epicatechin (EC); ② Epigallocatechin (EGC); ③ Epicatechin gallate ECG; ④ Epigallocatechin gallate EGCG.
Clinical investigation shows that catechins can enter the whole body through blood circulation, strengthen metabolism, enhance fat oxidation and energy consumption, so as to achieve the inhibition of obesity, especially the inhibition of visceral fat, can achieve ideal weight loss effect. It is a reductive polyphenol, easily oxidized by air in aqueous solution, and is often used as an antioxidant. It can also be used in dyestuff and tanning industry.
One, scavenge free radicals: catechins are natural oil antioxidants with even higher antioxidant activity than vitamin E! And can remove free radicals produced by the body, to protect the role of cell membrane.
Second, catechin has the effect of delaying aging: because it has the function of removing free radicals, it can slow down aging.
Third, catechin has the effect of preventing tooth decay: because tea contains fluorine, it can make teeth have a strong resistance to acid erosion. In addition, clinical trials have shown that catechins can significantly reduce dental plaque and alleviate periodontal disease.
Four, catechins have the effect of changing the distribution of intestinal microbes: catechins can inhibit pathogenic bacteria in human body, while not harming the reproduction of beneficial bacteria, so it has the function of whole intestine.
Five, catechin has antibacterial effect: it can inhibit the germs that cause human skin diseases, and has a very good effect on the treatment of eczema.
Six, catechin has deodorant effect: catechin can remove the stench of methanethiol, so it can remove the bad breath of smokers, and reduce the stench of pig, chicken and human feces.
Other aspects of the efficacy and role of catechins: some other studies have shown that catechins can also inhibit blood pressure and blood sugar, reduce cholesterol and low density lipoprotein in blood, and increase the amount of high density lipoprotein, anti-radiation, uv, anti-mutation and other functions.
