EGCG powder is Epigallocatechin gallate, which is extracted from Green tea leaves. EGCG is the main component of green tea polyphenols and the most effective active component. The catechin monomers isolated from tea leaves are the functional components with the highest activity and most content in catechins. And is the most active and most abundant functional ingredient in catechins. The general content is 30-50mg per gram of green tea. Because of its special stereochemical structure, EGCG has very strong antioxidant activity. The EGCG antioxidant is More than 100 times of vitamin C, and 25 times of Vitamin E, it can protect cells and DNA from damage.
The link between EGCG and tea polyphenols
Tea polyphenols are the main components of tea with health functions. Catechin is the main component of tea polyphenols. EGCG is the main component of catechins.
How much EGCG in green tea?
China's tea culture has a long history, and Chinese people are more particular about the types of tea. According to the degree of fermentation of tea, it can be divided into six categories: green tea (non-fermented), white tea (slightly fermented), yellow tea (lightly fermented), Oolong tea (semi-fermented), Dark tea (post-fermented), black tea ( fully fermented).
Among the six major types of tea, the content of tea polyphenols generally shows the following pattern: green tea>white tea>yellow tea>light-green tea>black tea>dark tea. The content of tea polyphenols in the six major tea types: green tea has a polyphenol content of about 330mg/g, white tea has a tea polyphenol content of about 290mg/g; yellow tea has a tea polyphenol content of about 250mg/g, and light-green tea has more tea polyphenols. The phenolic content is about 230mg/g, the tea polyphenol content of black tea is about 160mg/g, and the tea polyphenol content of black tea is about 100mg/g.
Does EGCG speed up metabolism?
Recent studies have shown that EGCG can increase brown fat thermogenesis in food-borne obese mice, thereby reducing fat accumulation and obesity response. At the same time, it can inhibit the inflammation of the hypothalamus mediated by microglia to protect the normal function of the central nervous system of body weight regulation.
Can I get EGCG by eating tea?
No, because tea contains phytic acid, ingesting too much phytic acid will stimulate the stomach. In addition, people with poor gastrointestinal function should not drink tea often, because tea contains caffeine, theophylline and other substances, which can excite the central nervous system and increase gastric activity, resulting in accelerated gastric motility, hypersecretion of gastric parietal cells, increased gastric acid, and gastric Mucosal irritation is strengthened, etc., which increases the burden on the gastrointestinal tract. Although EGCG is a good product for reducing fat and losing weight, it is not recommended to drink tea or eat tea directly, because this will not only achieve the effect of reducing fat, but also cause harm to the body.
