As the name suggests,tea polyphenols are the general term of polyphenols in tea,and their essence is white powder.The content of tea polyphenols in green tea is high,accounting for 15%~30%of its quality.The main components of tea polyphenols are:flavanols,flower pigments,flavonols and gray pigment,and 6 compounds of phenolic acid and phenolic acid. What are the physicochemical properties of tea polyphenols? Pure tea polyphenols are white amorphous crystalline substances,which appear light yellow to brown because of a small amount of tea polyphenols in the extraction process,slightly with tea fragrance and astringent taste Tea polyphenols are easily soluble in water,ethanol,ethyl acetate,slightly soluble in oil,difficult to dissolve in benzene,chloroform,etc. Unstable in alkaline media and prone to oxidation and browning. What is the mechanism of action of tea polyphenols antioxidant? The acidic hydroxyl group in the structure of catechins and its derivatives has hydrogen supply activity,which can provide hydrogen atoms to the peroxidation free groups of unsaturated fatty acids to form hydroperoxides,preventing the fatty acids from forming new free groups,thus interrupting the lipid oxidation process. The amount of tea polyphenols should be moderate,because the peroxyl free radicals produced by the antioxidant components themselves can also induce the chain reaction of free radicals. The effectiveness of tea polyphenols as antioxidants in skin care The reason why tea polyphenols can play a deep moisturizing role is because tea polyphenols contain polyol structure,which can absorb water in the air. In terms of anti-aging,tea polyphenols can prevent the decline or degeneration of elastin content to maintain skin elasticity.Another function of tea polyphenols is to have a certain effect of convergence and reduce oil secretion.
