During the extraction process, due to the oxidative polymerization of a small amount of tea polyphenols, they appear pale yellow to brown, with a slight tea fragrance and astringency; ￭Easily soluble in ethanol, methanol, ethyl acetate, acetone, etc., slightly soluble in oil, insoluble in organic solvents such as benzene and chloroform; ￭It has good heat resistance, has hygroscopicity, is stable at pH 2 to 7, and is easy to oxidative polymerization under the conditions of light or pH >8. ￭Can form green-black compounds with iron ions |
| Description | Tea polyphenols is a general term for polyphenols in tea. It is a white amorphous powder. It is a complex of polyhydroxy phenolic compounds in tea. It is composed of more than 30 phenolic substances. Derivatives are the main chemical components in tea with health care functions. The content of tea polyphenols in green tea is relatively high, accounting for 15% to 30% of its mass. The main components of tea polyphenols are: flavanones, anthocyanins, flavonols and anthocyanins, phenolic acids and depsidic acids Class 6 compounds. |

| Food & Beverage | ￭Anti-oxidant It has a strong hydrogen supply capacity, so it is an ideal antioxidant ￭Food preservative Tea polyphenols have inhibitory activity against nearly 100 kinds of bacteria in nature, showing broad-spectrum antibacterial properties, and are good food preservatives. ￭Food color retention agent Oxidation of the same pigment can change the color of food. Tea polyphenols have strong reducing properties, which can prevent natural pigments from fading due to photooxidation, and have a certain effect on the stability of pigments. ￭Food deodorant Bad breath is mainly caused by volatile sulfur-containing compounds and nitrogen-containing compounds, among which sulfides such as hydrogen sulfide and methyl mercaptan have the heaviest odor. Chewing gum containing tea polyphenols is 10 times more deodorant than ordinary chewing gum |
| Dietary Supplemets | ￭Anti-oxidation Tea polyphenol is an excellent natural antioxidant, and its antioxidant properties are closely related to the synergistic effect of each component ￭Blood lipid Tea polyphenols can comprehensively adjust blood lipids, especially reduce serum TG (triglyceride), TC (total cholesterol) and low-density lipoprotein cholesterol (LDL-C) levels, and increase high-density lipoprotein cholesterol. ￭Antiviral and antibacterial effects As a broad-spectrum, potent and low-toxic antibacterial drug, tea polyphenols have been recognized by scholars from many countries in the world. ￭Antitumor effect It can inhibit the synthesis of DNA in tumor cells and further inhibit the growth and proliferation of tumors ￭Inhibit arteriosclerosis. Drinking tea can improve the ratio of cholesterol in the blood and achieve the effect of preventing cardiovascular disease ￭Hypoglycemic effect Tea polyphenols have inhibitory effects on the activities of amylase and sucrase in humans and animals. Among them, theaflavins have the best effect. |
