Introduction to Tea polyphenols
Green Tea Polyphenols (abbreviated as GTP), also known as antioxidants, vitamins and polyphenols, is a complex of polyhydroxyphenolic compounds in tea. It is composed of more than 30 kinds of phenolic substances. Its main body is The ingredients are catechins and their derivatives, which are the main chemical components with health-care functions in tea. Tea polyphenols have various physiological activities such as antioxidant, radiation protection, anti-aging, lowering blood lipids, lowering blood sugar, inhibiting bacteria and enzymes, etc.
Physical and chemical properties of Tea Polyphenols
Pure Tea Polyphenols are white amorphous crystalline substances. During the extraction process, due to the oxidation and polymerization of a small amount of tea polyphenols, they appear light yellow to brown, with a slight tea aroma and an astringent taste; they are easily soluble in ethanol, methanol, and ethyl acetate. , acetone, etc., slightly soluble in grease, insoluble in organic solvents such as benzene and chloroform; good heat resistance, hygroscopic, stable at pH 2 to 7, and easy to oxidize and polymerize under light or pH > 8 conditions. It can form green-black compounds with iron ions.
Extraction method of Tea Polyphenols
Organic solvent extraction method
This is one of the most widely used methods. The principle is to utilize the solubility differences of different compounds in tea leaves in different solvents for extraction and separation. This method is relatively simple, and the extraction rate of tea polyphenols is 10% to 15%.
Adsorption separation and extraction method
Extract the green tea leaves with heated water three times and combine the extracts. The tea extract is adsorbed by a polymer adsorbent, and then eluted with a 95% ethanol solution to desorb the GTP adsorbed on the adsorbent into ethanol. The ethanol is recovered through vacuum distillation, and the concentrated solution is vacuum dried or spray dried to obtain tea. polyphenols.
Supercritical Fluid Extraction
Supercritical fluid extraction (SFE) is a new separation technology that uses a fluid with a temperature and pressure slightly above or close to the critical temperature and critical pressure between gas and liquid as an extraction agent to extract certain substances from solids or liquids. High boiling point and heat-sensitive components to achieve the purpose of separation and purification. Since its medium is usually non-toxic carbon dioxide, it is not toxic to the products and is particularly suitable for the extraction of medicines, food additives and other products.

Applications of Tea polyphenols
Tea polyphenols is the general name for polyphenols in tea and is the main active ingredient in tea. Tea polyphenols not only have antioxidant, anti-free radical, anti-radiation, anti-allergic effects, but also have anti-bacterial and anti-inflammatory properties, and can remove harmful toxins produced by human metabolism. Substances and anti-aging and other health functions. At present, research at home and abroad has proven that tea polyphenols have multiple functions such as preventing arteriosclerosis, antibacterial and anti-inflammatory, weight loss and bodybuilding, preventing cardiovascular diseases, and inhibiting tumors.
