Product Name:Tea extract
English Name:Tea extract
CAS No.:144207-58-9
Aliases:Tea polyphenols, Green tea extract
Molecular Formula:C36H32O21
Physical Properties:This product appears as brownish-yellow or light yellow powder with a characteristic tea aroma and a bitter taste. It is readily soluble in water and ethanol, slightly soluble in ethyl acetate, and insoluble in chloroform and petroleum ether. Its aqueous solution is weakly acidic (pH 4–6). It is prone to oxidative discoloration under light and high temperature, and should be stored sealed and protected from light. The molecular weight is 800.63.
Uses:Tea extract is rich in tea polyphenols and other bioactive components. It is a natural and powerful antioxidant commonly used in oils and oil-containing foods to prevent oxidative rancidity. In health foods and cosmetics, it is utilized to scavenge free radicals, delay aging, and whiten the skin. It is also widely applied in pharmaceutical fields for its antibacterial, anti-inflammatory, and lipid-lowering effects.
Technical Specifications:
The product is a brownish-yellow or light yellow powder with a characteristic tea aroma.
The content of tea polyphenols is not less than 98%, with catechins accounting for over 70% of the total polyphenols.
Moisture and volatile matter content is ≤5%, and residue on ignition is ≤2%.
The pH of the aqueous solution is 4.0–6.0, and the product is readily soluble in water and ethanol.
It should be stored sealed in a cool, dry, dark place, with a shelf life of 24 months.
