What is Green Tea Extract Polyphenols?
Green tea extract polyphenols is a general term for polyphenols in tea. It is an amorphous powder and is easily soluble in water. 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 depsid acids Class 6 compounds. Among them, flavanones (mainly catechin compounds) are the most important, accounting for 60% to 80% of the total tea polyphenols, followed by flavonoids, and other phenolic substances are relatively small. Tea polyphenols have many physiological activities such as anti-oxidation, anti-radiation, anti-aging, lowering blood fat, lowering blood sugar, inhibiting bacteria and enzymes.
Application in the food industry
1. Used as an antioxidant
Green tea extract polyphenols are used as antioxidants. Since most of the tea polyphenols contain more than two ortho-hydroxy polyphenols and have strong hydrogen supply capacity, they are an ideal antioxidant. Among the four main catechins, the antioxidant capacity is EGCG>EGC>ECG>EC. As an antioxidant for oily foods, it has excellent antioxidant properties, and its effectiveness is far superior to the synthetic antioxidants 2,6-di-tert-butyl-4-methylphenol (BHT) and butylhydroxy fennel (BHA). The antioxidant effect of tea polyphenols can be applied to meat product processing, oil storage, baked food, dairy products, fried food, and various beverage preparations. When freezing fresh fish, adding tea polyphenol antioxidants can prevent the oxidation of fish body fat.
2. Used as a food preservative
Tea polyphenols have inhibitory activity against nearly 100 kinds of bacteria in the natural world, show broad-spectrum antibacterial properties, and are good food preservatives. As a fresh-keeping agent, tea polyphenols can slow down the biochemical activities of fruits and vegetables after picking, and postpone the subsequent ripening period. In addition, the antistaling agent formulated with tea polyphenols can also prevent color change and corruption during the deep processing of various pastries, lactic acid beverages and livestock products.
3. Used as food color retention agent
The oxidation of the same pigment can change the color of food. Tea polyphenols have strong reducing properties and can prevent natural pigments (such as carotene, chlorophyll, safflower yellow, vitamins and carmine, etc.) from being fading due to photooxidation. Stability has a certain effect.
