Function of Green Tea Extract Polyphenols
1 antioxidant
The effective antioxidant ingredient in tea polyphenols (green tea extract) is stable to heat and acid, and has the characteristics of natural, non-toxic and efficient capture of water-soluble free radicals. Typical Polyhydroxyphenol antioxidants have strong hydrogen supply capacity, can interrupt the chain reaction of hydroperoxides generated by automatic oxidation, and form stable compounds by themselves, thus blocking the oxidation process.
2 tooth cleaning
Tea polyphenols (green tea extract) can kill lactic acid bacteria and other dental caries bacteria in pet teeth. It can inhibit the activity of glucose polymerase, so that glucose cannot polymerize on the surface of bacteria, so that bacteria cannot be implanted on teeth, and the process of dental caries formation is interrupted; The residual proteins in the teeth become the matrix for the appreciation of spoilage bacteria. Tea polyphenols can kill such bacteria, so it can remove pet halitosis, reduce dental plaque, reduce the occurrence of dental calculus and periodontitis.
3 protect the heart
For the imbalance of the body's antioxidant system caused by exercise, tea polyphenols is a very effective antioxidant supplement. Tea polyphenols can produce a superposition effect on free radical damage caused by moderate intensity exercise, and the superposition effect is more obvious in the heart.
Application of green tea extract (tea polyphenols) in food
1. Meat products
Meat and its products often turn yellow and sour due to the automatic oxidation of fat during storage. In the process of processing, the extract is added to achieve the good effect of inhibiting the oxidative rancidity and bacterial growth on the surface of meat products and preventing corruption.
2. Edible animal and vegetable oils
Animal fats and oils are easy to deteriorate due to their lack of natural antioxidants. Adding tea polyphenols to oil can prevent and delay the automatic oxidative decomposition of unsaturated fatty acids, effectively inhibit the oxidative rancidity of oil, extend its storage period, and have an obvious effect on quality and preservation, which is known as "universal refrigerator".
3. Fried food
Fried food is prone to oxidation reaction. Tea polyphenols have a relatively good antioxidant effect on fried food, which can delay the phenomenon of oxidative rancidity and improve the shelf life of food.
4. baked food
In the production of moon cakes and other oil-bearing foods, adding tea polyphenols to the mixture of flour and oil-bearing items can not only solve the problem of anti-corrosion of these foods, but also play a role in nutrition, health care and improving food flavor.
5. beverages
Tea polyphenols can be used to prepare various tea beverages and applied to various alcoholic beverages. It can also inhibit the destruction of vitamin A and vitamins and other vitamins in soymilk, soda, fruit juice and other beverages, and maintain the nutritional composition.
