Function and Applications
Function and Application :
1. Meat products
Meat and its products often turn yellow due to the automatic oxidation of fat during storage, and appear rancid. During processing, the extract is added to inhibit the oxidative rancidity and bacterial growth on the surface of meat products and prevent spoilage. Good effect .
2. Edible animal and vegetable oils
Since animal fats do not contain natural antioxidants, they are easily oxidized and deteriorated. Adding tea polyphenols to oils can prevent and delay the automatic oxidation and decomposition of unsaturated fatty acids, effectively inhibit the oxidative rancidity of oils, prolong their storage period, and have an obvious effect on quality preservation and freshness. It is called "all-round refrigerator".
3. Fried food
Fried foods are prone to oxidative reactions, and tea polyphenols have a better antioxidant effect on fried foods, which can delay oxidative rancidity and increase the shelf life of foods. Baked food: In the production of moon cakes and other oily foods, adding tea polyphenols to the mixture of flour and oily items can not only solve the antisepsis of these foods, but also play a role in nutrition, health care and food flavor enhancement.
