Tea polyphenols is the first functional component found in tea. As a natural source of food antioxidants and functional ingredients, its fhnctional properties have been confirmed by many different research projects. The largescale preparation technology of tea polyphenols is becoming more and more mature, and the price of tea polyphenols is also gradually descending, which lays a foundation for the industrialization application of tea polyphenols in food industry. As a representative of green food additives and ingredients, its efficaey and activity include antioxidant, preservative, fresh-keeping, auxiliary color, etc. This paper reviewed the funetions of tea polyphenols and their derivatives and their application in food fresh-keeping processing, which provided necessary basis and value reference tbr the fhrther development of tea polyphenols series funetional ingredients.
