In order to discuss the oxidation resistance function of tea polyphenol in fish product, different dosages of tea polyphenol were applied in the refrigerated fish flake, and then acid value, peroxide value, MDA content of the lipid were tested. The results indicated that in the fish product, the oxidation rate of lipid presented the situation of fast-slow-fast, and the different dosages of tea polyphenol all showed a good oxidation resistance to the refrigerated fish flake; it can add 0.01%~0.03% tea polyphenol in the refrigerated fish flake f...
