The effects of tea polyphenols (TP) on post-harvest preservation of flat peaches were studied. The results showed that TP could restrain peaches from browning and dehydration; delay the loss of soluble solids contents (SSC); postpone fruit softening and the loss of vitamin C (Vc)significantly. It could also reduce the production of malondialdehyde (MDA) and regulate polyphenol oxidase (PPO) activity. Therefore, TP treatment could delay aging and decay of peach and extend its storage period. An alcohol extraction liquor of tea also showed freshness-keeping effect on flat peach. The possible mechanism of the preservation effects is that TP has good antioxidation effects and can slow down oxidative damage; regulate PPO activeness and activate defense systems of flat peach.
