| 摘 要： | 本文对已报道的苹果多酚物质进行了归类。并列出了它们的结构图。在苹果加工业中，褐变备受关注，其直接影响着产品的营养、风味和感官。这种褐变主要由于多酚类物质在西每（多酚氧化酶PPO和过氧化酶POD）的氧化下生成了有色物质，文中对这两种酶氧化多酚机理进行了分析，并时褐变抑制剂及抑制机理作了阐述。

| Abstract: | Recent advances in apple polyphenol were reviewed. Firstly we classified the apple polyphenol which had been reported, and their structures were shown. Because the browning plaied an important roles in apple industries, such as effect of the nutrition, flavor and organoleptic property, then paid more attention. The browning was caused by the oxidation in the present of apple polyphenol oxidase or peroxidase. In the process, the colourful pigment is produced. We analyzed the reaction mechanisms of browning and inhibition of browning, also recount the inhibitors of browning and browning mechanism. |
