3、高，进而对果实的抗氧化能力进行维持。苯丙烷类的代谢对葡萄果实中的多酚类物质的合成有密切影响，尤其是相关度最高的PAL和C4H。因此得出结论：10μmol/L核黄素处理能对葡萄果实苯丙烷类代谢酶活性的提高进行有效诱导，从而完成对果实多酚类物质合成的促进工作。关键词：葡萄，核黄素，苯丙烷类代谢2012 Bachelor’s Graduate of Department of Food Science & Technology, College of Life Science & Engineering of Chongqing Three Gorges Universi
4、ty ,Wanzhou, Chongqing, 404000Abstract:The experiment is to clear effect of Postharvest Treatment on antioxidant ability of riboflavin grape fruit during storage and decay rate.The PH difference method, Folin reagent method to measure the pH of grape fruit, total phenolic content data.
5、Through the data analysis, 10 mol / L riboflavin treatment on Postharvest grape fruit during storage of 1 DEG C total phenolics, total flavonoids and total anthocyanin content decreased to restrain.At the same time, the free radical scavenging ability and total reducing power were impr
6、oved, and the antioxidant ability was maintained.Closely affect the synthesis of phenylpropanoid metabolism of grape polyphenols in fruit, especially related to the highest degree of PAL and C4H.It is therefore concluded: 10umol / L riboflavin treatment of grape fruit phenylpropanoid m
7、etabolism enzyme activity to improve effectively induced, thus completing the fruit polyphenols synthesis to promote the work of.Keywords:Grapeberries,Methyljasmonate(VitaminB2),phenylpropnaoid1文献综述葡萄果实不仅是全球产量最大的浆果类水果，而且还具有“水果之神”的称号，其原产于地中海沿岸及美洲大陆，主要分布产于我国的新疆、河北、山东、四川等地。葡萄果实食用起来不仅有果鲜
