密集烘烤工艺对烟叶多酚类物质含量及PPO活性的影响
Effects of different bulk curing technologies on polyphenol content and PPO activity in tobacco leaves
摘要
Abstract
Dynamic changes of polyphenol substance contents and PPO activity during 3 different curing processes were studied using electric-heated flue-curing barn. Results showed that content of total phenols, chlorogenic acid, new chlorogenic acid, implicit chlorogenic acid, and Rutin increased during all curing processes. After curing, K2 treatment resulted in the highest content of total phenols, chlorogenic acid, new chlorogenic acid, and implicit chlorogenic acid, while K3 treatment resulted in the highest content of rutin and scopoletin. K2 treatment showed the lowest PPO activity during the sensitive period (45℃-47℃) of the brown reaction while K3 treatment showed the highest. Those indicated that K2 treatment can effectively inhibit enzymatic browning reaction and regulate polyphenol content during bulk curing, and produced higher level of polyphenol substances after curing.关键词
