摘要: 本实验用不同剂量的紫外光(UV-C和UV-B)对采后葡萄进行照射处理,并于不同的暗处理时间收集葡萄果皮,采用HPLC法分析其中白藜芦醇的含量。结果表明:UV-B对白藜芦醇的诱导作用不是很大,用UV-C照射20min暗处理48h后,白藜芦醇含量可提高15倍以上,鲜重达到155μg/g。因此可以考虑采用UV-C照射处理采后葡萄,把其作为高白藜芦醇含量的食物源。

Abstract: The effects of UV lights(UV-C and UV-B)on the radiation of resveratrol in the harvested grape peelings were examined.The resveratrol content was analyzed by HPLC.The results showed that UV-B has little effects on the content of resveratrol in grape peelings,whereas maximum resveratrol content(15-fold higher than untreated grapes) is achieved when irradiated 20 min with UV-C with 48 h darkness treatment.Therefore,the controlled UV-C irradiation pulses are useful as a simple postharvest treatment to obtain possible" functional" grapes with a dietary source of high resveratrol content.
