摘  要:
以巨峰葡萄品种为试材,对葡萄果皮中色素的提取条件进行了探讨。结果表明:70%乙醇+0.5%柠檬酸(体积比5∶1)提取葡萄果皮色素的效率最高,其次是80%乙醇+0.5%柠檬酸(5∶1);以70%乙醇+0.5%柠檬酸(5∶1)为提取液,葡萄果皮质量与提取液的料液比宜为1∶10(g/mL),最适宜温度为65℃,最佳提取时间为90 min,提取最适pH 2.0。

摘  要:
The study is the conditions for the extraction of proanthocyanidin from Jufeng grape skins.The results showed that: with 70% ethanol+0.5% citric acid(5∶1) the highest extraction efficiency,followed by 80% ethanol+0.5% citric acid(volume ratio 5∶1).And the ratio of grape pomace and extraction being 1∶10(g/mL),the most appropriate temperature was 65℃,the best extraction time was 90 min,the most appropriate pH was 2.0.
