摘要
研究了混合溶剂一步法提取葡萄籽油和原花青素的工艺,试验结果显示最优工艺为料液比1∶7、混合溶剂正己烷/95%乙醇比例4∶6,提取温度65℃、提取时间3.5h,在此条件下葡萄籽油提取率为92.62%±3.74%,原花青素提取率为56.18%±4.12%。
The technology of extracting grape seed oil and procyanidin by mixed solvents is studied. The results show that the optimum condition is 1 ： 7 of the ratio of material and liquid, 4 ： 6 of the ratio of n-hexane and 95 % ethanol, 65 ℃ of the extraction temperature and extracting for 3.5 hours. Under the best condition, the extract yield of grape seed oil reaches 92.62% ＋ 3.74%, and the extract yield of procyanidin is 56.18% ＋4. 12%.
