摘　　要：为解决传统溶剂法提取葡萄籽油溶剂难回收、有毒、安全性差等问题,本研究以葡萄籽为原料,采用乙醇水提法水相循环重复提取葡萄籽油,研究乙醇体积分数、料液比、pH值、时间、温度等因素对提取率的影响,在此基础上进行正交试验,并对乙醇水提法提取的葡萄籽油品质进行研究。结果表明:通过正交试验优化出葡萄籽油提取最佳条件是乙醇体积分数45%、pH值9、温度70℃,在此条件组合下葡萄籽油提取率高达30.1%,且葡萄籽油品质接近或达到国家标准。乙醇提取法满足绿色提取工艺的特点,为葡萄籽油高效提取提供一种新思路。In order to solve the problems that solvent cannot be recovered,is poisonous,is not safe,etc when using traditional solvent method to extract grape seed oil,this paper took grape seed as the material,extracted grape seed oil in way of water-phase repeating with ethanol water extraction method and studied the influence of ethanol volume fraction,solid-liquid ratio,PH,time,temperature and other factors on extraction rate.On this basis,an orthogonal test was done and the quality of grape seed oil extracted with ethanol water extraction method was studied.The results showed the best conditions for extracting grape seed oil through orthogonal test optimization:ethanol volume fraction was 45%,pH was 9,and temperature was 70℃.Under these conditions,the extraction rate of grape seed oil reached up to 30.1%and the quality of grape seed oil approached or met national standard.Ethanol extraction method satisfies the characteristics of green extraction technology and provides a new idea to efficient extraction of grade seed oil.
