摘　　要：以大蒜为原料,采用溶剂法进行大蒜油提取,对影响大蒜油提取率的因素,如提取溶剂的选择、温度、时间及提取料液比等进行研究。确定了最佳提取条件:以95%乙醇作提取剂,每100 g大蒜泥中加入500 mL提取剂,提取温度90℃,提取时间为2.5 h,pH=6.5。同时,对提制的大蒜粗油进行了精制。Garlic oil was prepared from garlic by solvent extraction. The influences of factors such as extracting agents, ratio of garlic and extracting agent, extraction temperature and time, ect. on extraction ratio of garlic oil were examined. The optimum conditions were determined by orthogonal experiment. The optimum conditions were as follows ： extracting agent was ethanol（95%）, extraction temperature and time were 90 ℃ and 2.5 h, pH was 6.5, and 500 mL extracting agent was added in 100 g garlic.
