| Abstract: | 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. |
