乙醇水剂法提取野山杏仁油及组成成分分析研究

摘要

利用乙醇水剂法提取野山杏仁油,通过单因素实验结合响应面优化确定的最佳提取工艺是:乙醇浓度18%,料液比1:7g/mL,温度34℃,搅拌转速120r/min,提取时间120min.在此条件下,油脂提取率为28.34%,亚油酸和油酸含量分别为23.72%,66.47%,抗氧化能力较强.%Wild almond oil was extracted by ethanol aqueous method.The optimum extraction process was determined by single factor experiment and response surface optimization:ethanol concentration 18%,solid-liquid ratio of 1:7 g/mL at a temperature of 34 ℃,stirring speed 120 r/min,extraction time 120 min,the oil extraction rate was 28.34%,linoleic acid and oleic acid contents were 23.72%and 66.47%,antioxidant capacity is strong.
