以文冠果籽为原料,利用热盐水法提取文冠果籽油。通过响应面法优化提取工艺,建立影响文冠果油提取率的因素与响应值之间的数学模型,并采用GC-MS分析其脂肪酸组成。结果表明:当搅拌转速40 r/min,NaCl加入量10%,料液比1∶3.5(g∶mL)时,油脂提取率可达70.06%,与模型高度拟合;GC-MS分析确定文冠果中主要含8种脂肪酸,其中必需脂肪酸亚油酸含量高达42.83%。

With the Xanthoceras sorbifolia seeds oil was extracted via hot salt water method.Mathematical model between the primary factors and respond value was built by respond surface method and GC-MS fatty acid composition analysis.The results showed that when the stirring speed was 40 r / min,the dosage of NaCl was 10%,material liquid ratio was 1∶ 3.5(g∶ mL),the oil extraction rate can reach to 70.06% and it is highly consisted with the mathematical model;GC-MS analysis showed that the seed oil mainly contained 8 fatty acids.Among them,linoleic acid,one essential fatty acid was up to 42.83%.
