摘要
首先采用不同溶剂提取花椒油,确定石油醚为最佳提取溶剂。在此基础上,通过正交试验对花椒籽油的提取工艺进行了优化,结果得出最佳的工艺条件为:以石油醚为提取溶剂,在料液比1∶13,提取温度60℃下,提取2次,每次2 h。在此工艺条件下,花椒籽油的提取率达到90%以上。同时利用气相色谱对花椒籽油的脂肪酸组成进行了测定,结果表明,花椒籽油中以油酸和亚油酸含量最高,最少为棕榈油酸。
Prickly ash seed oil was first extracted by different solvents to determine the optimal one,and the result showed that petroleum ether was the best.After that,on the basis of single factor experiment,the orthogonal test was used in optimization of technological parameters.The optimum technological condition was that prickly ash seed was extracted by petroleum ether at the ratio of 1(material)∶13(petroleum ether) and 60℃ for 2 times and 2 hours per time,under which the extracted rate could be as high as 90%....
