索氏法提取黑莓籽油工艺研究

Study on blackberry seed oil extraction technology by soxhlet methods

摘要: 以黑莓籽为原料,采用索氏法提取黑莓籽油。考察了溶剂性质、粉碎度、提取温度、提取时间及料液比对黑莓籽油出油率的影响。通过正交实验设计优化索氏法提取黑莓籽油的最佳工艺条件为:以石油醚为提取剂,黑莓籽粉碎过80目筛,提取时间2h,温度为90℃,料液比1:15(g:mL),在此条件下实验测得黑莓籽油平均出油率为22.855%。

Abstract: The blackberry seed oil was extracted by soxhlet methods from blackberry seed, and the effect of different solvents, grinding degree, extraction temperature, extraction time, solid-liquid ratio on the oil yield extraction were investigated.The optimal conditions were determined by orthogonal test as follows:benzine as solvents, grinding degree 80 mu, extraction temperature 90℃, extraction time 2h, solid-liquid ratio 1∶15 (g∶mL) .Under the optimal conditions, the yield of blackberry seed oil was 22.855%.
