【摘要】 采用超微粉碎技术对菘蓝种子进行处理,得到不同粒径的粉体,用正己烷溶剂浸提菘蓝种子油。结果表明,物料粒径对提取率的影响显著,超微粉碎有利于菘蓝种子油的提取。以物料颗粒平均直径为7.96μm,粉体比表面积0.84 m2/mL的菘蓝种子超微粉为原料,在料液比1∶12,浸提温度85℃,浸提时间1 h条件下,菘蓝种子油的提取率最大,为27.05%。更多还原

【Abstract】 Different diameter powders of Isatisl indigotica Fort.seed obtained by superfine communication technique were used as materials to extract the oil by n-hexane.The result showed that the effect of material partical size was significant on extraction rate,and superfine communication was beneficial to oil extraction.The optimal conditions were as follows:powder diameter 7.96 μm,the specific surface area of powder 0.84 m2/mL,ratio of material to liquid 1∶ 12,extraction temperature 85 ℃,extraction time 1 h.Under the optimal conditions,the extraction rate was 27.05%.更多还原
