摘要
考察了油菜籽中天然类胡萝卜素的提取工艺。通过单因素实验,研究了提取溶剂种类、料液比、原料粒径、提取温度、提取次数、提取时间等因素对类胡萝卜素提取率的影响。结果表明,提取油菜籽中天然类胡萝卜素的较优工艺条件为:提取溶剂为石油醚-丙酮(1∶1,v/v)混合溶剂,料液比(g/mL)为1∶30,原料粒径为100目,提取时间为6h,提取温度为40℃,提取次数为3次。
The extraction technology of carotenoid from rapeseed was studied in this paper.The effects of factors as solvent types ,solid-liquid ratio, granularity of material, extraction times and temperature on the extraction rate of carotenoid were examined through single factor experiment.The results showed that the best extraction conditions were as follows： petroleum ether-acetone（ 1： 1, v/v） as solvent, solid-liquid ratio （g/mL） was 1：30, the granularity of material was 100 mesh,extraction time was 6h, extraction temperature was 40℃, and extraction three times.
