摘要
以中油杂10号菜籽为原料,研究了其冷榨油和混合溶剂浸提其冷榨饼后所得毛油的脂肪酸组成,并将经混合溶剂浸提后的菜粕与菜籽冷榨饼中的蛋白、硫甙含量进行了比较。结果表明,经不同混合溶剂浸提后得到的毛油脂肪酸组成有一定差异,浸提后的粕较冷榨饼中的蛋白提高了6%,硫甙脱除率最高达42.39%,筛选出石油醚-丙酮(v∶v=1∶1)混合溶剂是比较理想的浸提溶剂。
Using zhongyouza 10 rapeseed as raw material, the fatty acid composition of cold-pressed oil and mixed solvent extraction crude oil was studied in this paper.Cold-pressed rapeseed meal, rapeseed cake protein and glucosinolate content were compared.The results showed that different mixed solvent extraction of crude oil had different influences on fatty acid composition, extracted cold-pressed cake meal of protein increased 6%, the highest rate of glucosinolate removal attained 42.39%, number 3 mixed solvent was satisfied mixed solvent.
