摘要
以辣木籽为原料,分别采用索氏抽提法、乙醇水法和水酶法提取辣木籽油,研究脱胶工艺对3种提取方法得到的辣木籽油品质的影响。结果表明:脱胶对3种方法提取辣木籽油的色泽和透明度影响较大,而对其气味影响不大;脱胶能够降低毛油中的酸价、叶绿素和类胡萝卜素含量;增加毛油的碘值、氧化诱导时间;3种方法提取的辣木籽油脱胶前后酸价、碘值、氧化诱导时间、叶绿素和类胡萝卜素含量有显著性差异;3种提取方法得到的辣木籽毛油中脂肪酸成分无显著性差异,均有15种脂肪酸组成且含量最高的脂肪酸均为油酸,脱胶前后3种提取方法得到的辣木籽油中脂肪酸含量也无显著性差异。故脱胶能够适当提高油脂的氧化稳定性,提高油脂品质。
Moringa seed oil was extracted from Moringa seeds by Soxhlet extraction method, ethanol-water method and aqueous enzymatic method, respectively, and the effect of degumming on the quality of Moringa seed oil extracted by three methods were researched. The results showed that degumming had great effects on the color and transparency of Moringa seed oil extracted by three methods, but had little effects on its odor. Degumming could reduce the acid value, the chorophyll and carotinoid content in crude oil, and increased the iodine vale and oxidation induction time of the crude oil. There were significant differences among the acid value, iodine value, oxidation induction time, chorophyll and carotinoid of Moringa seed oil extracted by three methods before and after degumming. There were no significant differences in fatty acid composition of Moringa seed oil extracted by three methods, all of which were composed of fifteen fatty acid compositions, and the fatty acid with the highest content was oleic acid. There were no significant differences on the fatty acid content of Moring seed oilextracted by three methods before and after degumming. Therefore, degumming can appropriately improve the oxidative stability and quality of the grease.
