Effects of degumming processes on rapeseed oil quality and composition of phospholipids in oil sediment
摘要
Abstract
The changes of acid value,peroxide value,phosphorus content,phytosterols,tocopherols and diglyc-erides of rapeseed oil,as well as the composition and content of phospholipids in degummed oil feet(oil sediment)were investigated under different degumming conditions using rapeseed crude oil as raw material.There were signif-icant differences in degumming capabilities among water degumming and enzymatic degumming,enzymatic degum-ming showed more competence than water degumming,meanwhile,phospholipase A1 enzymatic degumming was more thorough compared with that of phospholipase C.The peroxide value and acid value of rapeseed oil showed a decreasing trend after degumming,additionally,the acid value of phospholipase A1 decreased the least.The content of tocopherols and phytosterols in degummed oil decreased slightly,with a maximum decrease of about 5%.Diacylg-lycerols content in phospholipase C enzymatic degumming increased significantly,meanwhile,the ratio of 1,3-diac-ylglycerols to 1,2-diacylglycerols in degummed oil decreased,with the ratio ranging from(2.2-3.0):1.There were significant differences in the composition and content of phospholipids in degummed oil feet after different degum-ming processes,which phospholipase A1 enzymatic degumming oil feet owned the highest content of lysophospholip-ids,and phospholipase C enzymatic degumming oil feet had the highest content of phosphatidylinositol.关键词
