由小麦胚芽提取天然生育酚的研究

Extraction of Natural Tocopherols from wheat Germ

摘要:

经热处理以钝化脂肪氧化酶，进行了小麦胚芽提取天然生育酚的实验和研究。用９５％的乙醇水溶液浸出小麦胚芽，浸出液经脱溶、浓缩和精制处理，得到天然生育酚浓缩物，其生育酚总含量为２１５３．２ｍｇ／１００ｇ；用石油醚浸出小麦胚芽得到毛油，毛油经精炼得精炼胚芽油，在高真空和高温下脱臭得脱臭馏出物，脱臭馏出物经一系列精制处理得到天然生育酚浓缩物，其生育酚总含量为２０６７．６ｍｇ／１００ｇ。

Abstract:

Extraction of germ is reported. After heat treatment of wheat germ for inactivating lipoxidase,wheat germ was extracted by aqueous ethanol(95%w/w).The extractmixture was desolvented,concentrated and purified by a series of treatment.Thus the natural tocop
