| 摘 要： | 卡诺拉油被认为是一种非常优良的食用油,但随着其品种的不断改良和改变,常温下混浊现象时有发生.采用气相色谱、红外光谱等方法,对沉淀物的理化常数、脂肪酸组成、脂肪醇组成等进行分析,得出沉淀物主要成分是蜡酯,少量的甘油三酯、杂质、游离脂肪酸,微量的皂、蛋白质、游离脂肪醇、烃等物质.

| Abstract: | Canola oil is considered to be an excellent edible oil.Over the past 10 years,however,the canola industry has seen the occasional appearance of haze or sediment in salad oil during storage in both refrigerator and store shelves.The physical and chemical properties,fatty acids and fatty alcohols of the sediment of canola oil were determined and discussed in detail.And the conclusion is drawn as following:the sediment of canola oil is mainly composed of wax esters,with small amount of hydrocarbons,triglycerides,free fatty acids(FFA) and alcohols(FAL),soaps and proteins. |
