咖啡渣油脂的提取及其脂肪酸组成研究

Extraction of coffee oil from coffee grounds and analysis of its fatty acid composition

加工咖啡时剩下的残渣可用来提取天然植物油脂。用气-质联用仪分析咖啡油的组成,测出4种主要脂肪酸:亚油酸34.79%、油酸9.85%、棕榈酸42.12%、硬脂酸8.49%,油的脂肪酸组成较好,故咖啡油有一定的营养保健作用。

Coffee oil can be extracted from spent coffee ground. There are four components of fatty acid in coffee oil by GC-MS-MSD analysis. They are linoleic acid（34.79%）, linolenic acid（9.85%）, palmitic acid（42.12%）, and stearic acid（8.49%）. This oil has higher value in medical health protection.
