气质联用法分析赤霞珠干红葡萄酒中脂肪酸

摘要

采用气质联用法（GC/MS法）分析赤霞珠干红葡萄酒中脂肪酸组成，样品用正己烷提取，氢氧化钾-甲醇法甲酯化，归一化法计算含量。结果显示，干红葡萄酒中主要含有己酸、辛酸、十一烷酸、月桂酸、肉豆蔻酸、肉豆蔻烯酸、十五烷酸、棕榈酸、棕榈油酸、十七烷酸、十七碳烯酸、硬脂酸、油酸、反油酸、亚油酸、亚麻酸、花生酸、花生一烯酸、山嵛酸、顺-13，16-二十二碳二烯酸、二十二碳五烯酸、神经酸、木焦油酸等23种脂肪酸。%The chemical composition and contents of fatty acid in cabernet sauvignon wines was determined by GC/MS. The GC/MS detection showed containing 23 kinds of fatty acid, such as:hexanoic acid,caprylic acid, undecanoic acid,lauric acid,myristic acid,myristoleic acid,pentadecanoic acid,palmitic acid,palmitoleic acid,heptadecanoic acid,heptadecenoic acid,stearic acid,oleic acid,elaidic acid,linoleic acid,linolenic acid, arachidic acid,eicosatrienoic acid,behenic acid,docosadienoic acid,DPA,nervonic acid,lignoceric acid.
