摘要/Abstract

摘要： 为了对目前消费市场流行的液态奶制品挥发性成分进行分析检测,本文采用在60℃的恒温水浴中,加热装于医用输液瓶中的液态奶制品,取上层气体作色谱分析。液态奶制品挥发性组分在5%PEG-20M色谱柱上,通过程序升温得到了较好的分离,并用标准物质对照定性。结果表明液态奶制品的挥发性成分主要有乙醛、乙醇、异戊醇、甲酸乙酯、乙酸乙酯、乙酸异丁酯、乙酸异戊酯和乙酸正丁酯等。不同产品,其挥发性组分略有差异。

关键词: 液态奶制品, 挥发性成分, 气相色谱

Abstract: In this paper, in order to analyze the volatile compositions of popular liquid milk product in market of food consume at present, we heated the liquid milk product in medical liquid transfer bottle by using constant temperature bath, and have done chromatographic analysis to top gas. The volatile compositions were speparated perfectly in 5% PEG-20M chromatographic column by using temperature programming, and qualitative test was performed by referencing standard substance. The results showed that the volatile compositions in liquid milk product contained mostly aldehyde, alcohol, isoamyl alcohol, ethyl formate, acetic ether, isobutyl acetate, isoamyl acetate, n-butyl acetate. Those substances have a little differences in different liquid milk products.
