摘要: 采用顶空固相微萃取分别对原料全脂牛乳、巴氏灭菌全脂牛乳和超高温灭菌全脂牛乳的挥发性成分进行 萃取,经气相色谱-质谱联用仪分析。结果显示,原料全脂牛乳中共鉴定出12 种挥发性物质,主要包括酸类和烷烃 类;巴氏灭菌全脂牛乳中共鉴定出17 种挥发性物质,主要包括酸类、酯类、酮类和烷烃类;超高温灭菌全脂牛乳 中共鉴定出17 种挥发性物质,主要包括酸类、酮类和烷烃类。经数据统计分析,3 种牛乳样品的挥发性组分呈现明 显差异。

Abstract: The volatile flavor compounds of raw whole milk (RWM), pasteurized whole milk (PWM) and ultra-hightemperature whole milk (UWM) were extracted by headspace solid-phase micro-extraction, and then analyzed by gas chromatography-mass spectrometry (HS-SPME-GC-MS). A total of 12 volatiles were identified from RWM, mainly including acids and hydrocarbons; 17 volatiles were identified from PWM, mainly including acids, esters, ketones and hydrocarbons; and 17 volatiles were identified from UWM, mainly including acids, ketones and hydrocarbons. According to the statistical analysis of the data, there was a significant variability among the volatiles of 3 milk samples.

Key words: raw whole milk, pasteurized whole milk, ultra-high-temperature (UHT) whole milk, volatile flavor compound
