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
