Abstract:

In order to optimize the extraction conditions of chilled pork, the volatile components in chilled pork were extracted by solid phase micro-extraction (SPME) and determined by gas chromatography-mass spectrometry (GC-MS). The volatile components in chilled pork were analyzed during the various storage temperatures and time. Results indicated that the optimal SPME conditions was extraction using a 65 μm PDMS/DVB fiber at 35 ℃ for 40 min. Totally 25 volatile compounds were identified and the relative contents of trimethylamine and alcohols were increased with the extension of storage time.

Key words: chilled pork, solid phase micro-extraction (SPME), gas chromatography-mass spectrometry (GC-MS), volatile components
