Abstract:

Headspace solid phase microextraction (HS-SPME) combined with gas chromatography-mass spectrometry (GCMS)
was used for the quantitative and qualitative analysis of volatile flavor compounds in rabbit longissimus dorsi during
cold storage. The results showed that 79 volatile flavor compounds including 19 kinds of aldehydes, 4 kinds of alcohols,
17 kinds of alcohols, 6 kinds of esters, 31 kinds of hydrocarbons and 2 kinds of furans were detected, and the highest
proportion was aldehydes, followed by alcohol and hydrocarbons, and the numbers and amounts of ketones, esters and
furans compounds were lower. The types and relative contents of volatile flavor compounds changed with storage time, with
particularly marked changes in aldehydes, alcohols and hydrocarbons yet no significant changes in esters, ketones or furans.

Key words: rabbit longissimus dorsi, headspace solid phase micro-extraction (HS-SPME), gas chromatography-mass spectrometry (GC-MS), volatile flavor compounds
