摘要:

以兔背最长肌为研究对象,采用顶空固相微萃取结合气相色谱-质谱联用技术,分别对兔背最长肌在冷藏过程中的挥发性风味物质进行定量、定性分析。结果表明:在冷藏过程中检测到兔背最长肌挥发性风味物质共79 种,其中醛类19 种、酮类4 种、醇类17 种、酯类6 种、烃类31 种、呋喃类2 种,且醛类化合物所占的比重最高,其次是醇类及烃类化合物,酮类、酯类及呋喃类化合物在挥发性物质中所占的种类少含量低。随着冷藏时间的延长,兔背肉中各类挥发性风味物质的种类和相对含量也不断变化,其中醛类、醇类及烃类物质的变化差异大,酯类、酮类和呋喃类随时间变化不明显。

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
