摘要:

以清真酱牛肉为研究对象,分析加工过程中挥发性风味物质的变化规律。利用固相微萃取-气相色谱-质谱联用结合嗅闻技术,分别对预煮、煮制1 h、煮制完成和浸泡冷却后的酱牛肉样品4 个阶段的挥发性风味物质进行定性定量分析。结果表明,清真酱牛肉加工过程中共鉴定出103 种挥发性风味物质,4 个阶段样品的挥发性风味物质种类数量分别为46、51、58 种和54 种,4 个阶段共有的风味化合物为18 种;加工过程中醛类、醚类、含氮含硫及杂环化合物相对含量呈增加趋势,酯类物质相对含量随加热逐渐下降,醇类、酮类和酸类物质相对含量无明显变化。

Abstract:

In this study, the changes in volatile flavor components in islamic spiced beef at different processing steps were
analyzed. The volatile flavor components in samples from pre-cooking, cooking for 1 h, complete cooking, and cooling were
extracted and identified by solid phase micro-extraction coupled with gas chromatography-olfactometry-mass spectrometry
(SPME-GC-O-MS). The results showed that a total of 103 volatile compounds were identified in islamic spiced beef during
processing, 18 of which were detected in all 4 processing steps. The numbers of volatile compounds in the 4 processing
steps were 46, 51, 58 and 54, respectively. The relative contents of aldehydes, ethers, nitrogen- and sulfur-containing and
heterocyclic compounds significantly increased, while esters gradually declined. However, the contents of alcohols, ketones
and acids did not change obviously during processing.

Key words: islamic spiced beef, processing, volatile flavor components, traditional Chinese meat products
