摘要:

以真空包装和散装2 种包装方式、秋季和冬季生产的重庆城口腊肉为研究对象,采用顶空固相微萃取和气相色谱-质谱联用技术分析重庆城口腊肉的挥发性风味成分。结果表明:在相同的生产季节,不同包装方式的腊肉样品中酯类、酚类和碳氢化合物相对含量变化明显,醛类和醇类物质相对含量变化不明显。在相同的包装条件下,不同季节生产的腊肉样品中酚类和碳氢化合物相对含量变化明显,酯类、醛类和醇类物质相对含量变化不明显。此外,腊肉的特征性挥发风味成分主要来自于酚类、醇类、醛类等,如3-甲基愈创木酚、4-甲基愈创木酚、愈创木酚、2,5-二甲基苯酚、己酸甲酯、甲苯酸丁酸酯、正己酸乙酯等。

Abstract:

The volatile flavor compounds of bulk and vacuum packaged Chongqing Chengkou bacons produced in autumn
and winter, respectively, were extracted by solid-phase micro-extraction (SPME) and analyzed by gas chromatography
and mass-spectrometry (GC-MS). The results showed that in the same production season, the contents of esters, phenolics
and hydrocarbon of bacons with different packaging treatments changed obviously while the changes in aldehydes and alcohols
were not obvious. Under the same packaging treatment, the contents of phenols and hydrocarbon in bacons produced in different
seasons changed markedly but no significant changes in the contents of esters, aldehydes and alcohols were found. In addition, the
characteristic volatile flavor of bacon was mainly derived from phenols, alcohols and aldehydes, such as 3-methyl guaiacol, 4-methyl
guaiacol, guaiacol, 2,5-dimethylphenol, caproate, benzoic acid butyrate, ethyl caproate, and so on.

Key words: Chongqing Chengkou bacon, volatile flavor compounds, solid-phase micro-extraction (SPME), gas chromatography-mass spectrometry (GC-MS)
