摘要: 为进一步探明烟熏灌肠类食品的风味特征,以哈尔滨红肠为对象,采用顶空固相微萃取制备样品,联合气质联用测定其主要挥发性物质。通过比较不同萃取头、萃取温度以及萃取时间对萃取效果的影响,获得较适的萃取条件:50/30μm DVB/CAR/PDMS萃取头、萃取温度50℃、萃取时间50min。采用气质联用对解吸物进行测定的结果表明,其挥发性风味物质的主要成分中醛类占17.59%、酮类占7.01%、酚类占7.27%、醇类占12.29%、烯萜类占9.39%、烷烃类占6.14%、含硫化合物占27.38%、杂环化合物占7.01%。

Abstract: The volatile flavor compounds in Harbin Sausage was extracted by head space solid phase microextraction (HS-SPME) technique and determined by capillary gas chromatography-mass spectrometry (GC-MS). The types of SPME fibers, extraction time, and extraction temperature were optimized in this study. The optimum extraction conditions were obtained as follows: 50/30μm DVB/CAR/PDMS fiber, adsorption time was 50min at 50℃. Aldehydes, ketones, phenols, alcohols, terpenes, alkanes, sulfur compounds and heterocyclic compounds were the major flavor compounds of Harbin Sausage with relative content of 17.59%, 7.01%, 7.27%, 12.29%, 9.39%, 6.14%, 27.38%, 7.01%, respectively.

Key words: head space solid phase microextraction, gas chromatography-mass spectrometry, volatile flavor compounds, harbin Sausage
