摘要:

挥发性成分是决定香菇香气品质的关键。研究采用顶空固相微萃取(HS-SPME)结合气相质谱联用(GC-MS)对冷冻干燥(FD)、低温恒温干燥(LD)、高温恒温干燥(HD)和红外干燥(ID)加工的香菇进行挥发性成分分析。结果表明,从4种工艺香菇中共鉴定出48种挥发性成分。通过对4种工艺香菇总挥发性成分和各类挥发性成分进行比较分析,发现HD和ID工艺香菇总挥发性成分、醛类和含硫化合物含量高于LD和FD工艺香菇。进一步比对4种工艺香菇各类挥发性成分差异,发现HD和ID工艺香菇中重要香气物质二甲基三硫、1,2,4-三硫杂戊烷和香菇素含量显著高于LD和FD工艺。综合分析,HD和ID工艺加工的香菇品质较好。本研究可为香菇加工技术研究提供理论基础。

Abstract:

Volatile compounds play an important role in the aroma of Lentinula edodes. In this study, headspace solid-phase microextraction (HS-SPME) combined with gas chromatography-mass spectrometry (GC-MS) was utilized to investigate the volatile compounds in Lentinula edodes subjected to different drying methods: freeze drying (FD), low temperature drying (LD), high temperature drying (HD), and infrared drying (ID). A total of 48 volatile compounds were identified across the four processes. Comparative analysis of these compounds revealed higher levels of total volatile compounds, aldehydes, and sulfur compounds in the HD and ID processes compared with the LD and FD processes. Specifically, the contents of dimethyl trisulfide, 1,2,4-trithiopentane, and lenthionine were found to be significantly elevated in the HD and ID processes. These findings suggest that Lentinula edodes processed using HD and ID methods exhibit better quality in terms of aroma compounds. This study can provide a theoretical basis for the research of Lentinula edodes processing technology.

Key words: Lentinula edodes, volatile compounds, drying process
