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.
