对金针菇和茶树菇中非挥发性成分进行研究,对2种食用菌非挥发性成分甘露醇、核苷酸、游离氨基酸进行对比分析。结果表明:金针菇中甘露醇含量明显高于茶树菇;茶树菇中呈鲜味的核苷酸及氨基酸含量明显高于金针菇。金针菇和茶树菇在非挥发性成分上存在较大差别,茶树菇中非挥发性成分较金针菇丰富;非挥发性成分的差异是引起金针菇和茶树菇感官差别的主要原因。

The non-volatile compounds of Flammulina velutiper and Agrocybe chaxinggu were studied.The comparison among mannitol,nucleotide and amino acid were analyzed.Mannitol content in Flammulina velutiper was more than that of in Agrocybe chaxinggu,while the contents of nucleotide and amino acid in Flammulina velutiper were less than in Agrocybe chaxinggu.The results showed that there were significant differences in non-volatile compounds between the two types of mushroom.The non-volatile components of Agrocybe chaxinggu were richer than Flammulina velutiper.The differences between the non-volatile components in the two types were mainly responsible for the sensory differences between Flammulina velutiper and Agrocybe chaxinggu.
