摘要: 本文对羊肚菌M0菌株不同发育阶段子实体中的呈味物质进行了分析,以期获得不同发育阶段羊肚菌呈味物质差异。结果表明:M0菌株栽培得到的子实体在不同发育阶段挥发性物质组成和含量不同,主体挥发性香气成分有一定差异,聚类分析表明,B02和B03阶段挥发性成分更为相似;多糖和酚类物质含量随着发育进程而积累;5′-核苷酸含量在生长发育过程中先下降再上升;在生长发育过程中天冬氨酸和谷氨酸的含量没有显著性差异;等鲜浓度值在93.626~269.336 g MSG/100 g之间,且B03的EUC值最高。

Abstract:

The tasting components of the fruiting body of Morchella M0 were studied in different developmental stages.The results showed that the content of volatile tasting components in the fruiting body of strains M0 varied with the development stages.There were some differences in the key volatile aroma components,and cluster analysis showed that the volatile components at B02 and B03 were more similar.Contents of polysaccharides and phenols were accumulated with developmental stages.The content of 5′-nucleotide decreased first and then increased in the developmental stages.As for the content of aspartic acid and glutamic acid,no significant difference was found in the developmental stages.EUC(equivalent umami concentration) of M0 varied from 93.626 to 269.336 g MSG/100 g and expected the highest density on B03.

Key words: Morchella, developmental stage, volatile components, 5′-nucleotide, free amino acid, equivalent umami concentration
