产果香菌株的初步鉴定及香味成分分析

Preliminary Identification and Aroma Component Analysis in an Aroma-producing Strain

对从安徽砀山果园土壤中分离出的产果香菌进行纯化和菌种形态特征研究,初步鉴定该菌株为地霉属。采用顶空-固相微萃取法(HS-SPME)结合气-质联用技术(GC-MS)分析产生的具有水果香味的物质,结果表明,其主要成分为酯类和醇类,其中最多的是酯类,共32种,占总量的73.84%;醇类物质8种,占12.53%。

An aroma-producing strain was isolated and purified from soil samples collected from Dangshan Anhui province in China and prliminarily identified as Geotrichum based on morphological characteristivs.Hs-S-SPME and GC-MS results indicated that major aroma components were esters and alcohols.The esters exhibited the highest content,which were about 32 species and accounted for 73.84%.In addition,the alcohols were 8 species,which were accounted for 12.53%.
