摘要: 采用氨基酸自动分析仪、气相色谱-质谱联用仪对9 份芽孢杆菌发酵大豆样品中的游离氨基酸和挥发性风味成分进行测定,并通过SPSS软件对数据进一步进行因子分析。结果表明:9 株芽孢杆菌对大豆发酵过程游离氨基酸与风味物质的形成均发挥着重要的作用。不同发酵样品氨基酸含量、产香气能力差异较大。通过因子分析,认为酯、醇和醛3 类物质为芽孢杆菌发酵大豆样品中主要香气成分,可为提高发酵豆制品风味品质提供参考。

Abstract: The free amino acid composition and volatile aroma components of fermented soybean made with nine Bacillus strains were analyzed by amino acid analyzer and gas chromatography-mass spectrometry (GC-MS) and the obtained data were analyzed by factor analysis with SPSS software. The results showed that all the Bacillus strains played an essential role in the formation of free amino acids and flavor substances during soybean fermentation. The amino acid contents and aroma-producing abilities of the different fermented samples were different. Through factor analysis, it was concluded that esters, alcohols and aldehydes were the main aroma components in Bacillus fermented soybeans. This study can provide a reference for flavor enhancement of fermented bean products.

Key words: soybean fermentation; Bacillus; free amino acids; flavor
