Top note compounds of Chinese traditional bacteria-fermented soybean.
Top note compounds of Chinese traditional bacteria-fermented soybean were analysed by using headspace sampler, GC and GC-MS. Thirty-three note compounds were identified in Chinese traditional bacteria-fermented soybean. Among them, 28 compounds are responsible for the Chinese traditional bacteria-fermented soybean top note. 3-Methylbutanal (6.690%), amyl nitrite (12.976%), 2-methylpropanoic acid (4.014%), 2,3-butanediol (2.171%), 3-methylbutanoic acid (14.273%), 2-methylbutanoic acid (11.866%), benzeneacetaldehyde (1.422%), nonadecane (3.195%), eicosane (5.331%), heneicosane (23.418%) and docosane (5.011%) were all found in concentrations higher than 1.0% (calculated as % peak area of GC analysis using a DB-5 column).
