摘要:

用顶空固相微萃取法(HS-SPME)提取传统发酵豆酱中的风味物质,通过气质联用(GC-MS)结合气相-嗅闻法(GC-O)分析豆酱的风味成分,确定豆酱中的主要呈香物质以及各物质对风味的贡献度。实验得出26种挥发性物质与风味的对应关系,其中HEMF、酯类、2,3-丁二醇、乙酸、苯甲醛、苯乙醛、2,6-二甲基吡嗪对豆酱的风味贡献较大。

Abstract:

In order to confirm the aromatic components and their contributions to flavor of traditional soybean paste, volatile flavor compounds in traditional soybean paste were xtracted by headspace solid phase micro- extraction (HS-SPME), and analyzed by gas chromatography-mass spectroscopy (GC-MS) combined with GC-olfactory method. Totally 26 volatile compounds were identified from GC elution to contribute the flavor of soybean paste. Esters, 4-hydroxy-2(or 5)-ethyl-5(or 2)-methyl-3(2H)-furanone (HEMF), 2,3-butanediol, acetic acid, benzaldehyde, benzene acetaldehyde and 2,6-dimethyl-pyrazine were the major flavor-active compounds in soybean paste.

Key words: soybean paste, GC-olfactometry, GC-MS, volatile compound
