摘要:

通过采集传统发酵过程中的永川豆豉样本,采用固相微萃取和气相色谱-质谱联用技术对其挥发性风味物质在发酵过程中的变化进行测定。发现永川毛霉型豆豉的主体风味以酱香为主,成品豆豉中含有化合物95 个,其中酯类化合物31 种、烃类化合物20 种、酮类化合物8 种、羧酸类化合物6 种、醇类化合物5 种、醛类化合物 5 种、酚类化合物5 种、苯类化合物3 种和其他类化合物 11 种。同时,风味物质以乙酸乙酯、苯甲酸乙酯、邻苯二甲酸二丁酯、环戊酮、苯乙酮、3-辛酮、苯乙醇、苯甲醛、苯乙醛等含量高阈值低的挥发性物质为主混合生成的独特酱香。芳香族氨基酸降解所产生苯乙醛、苯乙醇、苯乙酮对豆豉风味形成贡献较大。

Abstract:

In this study, Yongchuan Douchi samples during different stages of fermentation were collected and the changes
in their volatile flavor compounds were determined by solid-phase microextraction and GC-MS. It was found that its main
flavor was sauce-flavor. The final Douchi contained 95 compounds, including 31 esters, 20 hydrocarbons, 8 ketones, 6
carboxylic acids, 5 alcohols, 5 aldehydes, 5 phenols, 3 benzenes and 11 other compounds. Meanwhile, the particular sauce
flavor was produced by high contents oflow threshold compounds such as ethyl acetate, ethyl benzoate, di-butyl phthalate
(DBP), cyclopentanone, acetylbenzene, 3-octanone, phenethanol, benzaldehyde, and phenylacetaldehyde. Phenylacetaldehyde,
phenethanol and acetylbenzene generated from aromatic amino acids had greater contribution to the flavor.

Key words: Yongchuan Douchi, sauce-flavor, flavor substance, mechanism
