Abstract

Volatile flavor compounds of cheonggukjang and doenjang, which are the most representative Korean soybean fermented foods, were compiled throughout literature review. Total of 225 and 404 volatile flavor compounds were found in cheonggukjang and doenjang, respectively. The most characteristic volatile flavor compounds in cheonggukjang are thought to be pyrazine compounds. In addition, acids, such as 2-methyl propanoic acid, butanoic acid, 2-methyl butanoic acid, and 3-methyl butanoic acid, contribute to aroma characteristics of cheonggukjang. On the other hand, ester compounds are the most predominant volatile flavor compounds in doenjang. Ninety six ester compounds were detected in doenjang while 22 ester compounds were identified in cheonggukjang. Pyrazine compounds and acids also play an important role in the flavor of doenjang. Compilation of volatile flavor compounds from cheonggukjang and doenjang will provide basic information to food industry to understand and improve aroma characteristics of cheonggukjang and doenjang.
