| Outline of Final Research Achievements |
Recently, a new type fish sauce was developed. This fish sauce was produced from the liver which was the waste in the processing of abalone. However, due to its distinctive odor, there is a limit to its marketability to consumers. Therefore, the aims of this research were to clarify the aroma characteristics of abalone liver soy sauce (ALSS) and to search for a method to improve the flavor of ALSS by fermentation using yeast or koji. According to the results of analysis, the sweaty and cheese-like odor in ALSS were stronger than that in other commercial fish sauce. The methods of fermentation by koji or yeast were effective both for improving the flavor of ALSS. In the sample of fermented ALSS with koji, the intensity of cheese-like and roasty odor was stronger, while the distinctive unpleasant odor was decreased. In addition, the sample which fermented by yeast had all of the aroma characteristics of fermented ALSS by koji described above, and also had a strong sweet aroma.
