Keeping Quality and Taste Compounds in the Extracts from Rapid Fermented Anchovy Sauce

As a part of investigation for utilizing anchovy more effectively as a food source, this work was undertaken the changes in keeping quality and taste compounds in the extracts from rapid fermented anchovy sauce during storage at room temperature. Rapid fermented products was made of chopped anchovy, water, koji and soybean protein isolate (20:10:2:1, w/w) thorough hydroxazine for 6 hours at . The liquified anchovy sauce extracts, contained 15% salt(w/w), were stored for 60 days at room temperature. The changes in pH, acidity, amino nitrogen and contents of taste compounds of the products were negligible during storage. The viable cell counts and histamines of the products were less than 30(colony/e extracts), 7.2-21.8(mg/100g extracts) during storage predominant free amino acids showed in the extracts from products were alanine, glutamic acid, histidine, lysine, leucine, valine and the total contents of those free amino acids were 60.4-64.3% of total free amino acids at final stage of storage. The major nucleotides and their related compounds of the products were revealed hypoxanthine, which were 69% over the total nucleotides and their related compounds. Using the omission test, the major taste compounds in the products were revealed free amino acids, nucleotides and their related compounds. The non-volatile organic acids, total creatinine, betaine, and TMAO were seemed to act an auxiliary role in taste of the extracts from rapid fermented anchovy sauce.
