The present work was to study the changes of nonvolatile amines and microorganism in fermentation of anchovy during 12 weeks with addition of various concentration of sodium chloride. Changes of histamine occured significantly during fermentation of anchovy with 10, IS, 20% salt and 10% mixed salts (5.0% NaCl+5.0% KCl). A maximum histamine content was observed in anchovy fermented for 6 weeks while the change of histamine content was not with addition of 20% sodium chloride. Tyramine was found at highest contents in the fermented anchovy of 10% mixed salts and increased markedly in all anchovy fermented for 8 weeks. Cadaverine content was higher in fermented for all fermentation periods than in raw. During fermentation cadaverine contents increased significantly in fermented with 10% mixed salts. In contrast with that, fermented anchovy with 20% sodium chloride had very low those content and high sodium chloride concentration had influenced on amine formation. Although the highest content of putrescine was observed in fermented for 8 weeks, those content was not changed significantly during fermantation. The growth of Microflora, Achromobacter, Aeromonas and Pseudomonas were found in the in itial fermantation and Micrococus, Pediococcus, Lactobacillus and Saccharomyces were found during all fermentation periods.

Nonvolatile amines in fermented ordinary Korean soysauce were separated and quantitated. 1. Tyramine and histamine were detected as nonvolatile amines. Both of them were increased during the fermentation in the soysauce prepared with 22.0% of salt concentration but histamine only was increased in the soysauce with 28.5% salt concentration. Rapid increase of histamine was observed after 80days of fermentation. 2. Two unidentified spots in paper chromatogram which were positive to Sakaguchi reagents were detected. 3. The amounts of tyramine and histamine in fermented ordinary Korean soysauce were much lower than those in Japanese style soysauce.
