摘要

This paper reveals the amount of flavor compounds produced by yeast depends greatly on concentrations of sodium chloride in the culture media and shoyu. Flavor compounds such as isobutyl alcohol, n-butyl alcohol, isoamyl alcohol, 3-(methylthio)-1-propanol, and 2-phenylethanol, which are derived from amino acids by the actions of shoyu yeast, were decreased with an increase of sodium chloride concentration in the fermented broth. However, the production of 4-hydroxy-2(or 5)-ethyl-5(or 2)-methyl-3(2H)-furanone (HEMF) biosynthesized through the pentose-phosphate cycle reached a maximum at a sodium chloride concentration of 16%. In shoyu brewed in the laboratory scale in various concentrations of sodium chloride, however, not only HEMF but also the alcohols drived from amino acids were produced in the highest quantities at the sodium chloride concentration of 17-18%.
