Relationship between microorganisms and volatile components in each fermentation process in the kusaya gravy that plays an important role in the manufacturing of kusaya, a traditional Japanese fermented fish product

The relationship between the microbiota and volatile components of kusaya gravy involved in the manufacturing of kusaya, a traditional Japanese fermented fish product, in the Izu Islands (Niijima and Hachijojima) and the fermentation processes are not clear. In this study, we aimed to investigate the relationship between the microbiota and volatile compounds involved in the manufacturing and management of kusaya gravy.
