This study investigated the development of fermented meat sauce from pig kidneys (PKs) to promote the use of underutilized livestock byproducts. To this end, we examined the effect of ureter removal and soy sauce yeast (SSY) inoculation on the physicochemical characteristics of the PK sauce mashes (moromis) and the quality of the final products. Ureter removal resulted in a decrease in the L* value of the moromis and an increase in the a* and b* values during the fermentation process. In contrast, SSY inoculation caused the opposite effect in CIE Lab color parameters. A principal component analysis with taste sensor data from the final products after heat treatment and filtration showed that the differences in taste among the four final products were distinguishable. The umami and bitterness tastes were derived from the fermentation of pig kidney sauce and enhanced with SSY inoculation and ureter removal, respectively.
