The presence of anti-nutritional factors (ANFs) including non-starch polysaccharides and protease inhibitors in soybean meal (SBM) can negatively affect the physiological status of fish. Especially in the case of carnivorous fish species, such as red drum. To overcome this problem, a solid-state fermentation process has been employed by Nutraferma® as a novel technology for improving the quality of SBM. As a result,  PepSoyGen®, a fermented and functional soy protein ingredient was introduced to the feed industry. The production process of PepSoyGen involves the inoculation of specific microbes (Aspergillus oryzae and Bacillus subtilis) to dehulled, low-temperature sterilized SBM, utilizing solid-state fermentation and enzymatic hydrolysis which reduces the concentration of most ANFs, increases protein content and digestibility, and enriches the final product with beneficial microbes and important metabolites. Overall, these characteristics make PepSoyGen a promising alternative ingredient meriting evaluation in diets of aquaculture species.
