PepSoyGen is a functional soy protein ingredient from solid-state fermentation technology. Solid-state fermentation is an all-natural, efficient manufacturing process that significantly increases the protein content of PepSoyGen, while eliminating the anti-nutritional factors in soy. Patented strains of Aspergillus oryzae and Bacillus subtilis remain viable in the finished product, providing a valuable source of direct-fed microbials. PepSoyGen is backed by university research and is a consistent, quality protein source.
