To more fully utilize defatted soybeans (DSB) as a food, various defatted soybean ontjoms (DSB ontjoms, fermented DSB with Neurospora intermedia) were prepared. The taste of DSB ontjoms was remarkably improved by adding 10% peanuts or 20% glandless cottonseeds (GLCS) to DSB. In the 20% GLCS-DSB ontjom, gossypol, the toxin of cotton seed, was not detected. The 10% peanut-DSB ontjom and the 20% GLCS-DSB ontjom contained about 50% crude proteins, about 25% soluble proteins, and a limited amount of undigesitible oligosaccharides related to flatulence. These DSB ontjoms to which oilseeds are added are expected to become popular as a digestible protein-rich wholesome and healty food.
