ABSTRACT
This review addresses the biovalorization of the okara, a water-soluble soy extract industry byproduct. This material is highly susceptible to decay due to its high water content and appreciable levels of nutrients (proteins, dietary fibers, and isoflavones). Details on the extraction processes which are applied for the isolation of the key compounds are emphasized, as well as the main characteristics of these products. The development of new and safer processes is required to achieve the overall reuse of the okara components, avoiding the generation of new agro-industrial wastes, and applying the isolated nutrients to products intended for humans.
