To develop technologies and processes that will produce value-added food and consumer products from soybean hulls and carbohydrate wastes.
This proposal will establish the economic and technical feasibility of a comprehensive utilization strategy for the production of a number of food and consumer products from soybean hulls and carbohydrate waste streams from soybean processing operations. The ultimate goal of this utilization strategy is to reduce food and agricultural wastes in the life cycle of soybean utilization and provide additional income streams for soybean crushers and farmers by generating high value products such as cat litter, dietary fiber, natural antioxidants, soil amendments, and soy protein isolates from the low value feedstock. We propose to use an acid extraction method to recover soy proteins from soybean hulls (about 9.4% on a DM basis in soybean hulls) and modify the structural carbohydrates in the hulls. The treated hulls and carbohydrate wastes will be dried and milled to achieve the desired particle size distribution. Different fractions of milled hulls and carbohydrates will be used for dietary fiber (fat replacer), cat litter, and soil amendments. These fractions can also be extracted for phytosteryl ferulates and other phenolic antioxidants.
