Interpretive Summary: This patent describes a novel technology in which clay-based sequestrants are used to sequester aflatoxin from contaminated peanut meal during protein extractions to generate mycotoxin reduced (below FDA level tolerated for human foods) protein/peptide concentrates. Commercially available proteases are used to improve protein extraction efficiencies and increase antioxidant capacities of the extracted proteins/peptides. A value added feed grade material is simultaneously prepared in this process. This technology could be applied to other mycotoxin contaminated biomaterials.

Technical Abstract: Peanut oil is valued worldwide, primarily as a cooking medium and food ingredient. This chapter provides timely summaries and discussions on the latest compositional, physical and nutritional data for peanut oil.
