C. to create a substantially homogeneous and flowable mixture under extrusion processing conditions. The formulation includes from about 40-90% by weight of grain protein, from about 10-40% by weight plasticizer, and at least about 0.01 by weight of a reducing agent such as sodium bisulfite for cleaving disulfide bonds present in the grain protein. Dental health agents including an acidulent and a chelator are added to promote good dental health. Optional ingredients such as fillers, fiber, lubricant/mold release agents and colorants can also be used. The formulations can be processed in extrusion or injection molding equipment.
