A protein system for food products containing a moisture source is provided comprising a combination of intact proteins, casein, and partially hydrolyzed dairy protein and partially hydrolyzed legume protein in a total amount effective to reduce mixing time and/or shear requirements, and reduce firmness development during processing and storage of the food products to increase shelf life. The reduced firmness is achieved without embittering the food product by using a protein blend delivering a unique balance of partially hydrolyzed and intact proteins, and casein. Methods of making the food products with the protein blends are also covered.
