Abstract
Abstract A ready-to-eat, protein rich, cereal product prepared by cooking a moist, free flowing blend, extruding the cooked blend with a generally uniform cross-section and slicing the extruded blend into thin flakes. A sugar composition, containing those vitamins such as thiamine and lysine that are destroyed by high temperature, is useful as a coating for the extruded product.
