Abstract
Abstract A method for producing expanded, textured protein products which comprises mixing oleaginous seed materials and an aqueous liquid in a ratio of between 1:0.2 and 1:4 to form a mixture having a pH of between about 4 and 7; generating heat internally in the mixture by means of radiant energy (e.g. infrared, microwave, induction ovens) to expand the mixture at substantially atmospheric pressure to form an expanded product, setting the expanded product to form an expanded substantially waterinsoluble irreversible cross-linked structure; and subsequently cooling the expanded product.
