Abstract: A protein-containing composition is provided which is produced by the steps of: coagulating a protein-containing material; emulsifying the protein-containing material; continuously heating the protein-containing material to a predetermined temperature and maintaining that temperature for a period of time sufficient to sterilize the protein-containing material; continuously cooling the protein-containing material; and aseptically packaging the protein containing material. The resulting product is a high quality, highly palatable, and highly digestible protein source which can be shipped without special accommodations regardless of temperature.
