ABSTRACT:
Disclosed is a process for preparing a protein-containing food wherein the use of a carbon dioxide packaging atmosphere is found to unexpectantly increase the effectiveness of polyhydric alcohol, especially propylene and butylene glycol, stability agents employed for antimicrobial purposes. In the preferred embodiment, an intermediate moisture pet food, containing cooked meat and employing propylene glycol at a level less than that otherwise effective against mold or bacterial growth, is packaged in an atmosphere of carbon dioxide to provide a pet food stable against mold and bacterial growth.
