摘要

Disclosed is a process for preparing a proteincontaining food wherein the use of a carbon dioxide packaging atmosphere is found to unexpectedly increase the effectiveness of edible aliphatic acids and their edible soluble salts, especially sorbate salts, employed for antimicrobial purposes. In the preferred embodiment, an intermediate moisture pet food containing cooked meat and employing a sorbate salt 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.
