Abstract
Abstract Disclosed is a process for preparing a protein-containing 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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
91 words
In a method for preparing an intermediate-moisture food comprising pasteurized meat and containing an antimicrobial agent selected from the group of linear aliphatic acids, their edible salts, and combinations thereof, the improvement comprising: packaging said food in a substantially gas impervious packaging material, and filling the free space in the package with carbon dioxide, said food containing a level of said antimicrobial agent which is ineffective in the absence of the carbon dioxide to prevent microbial growth, but effective to prevent microbial growth when the food is packaged in carbon dioxide.
Claim 2
Dependent Claim
91 words
In a method for preparing an intermediate-moisture food comprising pasteurized meat and containing an antimicrobial agent selected from the group of linear aliphatic acids, their edible salts, and combinations thereof, the improvement comprising: packaging said food in a substantially gas impervious packaging material, and filling the free space in the package with carbon dioxide, said food containing a level of said antimicrobial agent which is ineffective in the absence of the carbon dioxide to prevent microbial growth, but effective to prevent microbial growth when the food is packaged in carbon dioxide.
Claim 3
Dependent Claim
24 words
A method according to claim 1 wherein the linear aliphatic acid is selected from the group consisting of sorbic, caproic, caprylic, propionic and combinations.
Claim 4
Dependent Claim
15 words
A method according to claim 2 wherein the microbial growth referred to is mold growth.
Claim 5
Dependent Claim
15 words
A method according to claim 2 wherein the microbial growth referred to is bacterial growth.
Claim 6
Dependent Claim
52 words
A method according to claim 3 wherein the intermediate-moisture product is a pet food and has a moisture content of from about 15 to about 50% by weight of the total composition, an A w of from about 0.5 to about 0.93 and a pH of from about 3.5 to about 8.0.
Claim 7
Dependent Claim
21 words
A method according to claim 5 wherein the pet food is a full-feeding, nutritionally-balanced dog food containing meat and vegetable protein.
Claim 8
Dependent Claim
14 words
A method according to claim 6 wherein the linear aliphatic acid comprises sorbic acid.
Claim 9
Dependent Claim
13 words
A packaged pet food product prepared according to the method of claim 5.
Claim 10
Dependent Claim
98 words
In a method for preparing an intermediate-moisture proteinaceous food containing non-meat proteinaceous materials as the sole protein source and containing an antimicrobial agent selected from the group of linear aliphatic acids, their edible salts, and combinations thereof, the improvement comprising: packaging said food in a substantially gas impervious packaging material, and filling the free space in the package with carbon dioxide, said food containing a level of said antimicrobial agent which is ineffective in the absence of the carbon dioxide to prevent microbial growth, but effective to prevent microbial growth when the food is packaged in carbon dioxide.
Claim 11
Dependent Claim
98 words
In a method for preparing an intermediate-moisture proteinaceous food containing non-meat proteinaceous materials as the sole protein source and containing an antimicrobial agent selected from the group of linear aliphatic acids, their edible salts, and combinations thereof, the improvement comprising: packaging said food in a substantially gas impervious packaging material, and filling the free space in the package with carbon dioxide, said food containing a level of said antimicrobial agent which is ineffective in the absence of the carbon dioxide to prevent microbial growth, but effective to prevent microbial growth when the food is packaged in carbon dioxide.
Claim 12
Dependent Claim
13 words
A method according to claim 9 wherein the food is a pet food.
