Abstract
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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
80 words
In a method for preparing an intermediate-moisture food comprising pasteurized meat and containing a polyhydric alcohol for antimicrobial purposes, 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 polyhydric alcohol 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
80 words
In a method for preparing an intermediate-moisture food comprising pasteurized meat and containing a polyhydric alcohol for antimicrobial purposes, 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 polyhydric alcohol 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
23 words
A method according to claim 1 wherein the polyhydric alcohol is selected from the group consisting of 1,2 propane diol and 1,3-butane diol.
Claim 4
Dependent Claim
52 words
A method according to claim 2 wherein the intermediate-moisture food 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 5
Dependent Claim
22 words
A method according to claim 3 wherein the pet food is a full-feeding, nutritionally balanced dog food containing meat and vegetable protein.
Claim 6
Dependent Claim
12 words
A packaged pet food prepared according to the method of claim 4.
Claim 7
Dependent Claim
87 words
In a method for preparing an intermediate-moisture proteinaceous food comprising non-meat proteinaceous materials as the sole protein source and containing a polyhydric alcohol as an antimicrobial agent, the improvement comprising: packaging said food in a substantially gas impervious material and filling the free space in the package with carbon dioxide, said food containing a level of said polyhydric alcohol 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 8
Dependent Claim
87 words
In a method for preparing an intermediate-moisture proteinaceous food comprising non-meat proteinaceous materials as the sole protein source and containing a polyhydric alcohol as an antimicrobial agent, the improvement comprising: packaging said food in a substantially gas impervious material and filling the free space in the package with carbon dioxide, said food containing a level of said polyhydric alcohol 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 9
Dependent Claim
23 words
A method according to claim 6 wherein the polyhydric alcohol is selected from the group consisting of 1,2 propane diol and 1,3-butane diol.
Claim 10
Dependent Claim
52 words
A method according to claim 7 wherein the intermediate-moisture food 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 11
Dependent Claim
20 words
A method according to claim 8 wherein the pet food is a full-feeding, nutritionally balanced dog food containing vegetable protein.
Claim 12
Dependent Claim
12 words
A packaged pet food prepared according to the method of claim 9.
