Abstract
Abstract This invention relates to an improvement in a process for preparing a collagen slurry suitable for the manufacture of edible collagen sausage casing which comprises comminuting a collagen source for forming a collagen pulp, swelling the collagen pulp with an acid for releasing fibrils therefrom, and mixing the swollen collagen pulp with water for forming a slurry; and to the resulting slurry. The invention resides in the discovery that slurries made with a collagen source having a fat content below about 8 percent by weight of the collagen can be improved in terms of casing manufacture by adding and blending a partial fatty acid ester of glycerin to the pulp prior to swelling in an amount effective for selectively reducing the fiber clumps in the slurry.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
112 words
IN A PROCESS FOR PREPARING A SLURRY COMPRISING EDIBLE COLLAGEN AND WATER FOR EXTRUSION INTO AN ARTIFICIAL SAUSAGE CASING BY COMMINUTING A COLLAGE SOURCE FOR FORMING A COLLAGEN PULP; SWELLING SAID COLLAGEN PULP WITH AN EDIBLE ACID FOR RELEASING THE COLLAGEN FIBRILS; AND MIXING SAID COLLAGE PULP IN WATER FOR FORMING A SLURRY; THE IMPROVEMENT FOR REDUCING FIBER CLUMPS IN SAID SLURRY AND IMPROVING THE PRODUCTIVITY OF THE CASING MADE FROM SUCH SLURRY WHICH COMPRISES ADDING TO SAID COLLAGEN PULP PRIOR TO SWELLING AND BLENDING THEREWITH A PARTIAL FATTY ACID ESTER OF GLYCERIN, SAID PARTIAL FATTY ACID ESTER OF GLYCERIN BEING ADDED IN AN AMOUNT EFFECTIVE FOR SELECTIVELY REDUCING SAID FIBER CLUMPS.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
32 words
The process of claim 1 wherein said partial fatty acid ester of glycerin is added to said collagen pulp is a proportion of at least 0.5 percent by weight of the collagen.
Claim 4
Dependent Claim
38 words
The process of claim 2 wherein said partial fatty acid ester of glycerin is added in an amount sufficient to raise the fat and emulsifier content, based on the collagen, to about 6 - 10 percent by weight.
Claim 5
Dependent Claim
26 words
The process of claim 3 wherein said fatty acid portion of said partial fatty acid ester of glycerin has from about 14 - 18 carbon atoms.
Claim 6
Dependent Claim
22 words
The process of claim 4 wherein said partial fatty acid ester of glycerin is a mixed mono and diglyceride of oleic acid.
Claim 7
Dependent Claim
43 words
The process of claim 5 wherein said mixed mono and diglycerides of oleic acid has from about 40 - 50 percent monoglyceride, 35 - 50 percent diglyceride, about 0 - 25 percent triglyceride, and not more than a minor proportion of fatty acid.
Claim 8
Dependent Claim
56 words
In a collagen slurry suited for the manufacture of artificial sausage casings which comprises a dispersion of an acid swollen collagen pulp and water, the improvement which comprises a collagen pulp having been mixed and blended with at least 0.5 percent of a partial fatty acid ester of glycerin prior to swelling with said edible acid.
Claim 9
Dependent Claim

Claim 10
Dependent Claim
43 words

Claim 11
Dependent Claim
26 words
The slurry of claim 8 wherein said fatty acid portion of said partial fatty acid ester of glycerin has from about 14 - 18 carbon atoms.
Claim 12
Dependent Claim
