Abstract
Abstract This invention relates to an artificial sausage casing of regenerated cellulose having a coating composition applied over the internal surface thereof which exhibits excellent meat release from sausages processed therein under high speed mechanical peeling and has improved resistance to strand breakage and pinholing during shirring and meat processing, the coating being an admixture of a water-soluble cellulose ether, a partial fatty acid ester of sorbitan or mannitan and a water-soluble polyalkylene glycol ether having the formula RO(-C2H4O)n-H wherein R represents long chain alkyl radicals having 8 to 16 carbon atoms and n is an integer from 4 to 40.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
97 words
A process for preparing an artificial sausage casing of regenerated cellulose having improved meat release properties and resistance to breakage which comprises: applying to the internal surface of the casing a substantially homogeneous aqueous coating composition containing a water-soluble cellulose ether, a partial fatty acid ester of a polyhydric alcohol selected from the group consisting of sorbitan and mannitan, and a water-soluble polyalkylene glycol ether of the formula R(--OC 2 H 4 O) n --H wherein R represents long chain alkyl radicals having 8 to 16 carbon atoms and n is an integer from 4 to 40.
Claim 2
Dependent Claim
97 words
A process for preparing an artificial sausage casing of regenerated cellulose having improved meat release properties and resistance to breakage which comprises: applying to the internal surface of the casing a substantially homogeneous aqueous coating composition containing a water-soluble cellulose ether, a partial fatty acid ester of a polyhydric alcohol selected from the group consisting of sorbitan and mannitan, and a water-soluble polyalkylene glycol ether of the formula R(--OC 2 H 4 O) n --H wherein R represents long chain alkyl radicals having 8 to 16 carbon atoms and n is an integer from 4 to 40.
Claim 3
Dependent Claim
54 words
The process of claim 1 wherein the coating composition applied to the casing contains about 0.5 to about 2.5% by weight of the cellulose ether, about 0.5 to about 5% by weight of the partial fatty acid ester and about 0.025 to about 0.20% by weight of the polyalkylene glycol, the balance being water.
Claim 4
Dependent Claim
12 words
The process of claim 1 wherein said cellulose ether is carboxymethyl cellulose.
Claim 5
Dependent Claim
23 words
The process of claim 1 wherein said partial fatty acid ester of a polyhydric alcohol is a partial fatty acid ester of sorbitan.
Claim 6
Dependent Claim
16 words

Claim 8
Dependent Claim
85 words
An artificial sausage casing of regenerated cellulose having a coating applied over the internal surface of the casing, said coating being a substantially homogeneous admixture of a water-soluble cellulose ether, a partial fatty acid ester of a polyhydric alcohol selected from the group consisting of sorbitan and mannitan, and a polyalkylene glycol ether having the formula RO(--C 2 H 4 O) n H wherein R represents long chain alkyl radicals having 8 to 16 carbon atoms and n is an integer from 4 to 40.
Claim 9
Dependent Claim
85 words
An artificial sausage casing of regenerated cellulose having a coating applied over the internal surface of the casing, said coating being a substantially homogeneous admixture of a water-soluble cellulose ether, a partial fatty acid ester of a polyhydric alcohol selected from the group consisting of sorbitan and mannitan, and a polyalkylene glycol ether having the formula RO(--C 2 H 4 O) n H wherein R represents long chain alkyl radicals having 8 to 16 carbon atoms and n is an integer from 4 to 40.

Claim 11
Dependent Claim
14 words
The artificial sausage casing of claim 7 wherein said cellulose ether is carboxymethyl cellulose.
Claim 12
Dependent Claim
25 words
The artificial sausage casing of claim 7 wherein said partial fatty acid ester of a polyhydric alcohol is a partial fatty acid ester of sorbitan.
Claim 13
Dependent Claim
