Abstract Sausages, such as frankfurters and bolognas, formed in synthetic casings are more easily peeled by soaking the casings or coating the inner surface, either at the time of manufacture or after stuffing with sausage emulsion, with water-soluble or waterdispersible high molecular weight film forming or substantive carbonyl or sulfonyl containing derivatives of a fluorocarbon. The soluble fluorocarbon derivative is preferably a fluoro or perfluoro ester, amide, ketene, isocyanate, etc. The fluorocarbon derivative is preferably applied to frankfurter sausage casing in the form of a solution or dispersion at the time of manufacture just prior to drying the casing. Fluorocarbon solution or dispersion may also be applied to the soak water for larger casings of the type used for bolognas or may be applied internally to coat such casings at the time of preparation. The use of casings soaked or impregnated with these water-soluble or water-dispersible fluorocarbons facilitates removal of the casing from the smoked and/or cooked sausages at a time when untreated casings could not be peeled from the sausage.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
33 words
A process as defined in claim 1 in which the fluoro-carbon derivative ammonium bis(N-ethyl-2-perfluoroalkyl sulfonamido ethyl) phosphate, poly-(N-ethyl perfluoro octane sulfonamido ethyl acrylate), perfluoro dodecyl ketene(dimer) perfluoro octadecyl isocyanate or perfluoro octadecyl isothiocyanate.
Claim 2
Dependent Claim
18 words
A process as defined in claim 1 in which said solution contains sufficient glycerin to plasticize the casing.
Claim 3
Dependent Claim
44 words
A process as defined in claim 1 in which the casing is a small frankfurter-size cellulosic casing which is impregnated with the treating solution or dispersion to impregnate the fluorocarbon derivative therein to a fluorine content of 0.0001 -0.003 pounds per 1,000 sq. ft.
Claim 4
Dependent Claim
60 words
A process as defined in claim 1 in which the treating solution or dispersion is coated on the inner surface of the casing by introducing a slug of the solution or dispersion through an opening into the interior of the casing so that the casing passing the slug is coated uniformly on its inner surface and the coating dried thereon.
Claim 5
Dependent Claim
17 words
A process as defined in claim 5 in which the sausage casing is a fibrous cellulosic casing.
Claim 6
Dependent Claim
10 words
An artificial sausage casing produced in accordance with claim 1.
Claim 7
Dependent Claim
100 words
In the preparation of sausages by stuffing into an artificial casing the improvement which comprises adding to the casing by soak bath or shower, either before or after stuffing, an aqueous solution or dispersion of a high molecular weight non-toxic water-soluble or water-dispersible film forming or substantive aliphatic fluorocarbon carbonyl or sulfonyl containing derivative selected from the group consisting of a perfluoro ester, amide, ketene, isocyanate or isothiocyanate to introduce into the casing the fluorocarbon derivative at a fluorine content of 0.0001 -0.09 pounds per 1,000 sq. ft. of casing, to improve the peelability of the casing from the sausage.
