Abstract
Cellulosic food casing uniformly impregnated with an acid and a buffering agent renders the casing peelable from the denatured frozen outer skin of an encased raw pork-containing product.
Claims18
A method for producing raw unprocessed pork-containing product with a denatured frozen outer skin, comprising the steps of:
- a) providing a cellulosic food casing having pH of at least about 5;
- b) uniformly impregnating the casing wall with an aqueous completely dissolved mixture of an acid and a buffer for said acid in quantity sufficient to reduce the casing pH to the range of between about 3.5 and about 4.8, said mixture comprising the casing sole peeling aid;
- c) shirring the acid-buffer mixture impregnated casing;
- d) deshirring and stuffing raw pork-containing emulsion in said acid-buffer mixture impregnated casing in direct contact with the casing inner surface;
- e) denaturing the outer surface of the raw pork-containing emulsion to form a denatured outer skin by contact with said acid-buffer mixture in the casing wall;
- f) cooling the raw pork-stuffed casing so as to freeze at least the denatured outer skin of the raw pork-containing emulsion;
- and
- g) peeling the casing from the raw pork-containing emulsion frozen and denatured outer skin without further acid treatment.

A method for producing a raw unprocessed pork-containing sausage comprising the steps of:
- a) providing a shirred cellulosic food casing uniformly impregnated with an aqueous completely dissolved mixture of an acid and a buffer for said acid in a quantity sufficient to reduce the casing pH to between 3.5 and 4.8, said acid-buffer mixture comprising the sole peeling aid for said casing;
- b) deshirring and stuffing said casing with a raw pork-containing food product such that the acid-buffer mixture comes into direct contact with said raw pork-containing food product;
- c) denaturing and thereby forming an outer skin on the raw pork-containing food product by direct contact with said acid-buffer mixture;
- d) chilling the stuffed casing;
- and then
- e) peeling the casing from said denatured outer skin of said raw pork-containing food product without further acid treatment.
