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.
Claims16
A raw unprocessed pork-containing product having a denatured outer skin comprising a moisture-containing cellulosic casing uniformly impregnated in its wall with a mixture of an acid and buffer for said acid, which mixture is completely dissolved in the casing moisture and present in sufficient quantity to maintain the casing pH in the range of between about 3.5 and about 4.8 with said mixture comprising the casing sole peeling aid in said wall, said casing being stuffed with raw unprocessed pork-containing mass with the outer skin of said mass thereafter being denatured by contact with the acid-buffer mixture in the casing wall and at least said outer skin of said mass being frozen, said casing being peelable from the denatured pork-containing mass frozen outer skin without further acid treatment or thermal processing.
A raw unprocessed pork-containing product having a denatured outer skin with improved distortion resistance prepared by the steps of:
- a) stuffing raw unprocessed pork-containing mass in a cellulosic food casing having impregnated in the casing wall 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, with said mixture comprising the casing sole peeling acid;
- b) denaturing the raw pork mass outer skin by contact with the acid-buffer mixture in the casing wall;
- c) cooling the raw pork-stuffed casing;
- and
- d) peeling the casing from the cooled raw pork mass denatured outer skin without further said treatment.
