Edible collagen casing containing antioxidant

Abstract

Abstract AN EDIBLE SAUSAGE CASING PREPARED FROM HIDE COLLAGEN HAVING IMPROVED ANTIOXIDANT AND APPEARANCE CHARACTERISTICS, AND THE METHOD OF MANUFACTURE THEREOF. ANIMAL HIDES ARE SWOLLEN AND MECHANICALLY UNHAIRED AND SPLIT TO PRODUCE A COLLAGEN CONTAINING CORIUM LAYER. THE CORIUM IS GROUND INTO FINE PARTICLES, FORMED INTO A SLURRY AND SWOLLEN WITH WEAK ACID TO PRODUCE AN EXTRUDABLE COLLAGEN PASTE OR SLURRY HAVING A SOLIDS CONTENT OF ABOUT 2-6%. THE SLURRY IS EXTRUDED THROUGH AN ANNULAR DIE, COAGULATED WITH AMMONIUM SULFATE OR SODIUM SULFATE AND TANNED OR HARDENED IN A BATH CONTAINING ANY SUITABLE NONTOXIC TANNING AGENT SUCH AS ALUMINUM SLATS, FERRIC SALTS, NONTOXIC DIALDEHYDES, ETC. THE TANNED CASING IS WASHED AND FINALLY PLASTICIZED USING AN AQUEOUS SOLUTION OF GLYCERIN OR EQUIVALENT PLASTICIZER, CONTAINING A SMALL AMOUNT OF A MONOGLYCERIDE OR AN ACETYLATED MONOGLYCERIDE, AND AN EDIBLE, NONTOXIC ANTIOXIDANT. THE CASING IS THEN DRIED AND REELED AND EVENTUALLY SHIRRED ON A COMMERCIAL SHIRRING MACHINE FOR DELIVERY TO THE MEAT PACKER IN SHIRRED FORM. THE FINAL TREATMENT OF THE CASING, PRIOR TO DRYING, WITH THE SOLUTION CONTAINING A SMALL AMOUNT OF AN EDIBLE, NONTOXIC ANTIOXIDANT, IS EFFECTIVE TO IMPROVE THE ANTIOXIDANT AND APPEARANCE CHARACTERISTICS OF THE CASING, PARTICULARLY UPON PROLONGED STORAGE.
