Oil modified cellulosic sausage casings
Abstract
Abstract TUBULAR REGENERATED CELLULOSE FILMS SUITABLE FOR USE AS SAUSAGE CASINGS ARE PREPARED BY INCORPORATING A SINGLE VEGETABLE OR ANIMAL FATTY OIL OR MINERAL OIL IN VISCOSE AND EXTRUDING THE RESULTING MIXTURE INTO CONVENTIONAL COAGULATION AND REGENERATION AND WASH BATHS. THE OIL IS ADDED IN AN AMOUNT RANGING FROM ABOUT 0.1-12% BASED ON THE WEIGHT OF CELLULOSE AND IS EMULSIFIED INTO THE VISCOSE TO PRODUCE OIL DROPLETS IN THE CELLULOSIC CASING HAVING INDIVIDUAL PARTICLE SIZES LESS THAN 0.1 MM. IN DIAMETER. CELLULOSIC SAUSAGE CASINGS HAVING AN OIL CONTENT AND PARTICLE SIZE IN THE RANGE SPECIFIED ARE SOFT AND FLEXIBLE AND MAY BE SHIRRED AT MOISTURE CONTENTS RANGING FROM ABOUT 5% TO ABOUT 20% WITHOUT THE NECESSITY OF ADDING ADDITIONAL MOISTURE TO THE SHIRRED PRODUCT, OR USING SHIRRING LUBRICANT DURING SHIRRING.
