Abstract
Abstract Warm dispersions of collagen that are useful as lubricants and binders when used to make extrusion mixtures or pellets of flours and meals and that form gels that do not liquefy when heated are prepared from washed and neutralized hides by comminuting the hide material, warming the comminuted hide usually to above 40*C. and treating the comminuted hide in a higher shear field.

A PROCESS FOR PREPARING AN IMPROVED SHRIMP AND FISH FEED, COMPRISING THE FOLLOWING STEPS: A. MIXING COLLAGENOUS COMMINUTED HIDE WITH WATER TO OBTAIN A SUSPENSION HAVING A PH OF ABOUT 6.5; B. WARMING THE COMMINUTED HIDE SUSPENSION TO A TEMPERATURE ABOVE 40*C. C. TREATING THE WARM COMMINUTED HIDE SUSPENSION WITH A HIGH SHEAR FIELD UNTIL THE COLLAGENOUS MATERIAL BECOMES A VISCOUS LIQUID HOMOGENATE CONTAINING ABOUT 7.0% SOLIDS AND THAT IS CAPABLE OF FORMING A GEL WHICH WILL NOT MELT UPON PROLONGED BOILING IN WATER; D. COMBINING THE HOMOGENATE OF STEP (C) WITH DRIED SWEET WHEY POWDER AND WATER TO OBTAIN A MIXTURE CONTAINING FROM 3 TO 5% OF THE HOMOGENATE AND ABOUT 70% SOLIDS, E. EXTRUDING THE MIXTURE THROUGH A PLATE HAVING PERFORATIONS RANGING IN DIAMETER FROM ABOUT 1/16 TO ABOUT 1/8 INCHES TO FORM RODS; F. DRYING THE EXTRUDED RODS; AND G. CUTTING THE DRIED RODS INTO PELLET-SIZED LENGTHS OF FEED THAT, UPON BEING PUT IN WATER, SWEEL TO A FIRM GEL AND DO NOT DISINTEGRATE AT TEMPERATURES UP TO 50*C.
