Abstract: Collagen membranes are formed from porcine rinds (i.e., pig skins) for us in a variety of applications and, most preferably, for wrapping food products, such as hams and the like. First, after removing skins from the porcine, the skins are promptly frozen. In later processing, the rinds are thawed and then enzymatically defatted. Then, a quick alkalinic hydrolyzation is performed on the rinds. Then, an acidic hydrolyzation is performed on the rinds. The rinds are then ground into a gel-like fluid mass. Finally, the fluid mass is extruded, sheeted and dried into a collagen membrane. The collagen membrane produced can be, in preferred embodiments, used for wrapping food products, such as hams.
