Abstract
Pig rind is one source of collagen for processing into products, such as sausage casings and films. However, it has a high fat content. The invention produces a defatted collagen paste from a collagen source by cutting the collagen into pieces, pressurising the collagen pieces to squeeze out fat and disintegrating the defatted pieces to form a fibrous paste. The paste can be used to produce a gel, which may be extruded to produce a collagen product.
Claims20
A process for the production of a defatted collagen paste, which comprises;
- providing natural collagen from animal, mammalian, avian or fish skin;
- cutting the collagen into pieces;
- subjecting the collagen pieces to pressure to squeeze out fat and produce defatted pieces;
- and
- disintegrating the defatted pieces to form a fibrous paste.
A process according to any preceding claim, wherein the porcine collagen is derived from young pigs and sows, and comprises 20 to 80% young pig collagen.
A process for the production of an extrudable collagen gel, which comprises swelling the defatted collagen paste produced according to any preceding claim.
