<p>A process for treatment of mechanically removed porcine skins for the production of edible gelatin or of both gelatin and leather, the present invention provides a step-wise method for chemical dehairing and degreasing of the skin, which method offers an environmentally more acceptable procedure for dehairing, degreasing, and ultimately treating the skin to produce gelatin and leather, the quality of the ultimate products being uncommonly high. The dehaired and degreased skin can then be processed for conventional gelatin production or said skin can be mechanically split into a grain layer for leather or gelatin production and a flesh layer for conventional gelatin or leather production.</p> |
