Structural Transformations of Collagen Containing Raw Materials under Alkaline Treatment

Abstract

Abstract. In the research of the rawhide structural transformations in chemical-and-colloidal processes under the action of alkaline dispersion, collagen of the dermis gets free of preservative agents and globular proteins. The conditions of rawhide alkaline treatment, under which the structure of a semi-finished product preserving amino-acid composition of collagen of the dermis is formed, have been outlined. A comparative analysis of the developed technologies of a leather semi-finished product formation from cattle rawhide has been carried out.
