The development of a new salting composition for preserving sheepskin and fur raw materials

Abstract

Hides are raw materials for the manufacture of skins and sheepskins in the conditions of specialized industries. The purpose of this article is to develop a new salting composition for preserving sheepskins using whey. The main areas of research are experimental studies on the selection of preservatives, their dosage and methods of application to sheepskins; studies on the selection of antiseptics, their concentration of solutions and the dose of application to sheepskins; development of a new salting composition for preserving sheepskins; identification of the optimal ratio of the components of the preserving mixture. The article presents the results of the selection of preservatives and antiseptics for the treatment of sheepskins. The organoleptic, physico-chemical and microbiological properties of whey and antiseptics as components of the salting mixture were investigated. The optimal variant of the ratio of the components of the preservative mixture has been identified. It has been established that the use of serum and aldazan antiseptic makes it possible to enhance the effect of canning, reduce the consumption of sodium chloride, and reduce the growth of bacteria during short-term treatment. Generally accepted organoleptic, chemical and microbiological methods were used in the research. The results of the research will be used in the canning of sheepskins during the primary processing of animal skins. The practical significance of the work lies in the use by animal skin processing workshops of the improved technology of preserving sheepskins for their further processing and production into semi-finished leather and finished leather.
