Mathematical modeling and simulation of the collagen protein hydrolysis process

Abstract

This paper is focused on the mathematical model for alkaline hydrolysis of leather shavings. Leather industry produces annualy a large amount of wastes. For the environment-friendly solution the processing of certain part of wastes arising from the leather industry is reasonable to utilize hydrolysis processes. Collagen protein contained in e.g. leather shavings can be further effectively processed. The description of the hydrolysis process is based on the linearized state model. The mathematical-physical model is built on the mass balance of the input substances and the resulting hydrolysate protein, moreover on an enthalpy balance for the reaction mixture and saturated steam serving in reactor as the heat transfer medium. The simulations of the protein hydrolysis process model are performed in Matlab Simulink and are closely discussed in the paper. © 2016, North Atlantic University Union. All rights reserved.
