Mathematical modelling of a process-economic of protein hydrolyzate production from lupine flour

Abstract

The aim of the present work is to perform the mathematical modelling and computer simulation of the lupine flour hydrolysis technology, which includes the calculations and also the partial comparison of different process variants. Lupine flour is deemed as a source of valuable protein with a substantial content of essential amino acids which has a significant impact on the prevention of various diseases in a human diet. The proposed mathematical model for the production process enables to accomplish the optimal operating conditions while the specific costs for the production of valuable hydrolyzate are minimal. The suggested process-economic mathematical model for the production hydrolysis unit comprises the three main processes for the implementation of the hydrolyzate production, i.e. the chemical reaction and its kinetics, the separation of solids from the reaction mixture by filtration and the thickening of the final product. The results have shown that in most of the simulation cases, the economic optimum occurs and thus the application of the model is valuable for the practical purposes of protein hydrolyzate production. © 2019, World Scientific and Engineering Academy and Society.
