Agricultural machinery used in the process of denaturation of minced fish proteine

Abstract

The development of the marine industry and processing of raw materials is very important. Many floating marine transport platforms are engaged in processing and preparing raw materials. The paper presents an experimental study of the absorption method of the dependence of the degree of protein denaturation on the absolute value of external hydrostatic pressure, which was used to process minced fish for 5 minutes at a temperature of 295 K. A mathematical model of the process of denaturation of protein molecules in minced fish under the influence of high hydrostatic pressure has been developed. Based on experimental data, the equilibrium constant K = 0.0019439869 of denaturation of protein molecules after 5-minutes action of external hydrostatic pressure at room temperature was determined. Extrapolation of experimental data using a model curve determined the pressure P = 520 MPa, at which the concentration of denatured protein molecules in minced fish for 5 minutes at a temperature of 295 K becomes equal to the concentration of denatured protein molecules in boiled minced fish. These studies are very important for the food and transport industry.
