Optimization of extraction process of biological active substances from pre–treated grape seeds in pulsed electric field

Abstract

The results of the extraction of biologically active substances from grape seeds pre–treated in pulsed electric field. To establish mathematical models has been used Matlab program. Analysis of the experimental data showed the existence of Nonlinear dependencies from and from considerations of modeling accuracy appealed to the spline functions. Nominal mathematical models have been established of the total mass extracted in the functions of number of impulses and the intensity of field for extraction temperatures 25 to 65°C. The components and modeling coefficients were determined with spline functions of extracted total mass of biologically active substances. Keywords: grape seed oil, extraction, biologically active substances, mathematical model.
