Multi-object optimization with combination criteria applied to extraction of the high colour degree Anthocyanin

Abstract

This paper is going to present a study of the Multi-Object Optimization Method with combination criteria S and R.  The mathematical models on the basic of the experimental research showed the effect of technical factors (temperature, time and HCl concentration) to the extraction of anthocyanin pigment. By employing the multi-object optimization method with combination criterion R, the best technological parameters on the anthocyanin extract process are defined: Temperatute - 51oC, HCl concentration - 0.41N, and extract time - 56 minutes. In this extract condition, we obtained the high concentration of anthocyanins - 1.203% and the higt colour degree - 3.20 .
