Abstract

The aim of this study was to synthesize and characterize the various polymeric adsorbents which are used in the recovery of black carrot anthocyanins by the solid-phase extraction technique. In this context, acrylic and methacrylic monomers were polymerized with the free radical polymerization technique. In resin synthesis, four different crosslinker monomers, different monomer/crosslinker and monomer/diluent ratios were studied. The characterizations of the polymeric adsorbents were designed by size distribution, polymerization yield, scanning electron microscope images and swellability ratio in water and ethanol. In order to determine the best production conditions for polymer adsorbents, they were tested in a model batch system. The T-10-coded adsorbent demonstrated the best performance. The anthocyanins of the black carrot were recovered successfully from carrot juice by using the packed bed adsorption column system which is prepared with T-10. At the end of the study, 3.01 g color components were obtained from 1 L of black carrot juice.
