Application of Electric Field Force for the Accumulation of Anthocyanins from Winery Wastewater

The recovery of anthocyanins from winery wastewater constitutes an attractive option for both environmental and commercial valorization, as food colorants nutraceutical ingredients. In this study, the electric field induced ion drift method is proposed a promising technique purification solutions well accumulation anthocyanins. cation anthocyanidin malvidin (C17H15O7+) was selected most representative waste, in order to develop theoretical model. main principle model based on displacement charged anthocyanin ions, under influence vertical flow solution, their side walls conductor. Apparatus inducing described, critical parameters (i.e., final spatial distribution concentration, intensity, surface charge density, potential) were calculated. succeeded reducing concentration by more than 90%, duct widths smaller 1 mm bulk applied potentials φ(0) range 0.2–0.4 V target concentrations equal 1.2 × 10−3 mol/m3.
