Abstract :In this study, effect of the activated carbon, Amberlite® XAD-16 adsorbent resins and Dowex® 50Wx8-100 ion exchange resin applications on the mineral content of grape juice and molasses was investigated. Grape juices applied and unapplied resins were concentrated to 50, 60 and 70o Brix by conventional method. Macro insert ignore into journalissuearticles values(Ca, Na, P, S, K and Mg); and micro insert ignore into journalissuearticles values(B, Cr, Cu, Fe, Mn, Ni, Pb and Zn); element analyses were performed to the grape juices and pekmez insert ignore into journalissuearticles values(molasses); by ICP-AES method. The mineral content of grape juice was not affected by the activated carbon, but calcium insert ignore into journalissuearticles values(Ca); content of the grape juice applied Dowex® 50Wx8-100, and sulphur insert ignore into journalissuearticles values(S); content of grape juice applied Amberlite® XAD-16 were decreased 47.21% and 6.11%, respectively. All macro minerals analyzed in the grape molasses produced without applying resin were decreased by concentration process. On the other hand, Ca, S and Mg content by applying activated carbon, and only Mg content by applying Dowex® 50Wx8-100 were decreased in the grape molasses.
