The control of Maillard reaction in white grape molasses by the method of reducing reactant concentration

Abstract The aim of this study was to investigate the impact of removing sugar and/or amino groups by applying one ion exchange (Dowex 50Wx8) and two adsorbent (Activated Carbon and Amberlite XAD-16) resins to grape juice in the control of Maillard reaction. Grape juices, a control sample and separately applied with each resin, were concentrated up to 50, 60 and 70 °Bx and stored at three temperatures (50, 65 and 75 °C) for 10 days. HMF accumulation was lower in the grape juices which were treated with Amberlite or activated carbon throughout the boiling. Rate constant, activation energy and...
