The effect of MgCl2 on the kinetics of the Maillard reaction in both aqueous and dehydrated systems
The modification of Maillard reaction kinetics induced by MgCl2 was evaluated in both liquid and dehydrated model systems with special emphasis on the interactions of the salt with water and/or the sugars. In liquid trehalose systems, browning is accelerated by the presence of MgCl2 due to the incre...
