Abstract:
1. A process for deacidifying a citrus juice stream with ion exchange resin, comprising: (a) providing an ion exchange resin, said resin either being theretofore unused or having been regenerated with a basic composition thereby removing anions from the resin and reestablishing a fresh binding affinity of the resin for acidic ions; (b) conditioning the resin by contacting the resin with an aqueous food-grade acid preconditioning composition, thereby decreasing the binding affinity of the resin for acidic ions and providing preconditioned ion exchange resin; and (c) flowing citrus juice through said pre-conditioned ion exchange resin to provide a deacidified flow of citrus juice while avoiding raising the pH of the juice to above that of an acid food pH for said citrus juice.
