Abstract
Acids can be removed from fruit juices by treating the juice with a filter apparatus comprising a pre-coat cake containing a functionally effective amount of weak base resin particulates. The sizes of the particulates are such that substantially all of said particulates range from about -50 to about -100 mesh. The weak base resin is most desirably one wherein the amount of strong base functionalities are less than about 5 percent, based on the total number of strong and weak base functionalities. Juices treated using the pre-coat cake taste sweet and the essential character thereof is not altered.
