FILTER APPARATUS EMPLOYING SMALL SIZED WEAK BASE CONTAINING PARTICLES

摘要

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 axe such that substantially all of said particulates range from 0.25 to 0.125 mm. 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.
