Abstract
Abstract A method of stabilizing the cloud of citrus juices is disclosed. The method consists of treating the freshly extracted juice with a pectinase containing polygalacturonase activity. The addition of a proteolytic enzyme enhances the breakdown of calcium pectate by polygalacturonase. Spoilage is prevented by including a chemical sterilant in the preparation of the stabilization treatment.
