Patent number: 6001640Abstract: A degumming step in the production of edible oils is disclosed. Vegetable oils from which hydratable phosphatides have preferably been eliminated by a previous aqueous degumming process, are freed from non-hydratable phosphatides by an enzymatic treatment, so that they may be physically refined.

Patent number: 4622300Abstract: A process and reactor are disclosed for the continuous treatment of a turbid liquid with a granular treating agent placed in a fixed bed through which the liquid flows. Preferably, the liquid is whey and the treating agent is lactase immobilized on support particles, and treatment involves hydrolysis of lactose in the whey. During treatment, the flow of whey through the fixed bed is periodically interrupted and a flow of cleansing liquid is passed through the fixed bed countercurrent to the flow of whey. The flow of cleansing liquid is under sufficient hydrostatic pressure to press the fixed bed against moving fragmentation devices to separate and fluidize the support particles into a fluidized bed whereby the support particles containing immobilized lactase are cleansed by removing material deposited thereon from the whey.Type: GrantFiled: March 15, 1984Date of Patent: November 11, 1986Assignee: Rohm GmbH Chemische FabrikInventors: Hans Ottofrickenstein, Hermann Plainer, Bruno Sprossler, Helmut Uhlig
