  • Patent number: 4839419
    Abstract: Methods for adsorbing a protein, for example an enzyme, onto an insoluble, solid, macroporous, small-particle support by washing said support with an aqueous solution of the protein containing an electrolyte in an ionic strength of at least 0.15 mole/liter and crosslinking said protein, before, during, or after such adsorption, with a coupling component present in aqueous electrolyte-containing solution.
    Type: Grant

  • Patent number: 4622300
    Abstract: 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.

  • Patent number: 4211799
    Abstract: The method of making citrus juice resistant to flocculation on storage, which method comprises treating naturally turbid citrus juice having a pH below 2.5 with a pectinase of the polygalacturonase-pectinesterase type at a temperature below C. until the alcohol test for pectin is negative, and then decanting the flocculation-resistant supernatant juice after settling.
