Patent number: 6592905Abstract: This invention is directed to a process for producing an immunoglobulin enriched whey protein fraction from whey protein solutions. More particularly, it relates to the production of a whey protein fraction enriched in immunoglobulin, and optionally a whey protein isolate, using a cation exchanger under selected conditions. The selected conditions require overloading the cation exchanger with potentially absorbable protein which causes the exchanger to adsorb preferentially whey proteins other than immunoglobulin. The invention is also directed to the products produced by the process of the invention.Type: GrantFiled: November 16, 1998Date of Patent: July 15, 2003Assignees: Massey University, New Zealand Dairy BoardInventors: John Stephen Ayers, David Francis Elgar, Mark Pritchard

Patent number: 6528622Abstract: A preparative method of isolating a preselected whey protein or group of whey proteins from a solution is provided. The method comprises the following steps: (a) contacting a whey protein solution with the preselected ion exchanger for a time and at a temperature sufficient to enable the preselected whey protein to be adsorbed; wherein the whey protein solution has (1) a protein content in the range of about 5% to about 20% by weight, (2) a pH of a preselected level, which is the level at which the preselected whey protein or group of whey proteins selectively binds to the preselected ion exchanger, and (3) a reduced ionic strength; and (b) recovering either or both of the following: (1) the whey protein component adsorbed in step (a), and (2) the breakthrough whey protein component not adsorbed in step (a).Type: GrantFiled: April 30, 1999Date of Patent: March 4, 2003Assignees: Massey University, New Zealand Dairy BoardInventors: John Stephen Ayers, David Francis Elgar, Mark Pritchard

Patent number: 5024845Abstract: A mutant strain of Schizosaccharomyces #442 (ATCC46954) requiring both glucose and L-malic acid for growth has been produced which is capable of completely utilizing L-malic acid without substantial depletion of glucose. The mutant strain is known as Schizosaccharomyces malidevorans Rodriguez-Thornton #11 (ATCC20771). The yeast is capable of being used to remove L-malic acid from mediums including both L-malic acid and glucose thus making it possible to remove L-malic acid from juices without affecting sweetness, or from grape juices during wine-making conditions without affecting the quantities of glucose available for alcohol fermentation.The invention extends to juice products and wine made using such mutant strains.Type: GrantFiled: December 23, 1987Date of Patent: June 18, 1991Assignee: Massey UniversityInventors: Roy J. Thornton, Susan B. Rodriguez
