Patent number: 4919952Abstract: Food grade protein and dietary fibre concentrates are prepared from wheat millfeed. The process utilizes an efficient alkali extraction to obtain in excess of 75% w/w of the protein present in the millfeed in a solution which is further treated to separate the suspended starch and fat. The clarified liquid containing the protein is passed over a semipermeable membrane during which it is further purified and concentrated. Hydrogen peroxide and heat are introduced to the liquid thereby reducing its color prior to spray drying. The resulting residue from the extraction is dried or further treated with hydrogen peroxide and heat to produce a light colored dietary fibre concentrate.Type: GrantFiled: February 8, 1989Date of Patent: April 24, 1990Assignee: Robin Hood Multifoods Inc.Inventors: Gobind T. Sadaranganey, Wendy Zellen, John Michaelides

Patent number: 4888184Abstract: The invention provides a process of decolorising annatto-containing whey or products produced therefrom, by oxidation with hydrogen peroxide, characterised in that the oxidation is carried out in the presence of a catalytic amount of an active peroxidase, in that the amount of hydrogen peroxide used is sufficient to effect the oxidation of the annatto and in that the time for which the peroxidase is exposed to a deactivating concentration of hydrogen peroxide is insufficient to permanently deactivate the peroxidase. The process is generally applicable to inter alia whey, demineralised whey, reconstituted whey powders, whey protein concentrates and reconstituted whey protein concentrate powders. It may be applied as a batch, semicontinuous or a continuous in line process.Type: GrantFiled: March 19, 1987Date of Patent: December 19, 1989Assignee: Express Foods Group LimitedInventors: Robin C.
