摘要： The invention concerns a method for isolation of proteins from whey or soy and for modification of the proteins isolated, according to which method: a) whey or soy or a concentrate thereof is brought into contact with a reagent that forms sulfite ions in order to sulfonate the protein, and optionally b) the sulfonated protein is precipitated at an acid pH, and c) the sulfonated protein or the precipitated and soluble sulfonated protein is recovered and optionally processed further.

摘要： The invention relates to a method for isolating proteins from whey, wherein the whey or a concentrate thereof, a reagent which forms sulfite ions, and an oxidative compound are contacted in order to sulfitolyze and oxidize the whey protein, the sulfitolyzed and oxidized whey protein is precipitated out from the whey or concentrate thereof at an acid pH, and the precipitated sulfitolyzed and oxidized whey protein is recovered from the product mixture, and an after-treatment is possibly performed on it. When a food-grade oxidative compound is used as the oxidant and a temperature within the range 25-55 °C is used, the oxidative compound can be caused to react directly with the sulfitolyzed whey protein, and thus the disadvantages associated with the use of a catalyst are eliminated.
