CA 2150571

The present invention provides a whey protein having a phosphorus content reduced to below 0.15 mg per gram of protein, a manufacturing method thereof, a low-phosphorus hydrolysate highly purified and having a low phosphorus content, and a manufacturing method thereof. More particularly, the method for manufacturing the low-phosphorus whey protein of the present invention comprises the steps of adjusting pH of the solution containing the whey protein to below 4, and contacting the solution with a cation exchange resin, sequentially contacting the solution with an anion exchange resin, thereby reducing the phosphorus content to below 0.15 mg per gram of protein, and the highly purified low-phosphorus whey protein hydrolysate of the present invention is available by hydrolyzing the above-mentioned low-phosphorus whey protein with proteases.

L'invention porte sur une protéine de lactosérum avec une teneur en phosphore réduite à moins de 0,15 mg par gramme de protéine, et méthode pour la préparer; hydrolysat à faible teneur en phosphore, hautement purifié, et méthode pour le préparer. Plus spécifiquement, la méthode d'obtention de la protéine de lactosérum à faible teneur en phosphore de l'invention consiste à ajuster à moins de 4 le pH de la solution renfermant la protéine de lactosérum, à mettre en contact la solution avec une résine échangeuse de cations et, successivement, avec une résine échangeuse d'anions, ce qui permet de réduire la teneur en phosphore à moins de 0,15 mg par gramme de protéine; l'hydrolysat de protéine de lactosérum hautement purifié et à faible teneur en phosphore de l'invention est obtenu par hydrolyse de ladite protéine à l'aide de protéases.
