  • Process for treating sweet whey such as to obtain a protein material suitable for hypoallergenic infant formulae
    Patent number: 10912311
    Abstract: The invention concerns a process for the treatment of a sweet whey material containing cGMP (caseinoGlycoMacroPeptide), said process comprising the following steps: —Decationising the sweet whey material so as to obtain sweet whey material having a pH value of 1 to 4.5; —Treating said sweet whey in a fluidized bed reactor comprising a specific volume of an anionic resin, at a temperature between 10 and 18° C., wherein said sweet whey contacts said resin for a sufficient amount of time so that the resin absorbs between 52% and 58% of the cGMP present in the sweet whey; and—Recovering a protein material. Advantageously, the protein material is suitable for hypoallergenic infant formulae.
    Type: Grant
    Filed: February 2, 2016
    Date of Patent: February 9, 2021
    Assignee: Societe des Produits Nestle S.A.

  • Process for treating a sweet whey material containing cGMP and related method for producing a protein material having a targeted tryptophan/threonine ratio
    Patent number: 10561159
    Abstract: Process for the treatment of a sweet whey material (SWM) containing cGMP (caseinoGlycoMacroPeptide), comprising the following steps: Decationising the SWM material so as to obtain a sweet whey SW having a pH value of 1 to 4.5; Treating said SW in a fluidized bed reactor comprising a volume of an anionic resin, at 10 to 18° C., wherein said SW contacts said resin so that the resin absorbs between 0% and 100% of the cGMP present in the SW; and Recovering a protein material; Wherein the treating is such that the resin absorbs 30 to 45 g/L of the cGMP present in the sweet whey.
