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. Method for producing a protein material from a SWM cGMP, said protein material having a targeted tryptophan/threonine (Trp/Thr) ratio, comprising the following steps: —Implementing the treating process twice, wherein the resins absorbs P1 of the cGMP, obtaining a first protein material having Trp/Thr1 and wherein the resins absorbs a percentage P2 of the cGMP, obtaining a second protein material having Trp/Thr2; —Drafting the linear calibration curve in a graph (cGMP %; Trp/Thr) by positioning (Trp/Thr1; P1) and (Trp/Thr2; P2) and drawing a line through these two plots; —Determining the specific ratio of cGMP pr…
