Abstract

The invention relates to a method for preparing a concentrate of denatured whey protein aggregate preferably having a mean aggregate size (median) of between 1 and 4 &mgr;m. Said method consists of the following steps: a) an aqueous solution enriched to a maximum protein content of 4% by weight, containing whey protein and having a pH of between 5.0 and 7.0 is thermally denatured to [≦80%] ≦90%, in relation to the protein content, under substantially non-shear conditions at a temperature of between 75 and 150° C. and by means of a holding period; and b) the resulting product is concentrated, preferably to a denatured whey protein concentration of between 5 and 20%.
