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 μm. 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%.
Claims12
A process for producing a concentrate of denatured whey protein aggregates, the process essentially consisting of the steps that
- a) an aqueous whey protein solution having a whey protein content of at most 3% by weight is heat-denatured by hot-holding at a temperature in the range from 75 to 150° C., at a pH in the range from 5.0 to 7.0 under essentially non-shearing conditions in such a manner that ≦90% of the whey protein are heat-denatured to form whey protein aggregates having a mean aggregate size (median) in the range from 1 to 4 μm, and that
- b) a concentration step is then carried out.
