Abstract:
1. Protein micelle aggregates of denatured whey proteins having a molecular size smaller than 1 micron and containing an active agent, with the whey proteins arranged so that hydrophilic parts of the proteins are oriented towards outer parts of the aggregates and hydrophobic parts of the proteins are oriented towards the inner portions of the micelles, wherein the aggregates are obtainable by a method which comprises: adjusting the pH of a demineralised native whey protein solution to a value between 5.8 and 6.0, and heating the solution to a temperature of 80° C. to 98° C. for 10 seconds to 2 hours to obtain negatively charged whey protein micelles; dispersing the negatively charged whey protein micelles and the active agent in a solvent, and evaporating the solvent, wherein the whey protein in the micelles is denatured.
