Process for preparing an emulsion of an active ingredient and particles obtained from this emulsion

Abstract

The invention concerns a method for preparing a double emulsion of a fat-soluble and hydrophobic active ingredient, which comprises the following steps: (a) Providing an aqueous solution of at least one whey protein; (b) Providing an aqueous solution of at least one anionic polysaccharide; (c) Subjecting the whey protein(s) to a denaturation treatment; (d) Hot-preparing an o/w emulsion of the active ingredient in the solution (c), then hot-preparing an (o/w)/w emulsion of the o/w emulsion in the solution (b), or (e) Preparing an w/w emulsion of the solutions (c) and (b), then hot-preparing an o/(w/w) emulsion of the active ingredient in the w/w emulsion. It also concerns the manufacturing of particles of said active ingredient from a thus prepared emulsion, and the obtained particles.
