Stable fat-soluble active principle particles

Abstract

The invention relates to a method for producing fat-soluble active principles, in particular pharmaceutical and/or dietary fat-soluble active principles, in the form of particles. The invention is characterized in that said method comprises the following steps: a) preparation of an oil-in-water emulsion comprising, in weight per cent relative to the total weight of said emulsion: between 8 and 20%, preferably between 10 and 15%, of at least one protein, between 5 and 15%, preferably between 8 and 12%, of at least one sugar, between 0.5 and 3%, preferably between 2 and 3%, of at least one inorganic salt, between 10 and 22%, preferably between 15 and 20%, of at least one fat-soluble active principle in oily form and/or dissolved in an edible oil, and qs for % of water; b) formation of essentially spherical particles by the dispersion of the oil-in-water emulsion obtained at the end of step a) in a fluid; c) addition of at least one protein cross-linking agent to the dispersion obtained at the end of step b); and d) recovery of the active principles in the essentially spherical form.
