A process is described for the preparation of fat-soluble vitamin active beadlet compositions which exhibit superior stability when exposed to the feed pelleting process. The process includes forming an aqueous emulsion of a fat-soluble vitamin-active material, gelatin, and a sugar converting the emulsion to dry particulate form containing the non-aqueous constituents of the emulsion and heat treating the resulting product to form water insoluble beadlets.

In the process of preparing a fat-soluble vitamin active particulate composition which includes forming an aqueous emulsion of a fat-soluble vitamin-active material selected from the group consisting of vitamin A, D, E, K and derivatives thereof and a protective colloid comprising gelatin and a reducing sugar and further converting said emulsion to a dry particulate form containing the non-aqueous constituents of said emulsion, the improvement which comprises cross-linking the dry particulate form by heat treating said particulate form obtained from said step (2) at from about 90°C. for 2 hours to about 180°C. for less than a minute, whereby such heat treatment insolubilizes the gelatin matrix of the beadlet by a reaction between the carbonyl group of the sugar with the free amino moieties of the gelatin molecule to form water insoluble beadlets.
