Process for the production of beadlets

A process for the production of cross-linked beadlets containing one or more active ingredients selected from the group of a fat-soluble vitamin active material, a carotenoid and a polyunsaturated fatty acid, which comprises the steps of:

• forming an emulsion containing the active ingredients, an emulsifier and a reducing sugar, converting the emulsion to droplets,
• coating the droplets with finely dispersed powder,
• separating a dry particulate form from the remaining finely dispersed powder, and heat treating said particulate form, wherein
• the dry particulate form is heat treated at a temperature in the range of from 90° C. to 140° C. for a time period of from 30 seconds to 30 minutes or from 1 minute to 10 minutes or from 3 minutes to 7 minutes in such a way that the final beadlet forms have a core and a surface region, wherein the core region contains, in a high concentration, the active-ingredients and the surface region contains less than 10% of the total active ingredient content.
