Abstract
The invention relates to a process for preparing beadlets containing fat soluble substances in a gelatin matrix which comprises crosslinking the gelatin by radiation or enzymatically. Specifically, the invention relates to a process for preparing beadlets containing fat soluble substances having the steps of: (1) forming an aqueous emulsion of a fat soluble substance, a gelatin, a reducing agent; (2) converting the emulsion into a dry powder; and (3) crosslinking the gelatin matrix in the coated particles by exposing the coated particles to radiation or, in the case of a crosslinking enzyme being present, by incubating the coated particles.
