  • Patent number: 6444227
    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.

  • Patent number: 6071963
    Abstract: Novel, stable, cold water dispersible preparations of fat-soluble substances contain a microbially produced oil rich in arachidonic acid. These preparations are manufactured by preparing an aqueous emulsion of the microbially produced oil which has been stabilized with an antioxidant and fish gelatin and if desired converting this emulsion into a dry powder. The preparations in accordance with the invention can be used for human nutrition.
