ENCAPSULATION D'EXTRAITS VEGETAUX

摘要

A powdery product is based on one or several plant extracts for animal feed or veterinary medicine. The plant extract(s) are in the form of hydrophobic liquid, adsorbed and/or absorbed in spheroid precipitated silica granules of average size ranging between 90 mum and 500 mum approximately. The spheroid precipitated silica granules containing the absorbed plant extract(s) are coated with a layer of protective coating material. The coating is performed by a fluidized airbed process, enabled by the use of the spheroid precipitated silica granules.
