ENCAPSULATING PLANT EXTRACTS ADSORBED AND/OR ABSORBED IN PRECIPITATED SILICA

摘要

The invention concerns a powdery product based on one or several plant extracts for animal feed or veterinary medicine. In said product, the plant extract(s) are in the form of hydrophobic liquid (1), adsorbed and/or absorbed in spheroid precipitated silica granules (2) of average size ranging between 90 µm and 500 µm approximately. The spheroid precipitated silica granules (2) containing the absorbed plant extract(s) (1) are coated with a layer of protective coating material (3). The coating is performed by a fluidized airbed process, enabled by the use of the spheroid precipitated silica granules (2).
