METHOD OF PRODUCTION OF THE MICROCAPSULES Russian patent published in 2008 - IPC B01J13/06 B01J13/20 

FIELD: industrial biotechnology; methods of production of the microcapsules.

SUBSTANCE: the invention is pertaining to the industrial biotechnology and is intended for production of the micro-capsulated biopreparations of the natural compounds. The purpose of the invention is development of the effective method of production of the microcapsules of the liquid-phase natural substances. The method is exercised by the emulsification of the encapsulated substance in the polymer solution and sedimentation of the polymer on the surface of the emulsion drips. The sedimentation(is conducted three times at the temperature of 75-80°C during 5-10 minutes at the continuous stirring with the subsequent treatment with the acetone In the capacity of the polymer solution use 1-2.5 % solution of methyl cellulose with the content of the metoxyl groups from 27.5 up to 32 %. In the capacity of the emulsifier use the rape oil in amount of 7.5-40 mass % from the amount of the polymer solution.

EFFECT: the invention ensures development of the effective method of production of the microcapsules of the liquid-phase natural substances.
