METHOD FOR SORPTION-CONTACT DEHYDRATION OF FINELY DISPERSED BIOLOGICALLY ACTIVE MATERIALS Russian patent published in 2012 - IPC C12N1/04 A23L3/00

Abstract RU 2454459 C2

FIELD: chemistry.

SUBSTANCE: materials containing biologically active substances in liquid phase are converted to a microdroplet state stabilised with dry finely dispersed hydrophobic separator with nanosized particles, followed by dehydration, with weight ratio of the liquid phase to the sorbent from 1:4 to 1:8.

EFFECT: invention increases shelf life of active substances during storage of dehydrated labile biologically active materials.
