STABLE DRY POWDER COMPOSITION CONTAINING BIOLOGICALLY ACTIVE MICROORGANISMS AND/OR BIOLOGICALLY ACTIVE MATERIALS AND METHOD OF ITS PRODUCTION Russian patent published in 2015 - IPC C12N11/02 C12N1/04 A23K1/16 

FIELD: process engineering.

SUBSTANCE: set of inventions relates to stable dry composition and method of its production. Composition comprises live microorganism or material, two stabilizing agents, sodium alginate and inulin, and two protective agents, disaccharide and protein digest. Note here that said live microorganism or material is enclosed in amorphous glassy matrix. Composition is used for feeding of animals provided that it is not a herbicide. Claimed process comprises the steps that follow. First, components are combined in water solvent to cool the obtained mix to temperature above its freezing point. Cooled mix is subjected to primary drying in vacuum at temperature above its freezing point and to secondary drying at 20°C or higher for time interval sufficient for decreased in water activity Aw in said mix to 0.3 or lower. Invention discloses also the composition for production of stable dry composition with viscosity of about 10 Pa·s to about 450 Pa·s.

EFFECT: stable properties at high temperature and humidity.
