NANOPARTICLE (VERSIONS), COMPOSITION CONTAINING SAID NANOPARTICLE, FOOD PRODUCT INCLUDING SAID COMPOSITION AND METHOD OF PRODUCING SAID NANOPARTICLE (VERSIONS) Russian patent published in 2015 - IPC A23L1/30 A23L1/302 A23L1/305 A61K9/51 A61K8/11 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to nanoparticles for encapsulating biologically active compounds. The nanoparticle contains a casein matrix, a basic amino acid and a metal selected from a group including a divalent metal, a trivalent metal and combinations thereof. Disclosed is a method of producing nanoparticles, which includes preparing an aqueous solution of a casein source and a basic amino acid and adding to the prepared solution an aqueous solution of a metal selected from a group including a divalent metal, a trivalent metal and combinations thereof to obtain a suspension containing formed nanoparticles. Another version of the method of producing nanoparticles includes mixing an aqueous solution of a casein source and a basic amino acid with a solution of a biologically active compound and adding to the obtained mixture an aqueous solution of a metal selected from the group to obtain a suspension containing formed nanoparticles. Nanoparticles obtained using said methods are used in combination with a carrier to prepare food products, as well as in pharmaceutics and cosmetics.

EFFECT: invention enables to obtain nanoparticles with high stability and low polydispersity.
