NANO-CAPSULES OF FAT-SOLUBLE ACTIVE INGREDIENT, MANUFACTURE AND TYPES OF USE THEREOF Russian patent published in 2021 - IPC A23K40/30 A23K10/30 A23K20/158 A23K20/174 A61K9/51 

FIELD: biotechnology.

SUBSTANCE: proposed are a colloid nano-capsule suspension for administering active ingredient, nano-capsules and micro-particles for administering active ingredient, and use of said nano-capsules and micro-particles in nutrition of animals. Colloid nano-capsule suspension includes nano-capsules. Nano-capsules contain an oil fraction composed of a fat-soluble active ingredient and an ion surface-active agent, a cation or anion hydrophylic polymer surrounding the oil fraction, wherein the charges of the ion surface-active agent and the hydrophylic polymer are opposite and the content of the active ingredient is no less than 5 wt. % relative to the dry mass of the nano-capsules. Micro-particles contain nano-capsules and lactose.

EFFECT: inventions provide increased biological accessibility of the active form of the active ingredient.
