Egg yolk granule-curcumin nanocomposite, preparation method and application thereof

Abstract

The invention discloses an egg yolk granule-curcumin nanocomposite, preparation method and application thereof, belonging to the technical field of functional foods. The egg yolk granule-curcumin nanocomposite of the invention includes the following raw materials in parts by mass: 20-40 parts of egg yolk granules, 1-5 parts of curcumin, 0.5-3 parts of food-grade nonionic surfactant, 0.5-3 parts of natural antioxidant, 1-5 parts of emulsification assistant and 5-20 parts of protective agent. By constructing a multi-component system with egg yolk granules as the core, synergized with food-grade nonionic surfactant, lecithin, natural antioxidant and protective agent, the invention effectively overcomes the core problems of curcumin such as poor water solubility, instability and low bioavailability. The composite can form a highly dispersed and stable system of curcumin in the aqueous phase, extend the shelf life, and is conducive to improving its oral bioavailability.
