Abstract

The present invention relates to a method for obtaining nanostructures, specifically nanoemulsions and nanocapsules of carotenoids such as curcumin and astaxanthin. This method—using particular concentrations of the ingredients forming the nanostructures—allows high association efficiencies of the active ingredient in the nanostructures containing these ingredients and protection of these nanostructures from environmental factors such as oxidation and light. The invention also relates to the nanoemulsions and nanocapsules of curcumin and astaxanthin for use in the food, pharmaceutical and cosmetics industries, among others.

Dependent claims

A method to obtain nanostructures with carotenoids, WHEREIN said method comprises the following steps:

a) mixing a carotenoid compound with an anionic surfactant, a water miscible organic solvent and a liquid oil, in a mass ratio of 1:5-70:10-1000:30-250, respectively;
b) adding water to the mixture described in step (a) in a ratio of 1:1-100, respectively;
and
c) removing the organic solvent to obtain a nanoemulsion.
