Abstract Lutein is a carotenoid presenting known anti-inflammatory and antioxidant properties. Lutein-rich diets have been associated with neurological improvement as well as reduction of the risk of vision loss due to Age-Related Macular Degeneration (AMD). Micro and nanoencapsulation have demonstrated to be effective techniques in protecting lutein against degradation and also in improving its bioavailability. However, actual lutein concentration inside the capsules and encapsulation efficienc...

Abstract Lutein is a xanthophyll carotenoid widely known by its biological properties and low toxicity. When located in the brain, lutein may inhibit damage mechanisms, acting in neural cells maintenance. However, this carotenoid is very sensitive to external agents such as heat, light, pH and oxidation, besides presenting low absorption in gastrointestinal tract due its low solubility in water. Encapsulation procedures have shown promising results to increase lutein stability and bioavailabilit...
