Evaluation of the Stability and Antioxidant Activity of Nanoencapsulated Resveratrol during in Vitro Digestion

Resveratrol was encapsulated in oil-in-water food-grade nanoemulsions of subcellular size, produced by high-pressure homogenization. Physicochemical stability was evaluated under accelerated aging (high temperature and UV light exposure), as well as during simulated gastrointestinal digestion. Antio...

description Resveratrol was encapsulated in oil-in-water food-grade nanoemulsions of subcellular size, produced by high-pressure homogenization. Physicochemical stability was evaluated under accelerated aging (high temperature and UV light exposure), as well as during simulated gastrointestinal digestion. Antioxidant activity was assessed at different stages of digestion by chemical assays and by an improved cellular assay, to measure exclusively the residual activity of resveratrol that penetrated inside Caco-2 cells. Results showed that the nanoemulsions based on soy lecithin/sugar esters and Tween 20/glycerol monooleate were the most physically and chemically stable, in terms of mean droplet size (always
