Solid Lipid Microparticles As Carriers of Vaccinium Myrtillus And Schinus Molle Linn Additives for Food Application

Abstract

The diet carried throughout our lives is closely influenced by the presence of free radicals that damage our bodies and develop diseases. Antioxidants are organic molecules capable of preventing cell damage. They are found in food of natural origins, such as blueberries and Aguaribay. A lipid-based transport system is formulated as solid lipid microparticles. This formulation helps counteract the adverse effects of directly applying the ethanolic antioxidant extracts and increases the oil matrix´s useful lifespan. Characterization of the solid lipid microparticle formulations by DSLS, Zeta Potential, Rheology, and TEM confirmed that it protects the compounds encapsulated and stabilizes the active ingredient. Application of the formulation in different commercial oils allowed to establish a reduction in grape oil rancidity in stress conditions. This work indicates that the obtained solid lipid microparticle systems with natural antioxidant compounds can be used as a food additive.
