The encapsulation of active ingredients in colloidal nanocarriers has interesting potential to be used in controlled release. In particular, it is well know the interest of the different industries, such as pharmaceutical, food and cosmetic in the encapsulation of active principles in different types of nanoparticles (NPs). The goal of this research is focused in the possibility of encapsulation of natural antioxidants in biodegradable polymer nanoparticles. Antioxidants of various types (synthetics or naturals) have been encapsulated in differents biodegradables polymers. In this case, we used natural antioxidants from sweet potato (Ipomoea batata), which were encapsulated in polilactic acid (PLA) nanoparticles, using the emulsification-solvent evaporation technique.
