In the proposed chapter will analyze different starch based nanocomposites employing two types of GRAS filler: natural filler or bactericidal filler. In one case, the filler would be acting as a mechanical reinforcement and introducing a tortuous path to the antioxidant diffusion while on the other, the filler itself has antioxidant property. In the last case, the influence of the filler dispersion into the matrix and its interface in the antioxidant efficiency of the composite will be discussed. Starch based composites with natural antioxidants, as well as with natural (cellulose and clay) and/or bactericidalnanofillerssuch as zinc oxide, titanium dioxide and silver nanoparticles, will be the focus of the discussion.
