Exploitation of by-products from cassava and ahipa starch extraction as filler of thermoplastic corn starch

Abstract

Advances in bio-based composite materials offer potential opportunities for economic revalorization of agroindustrial residues such as starchy tubers peels and bagasse. In this work, cassava and ahipa peels and bagasse are studied as potential fillers of thermoplastic corn starch (TPS) films. It was assessed the effect of studied organic fillers on thermal stability as well as optical, water vapor barrier, and mechanical properties of TPS. In all cases, type (peel or bagasse) and content (0.5 and 1.5 wt %) of the filler had a great impact on the biocomposites properties. Results demonstrated that these fillers modify TPS properties and gives utility to these residues with low economic cost.
