Physico-chemical and Mechanical Properties of Cornstarch-poly(Lactic Acid) Extrudates as Affected by Ceric Ammonium Nitrate

Abstract

CAN (50 10 m). This corresponded to a decrease in bulk density of the extrudate. Size exclusion chromatography showed that the addition of CAN accelerated the degradation of starch during extrusion. Furthermore, with 0.5 or 1.0% CAN the extrudates expanded poorly and there was no peak at the void volume. PLA molecules have not been degraded by CAN addition.
