Extrusion Processing of Starch Film
-
Bing Su
Processing behaviors of starch film using a twin screw extruder were studied; in particular the effect of processing conditions, such as temperature, screw speed, feeding speed, and water content, on the extrusion torque and die pressure were systematically investigated. A specific focus of this work was to investigate the effect of amylose/amylopectin ratio containing in cornstarch on the film processing and performances. It was found that the processibility was decreased as the amylose content increased. Pre-mixing and equilibration improve the processibility of starch films, especially for the high amylose starches. The high amylose starches need higher moisture content and temperature for film extrusion.
