Renewable natural polymers such as plant proteins or starch usually experience difficulties in thermal processing, and a large amount of plasticizers is normally used which decreases the strength of the materials especially under wet conditions. The back pressure equal channel angular consolidation (BP-ECAC) method provides a methodology to produce plastic natural polymer materials at low temperature without using additional plasticizers. Wheat gluten and starch powders were successfully processed into plastic materials without using additional plasticizers at low temperatures by the technology. The materials displayed improved mechanical properties and the effect of processing temperature was also examined in this report.
