Paper Title:
Effect of Cassava Starch Destructuration to Mechanical Properties of Compostable Blends
  Abstract

Pregelatinized and oxidized cassava starches were proven to be satisfactory to be distributed into poly(lactic acid) and poly(butylene adipate-co-terephthalate) mixture in order to obtain relatively inexpensive compostable material with acceptable properties. Thermoplastic starch from cassava appeared to effectively plasticize the mixture, particularly by pregelatinized starch which underwent complete granular destructuration. The destructuration allowed free hydroxyl groups in starch molecules to bind with free water and resulted in larger free volume which enhanced molecular mobility and, hence, the elongation. However, the destructuration of starch granule accelerated the dissolution of material in water and enhanced water sorption into the blend material.
