Starches from different vegetal sources (tuber, cereal and legume) were plasticized with an invariant glycerol content and reinforced with cellulose nanocrystals by solution casting method. The influence of both, starch nature and filler amount, in the crystallinity and the extension of plasticization have been analyzed by X-ray diffraction. Thermoplastic starches (TPS) morphologies were obtained by scanning electron microscopy. Mechanical properties and thermal stability were analyzed by dynamomechanical and thermogravimetric analysis. Water absorption evolution was studied as well. A major extension in plasticization (high amylopectin starches) led to matrices with large starch-rich domains, a good thermal stability and resistance to water absorption but low stiffness. The incorporation of cellulose nanoparticles favoured plasticization and increased the rigidity in TPS films, as well as the thermal stability and moisture resistance. The aim of this work was to obtain bio-based thermoplastic starch films for replacing petroleum-derived ones in packaging industry, especially for short-life applications.

UI MeSH Term Description Entries
D007887 Fabaceae The large family of plants characterized by pods. Some are edible and some cause LATHYRISM or FAVISM and other forms of poisoning. Other species yield useful materials like gums from ACACIA and various LECTINS like PHYTOHEMAGGLUTININS from PHASEOLUS. Many of them harbor NITROGEN FIXATION bacteria on their roots. Many but not all species of "beans" belong to this family.
