This research work aimed extraction and characterization of arrowroot starch. Besides, the effects of different concentrations of starch (2.59–5.41%, mass/mass) and concentrations of glycerol (9.95–24.08%, mass versus starch mass) on films properties were evaluated by a rotational central composite 2² experimental design. Arrowroot starch showed high amylose content (35%). Low values were found for the swelling power and solubility index. The X-ray diffraction showed “C” type crystalline structures, while thermogram showed Tg around of 118 and 120 °C. The thermogravimetric analysis showed that 40% of mass loss of starch occurred between 330 and 410 °C. The films were homogeneous, transparent and manageable. Starch and glycerol concentrations played a significant role in thickness and solubility in water of films, but was not significant for water vapor permeability and tensile strength. Therefore, arrowroot is a very promising starch source for application in films.

这项研究工作旨在提取和表征竹芋淀粉。此外，通过旋转中心复合材料评估了不同浓度的淀粉（2.59–5.41％，质量/质量）和甘油浓度（9.95–24.08％，质量与淀粉质量）对薄膜性能的影响2 ²实验设计。竹芋淀粉显示出高直链淀粉含量（35％）。发现溶胀度和溶解度指数低。X射线衍射显示“ C”型晶体结构，而热谱图显示Tg在118和120°C附近。热重分析表明，在330至410°C之间发生了40％的淀粉质量损失。这些膜是均质的，透明的并且易于处理。淀粉和甘油的浓度对薄膜的厚度和在水中的溶解度起着重要的作用，但对水蒸气的渗透性和抗张强度影响不大。因此，葛粉是用于膜的非常有希望的淀粉来源。
