Abstract The objective of the study was to determine the effects of molecular sizes of amylose (AM) and starch granules on the mechanical properties of thermoplastic starch (TPS) blend films. Leached amylose solution from cassava (CS_ AM) and mung bean (MB_AM), and two forms of amylopectin (AP) (granular; g and non-granular; ng) of waxy cassava (WxCS) starch were used. Four types of film matrices were fabricated and all TPS blend films contained same amount of AM and glycerol. Results displayed that molecular weight profiles of starch films and presence of granule remnants significantly controlled the film matrix formation, types of crystal formation, and percent of relative crystallinity (%RC) (p

不同基质淀粉共混薄膜的制备及其力学性能

摘要 本研究的目的是确定直链淀粉 (AM) 和淀粉颗粒的分子大小对热塑性淀粉 (TPS) 共混薄膜的机械性能的影响。使用了来自木薯 (CS_AM) 和绿豆 (MB_AM) 的浸出直链淀粉溶液，以及蜡质木薯 (WxCS) 淀粉的两种形式的支链淀粉 (AP)（颗粒状；g 和非颗粒状；ng）。制造了四种类型的薄膜基质，所有 TPS 共混薄膜都含有相同数量的 AM 和甘油。结果表明，淀粉膜的分子量分布和颗粒残留物的存在显着控制了膜基质形成、晶体形成类型和相对结晶度百分比 (%RC) (p
