摘要

以5～30wt%甘油为增塑剂，通过溶液浇铸法制备了基于3wt%菠萝蜜种子淀粉的热塑性薄膜。本研究的目的是研究甘油对薄膜力学性能的影响。根据分析，薄膜的最佳拉伸强度为4.40MPa，这表明在甘油存在下，天然淀粉颗粒转化为连续相，如扫描电子显微镜所示。甘油在淀粉中的掺入也显示出氢键的形成，傅立叶变换红外光谱证明了这一点。

THE EFFECTS OF GLYCEROL ADDITION TO THE MECHANICAL PROPERTIES OF THERMOPLASTIC FILMS BASED ON JACKFRUIT SEED STARCH

Thermoplastic films based on 3 wt.% jackfruit seed starch were prepared using 5 to 30 wt.% glycerol as plasticizer via solution casting method. The aim of this study is to investigate the effect of glycerol on the mechanical properties of films. According to the analysis, the optimum tensile strength of the film was obtained at 4.40 MPa, which revealed that the native starch granules were converted into a continuous phase in the presence of glycerol as indicated by scanning electron microscopy. The incorporation of glycerol in starch also showed the formation of hydrogen bond evidenced by Fourier transform infrared spectroscopy.
