Abstract
In order to improve high hydrophilicity and low mechanical properties of biodegradable high-methoxy pectin (HMP) film, dialdehyde starch (DS) were introduced. In this study, different HMP/DS blended films were prepared by varying DS contents. It was observed from Infrared spectra that lower peak intensity of C=O stretching was detected after the incorporation of DS into HPM film. Moreover, moisture uptake of various HMP/DS blended films was found to be significantly lower than those of HMP film with the addition of low DS content. The improvement of mechanical properties was observed in various HPM/DS blended films. In addition, color parameters, swelling power, morphological and biodegradable properties of various HMP/DS blended films were also investigated.
