| Rice starch/carboxymethyl cellulose from durian rind (RS/CMCd) biocomposite films were prepared. The effect of ratios between RS and CMCd were used in a film forming solution on transparency, color, morphology, and mechanical properties of RS/CMCd composite films was investigated. Each RS/CMCd composite film was translucent. A higher amount of CMCd affected the transmittance at 660 nm of these composite films increased and the absorbance decreased. When the CMCd content increased, L*, a* and WI (whiteness index) value of the composite films decreased while b* and E value increased. Scanning electron microscopy (SEM) revealed homogenious crosssectional surface for the pure RS and CMCd film while the other RS/CMCd composite films showed the rough surface.... |
