Modification of Starch Using Itaconic Anhydride and its Characterizations
Keyword(s):
In this study, the chemical modification of starch was conducted using itaconic anhydride as an esterifying agent. The results showed that sulphuric acid is more effective as a catalyst for esterification of starch compared to sodium hydroxide. The presence of attached itaconic anhyride in the starch affected the thermal behaviour and crystallinity of the resulting products as shown by the TGA, DSC, and the XRD data. In addition, the SEM micrographs also indicated that the modified starch exhibited a unique morphology in the form of block with different sizes ranging from 1 to 20 μm in length.
