  Extraction, purification and synthesis of acetylated cassava starch was undertaken. The degree of modification for the acetylated (modified) starch was calculated to be 0.03. Physicochemical indices interrogated were all significantly (P<0.05) affected by the acetylation. Microstructural studies revealed starches that were predominantly polygonal in shape. The FTIR results confirmed introduction of an acetyl group with a new band at 1728 cm-1. The results further show that, the modification did not degrade the granule morphology, but x-ray pattern showed increased crystallinity in the acetylated derivative. Thermogravimetric analysis and differential scanning calorimetry revealed 2 phase decomposition of both starches and improved gelation capacity with new peaks respectively. Rifampicin (RIF) loaded starch-stabilized silver nanoparticles yielded good mean particle size (248 nm), p.. View More»
