| Summary: | This research aimed to synthesize and characterize physicochemical properties of
starch adipate nanoparticles (SANPs). SANPs was synthesized by esterification reaction of
native sago starch and adipic acid. The physical and chemical properties of SANPs were
characterized. Throughout the screening of the esterification, with the condition
temperature of 100°C and ethanol as precipitating media, gave the carbonyl group between
starch and adipic acid. Different molar ratio of sodium hydroxide and adipic acid were
used in synthesizing SANPs. The substitution of adipic acid onto starch chain was
confinned by FTIR spectroscopy and the degree of substitution (DS) as determined by the
back-titration method was within range of 0.004 - 0.366. |
