Abstract:
Starch is a natural, renewable and biodegradable polymer produced by many plants as a source of stored energy. It is the second most abundant biomass material in nature. Starch has a concentric semicrystalline multiscale structure. This structure allows the production of new nano elements through disruption of amorphous domain by acid hydrolysis. Current environmental concerns have turned starch nanoparticles into candidates of growing interest as bio-nanofiller for nanocomposite applications. In this study, the effects of different parameters, while the time of reaction was limited to 1 hr, on starch nano particles formation was investigated. A response surface methodology analysis has been undertaken. The average size of starch nanoparticle obtained in this study was 37.76 nm.
