CHARACTERIZATION OF CURCUMIN LOADED STARCH NANOPARTICLES FROM NATIVE CASSAVA AND POTATO STARCHES

Tóm tắt

The objective of this study was to investigate the characteristics of curcumin loaded starch nanoparticles, formulated from native cassava and potato starches using the nanoprecipitation method. Curcumin was loaded during the formation of starch nanoparticles at a certain ratio. The results showed that curcumin loaded in the starch nanoparticles from 1% potato starch solution achieved the highest loading efficiency, loading ability, and solubility. The curcumin loaded starch nanoparticles from 2% native cassava starch and 2% native potato starch performed the higher antioxidant ability and direct UV irradiation protection. TEM analysis demonstrated that curcumin loaded starch nanoparticles had a spherical shape with the mean diameter of 80 ± 8 nm. This means curcumin was successfully loaded into starches by applying the simple nanoprecipitation method.
