Curcumin loaded core-shell biopolymers colloid and its incorporation in Indian Basmati rice: An enhanced stability, anti-oxidant activity and sensory attributes of fortified rice.

Curcumin, a major bioactive in curcuminoids and food colorant, possess therapeutic properties, however, its low water solubility, instability during processing limit its industrial applications. The nanoencapsulated curcumin (NEC) in sodium caseinate (SC) and Maillard conjugate (MC) showed >90% water solubility. Encapsulation in MC reduced particle size (150 to 120 nm) zeta potential (-34 to -45 mV) and improved encapsulation efficiency (74 to 94%) compared to SC under optimized Tween20 and salt-ions.
