Use of pennisetin-casein complex microparticles for Curcuma longa L. extract microencapsulation: Improvement of antioxidant and alpha-amylase inhibitory activities.

This study aimed to use a new protein complex of Pennisetin (Pen) a non gluten protein of pearl millet and casein (Cas), for curcumin (Cur) extract encapsulation using simple or complex coacervation. The potential improvement of Cur antioxidant activities and α-amylase inhibition after encapsulation was explored. Complex microparticles of Pen and Cas with various ratios exhibited average diameters ranging from 1.
