Nanoparticles for Synergistic Delivery of Curcumin and Quercetin Based on Zein and Sodium Caseinate: Preparation, Characterization, and Intestinal Absorption.

ABSTRACT: The purpose of the study was to characterize the basic structure of nanoparticles (Zein-CS-Cur-Que) embedded in curcumin and quercetin, realize the synergistic antioxidant of dietary polyphenols, and improve the transmembrane transport rate and bioavailability of curcumin. The oral delivery system Zein-CS-Cur-Que developed based on the synergistic encapsulation of curcumin and quercetin using the anti-solvent method with corn alkyd-soluble proteins and sodium caseinate possessed varying nanoparticle sizes (173.96-191.03 nm) and good dispersibility (PDI < 0.17), and relied on electrostatic interactions, hydrogen bonding, and hydrophobic interactions to successfully encapsulate curcumin (94.62%) and quercetin (73.75%). The results showed that Zein-CS-Cur-Que enhanced the stability and antiox
