Fabrication and characterization of ß-cyclodextrin-epichlorohydrin grafted carboxymethyl chitosan for improving the stability of Cyanidin-3-glucoside

Cyanidin-3-glucoside (C3G), an anthocyanin constituent of fruits and vegetables. It has been proven to possess numerous health benefits with no side effects. However, the poor stability of C3G is an intractable property that limits its application. Hence, the aim of this study is to improve the stability of C3G through the formation of well dispersed nanoparticles. In this study, C3G loaded ss-CD-EP-CMC nanoparticles exhibited nearly spherical with good disperse and homogeneous morphology. Results also indicated that the nanoparticles formation of grafting of C3G to ss-CD-EP-CMC could significantly improve the stability of C3G to against thermal or light degradation. Collectively, current results strongly aligned with the prospective purpose that the grafting of C3G to ss-CD-EPCMC nanoparticles could be treated as an effective approach for improving the stability. This study opens a new avenue for the utilization and development of novel wall materials ss-CD-EP-CMC in C3G associated nutraceutical.
