Preparation, Characterization, and In Vitro Digestion Behavior of Alginate-Chitosan Microspheres Loaded with <i>Ziziphus jujuba</i> Pulp.

ABSTRACT: In this study, sodium alginate-chitosan composite microspheres (S-C Ms) were prepared by ionic gelation to encapsulate Ziziphus jujuba pulp from wild jujube pulp. The effects of sodium alginate (SA) concentration, chitosan (CS) concentration, and core-to-wall ratio on encapsulation efficiency (EE%) and loading capacity (LC%) were systematically investigated. The results showed that both EE% and LC% were maximized when the SA concentration was 2.0% (w/v) and the CS concentration was 1.5% (w/v). The FTIR and XRD analyses confirmed the successful encapsulation of a phenolic-rich extract from Z. jujuba pulp (PRE) and its transformation into an amorphous state, while the SEM observations revealed that the composite microspheres possessed a well-defined
