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% (<i>w</i>/<i>v</i>) and the CS concentration was 1.5% (<i>w</i>/<i>v</i>). The FTIR and XRD analyses confirmed the successful encapsulation of a phenolic-rich extract from <i>Z. jujuba</i> pulp (PRE) and its transformation into an amorphous state, while the SEM observations revealed that the composite microspheres possessed a well-defined Foods (Basel, Switzerland)Preparation, Characterization, and In Vitro Digestion Behavior of Alginate-Chitosan Microspheres Loaded with <i>Ziziphus jujuba</i> Pulp.PMC128965312024YFD21007042023CXGC010717Chen NYu MWang FZhang LRong ZZhang QDai YLiu XXie FZhao DJu MZhang BFan BfalsePreparation, Characterization, and In Vitro Digestion Behavior of Alginate-Chitosan Microspheres Loaded with <i>Ziziphus jujuba</i> Pulp.In this study, sodium alginate-chitosan composite microspheres (S-C Ms) were prepared by ionic gelation to encapsulate <i>Ziziphus jujuba</i> pulp from wild jujube pulp.
