Efficient Stabilization and Directional-Controlled Release of Vitamin C in Disaccharide/Megasaccharide Composite Xerogels

Abstract

Front Cover: The combination of disaccharide trehalose and magasaccharide sacran in composite xerogel films effectively preserves vitamin C in a dry state. The cross-section FE-SEM images confirmed the presence of intercalated layered structures, supporting the existence of a striped structure with numerous lines along the longitudinal axis. Upon immersion in water, they exhibit anisotropic swelling behavior, releasing vitamin C preferentially from the edges, aiding dynamic control in sustained delivery systems.
