Enhancing Stability of Boesenbergia rotunda Bioactive Compounds: Microencapsulation via Spray-Drying and Its Physicochemical Evaluation

This study aimed to microencapsulate Boesenbergia rotunda (fingerroot) extract using mal- todextrin (MD) and gum arabic (GA) as wall materials via spray-drying to improve powder physicochemical properties and protect bioactive compounds. MD and GA were employed as wall materials in varying ratios (MD:GA of 1:0, 0:1, 1:1, 2:1, 1:2) to evaluate their effects on the physicochemical properties of the resulting microcapsules. Spray-dried microcapsules were evaluated for morphology, flowability,...
