Our aim was to optimise the encapsulation of an aqueous bitter melon extract by\nspray-drying with maltodextrin (MD) and gum Arabic (GA). The response surface\nmethodology models accurately predicted the process yield and retentions of bioactive\nconcentrations and activity (R2 > 0.87). The optimal formulation was predicted and validated\nas 35% (w/w) stock solution (MD:GA, 1:1) and a ratio of 1.5:1 g/g of the extract to the stock\nsolution. The spray-dried powder had a high process yield (66.2% �± 9.4%) and high retention\n(>79.5% �± 8.4%) and the quality of the powder was high. Therefore, the bitter melon extract\nwas well encapsulated into a powder using MD/GA and spray-drying.
