Our aim was to optimise the encapsulation of an aqueous bitter melon extract by spray-drying with maltodextrin (MD) and gum Arabic (GA). The response surface methodology models accurately predicted the process yield and retentions of bioactive concentrations and activity (² > 0.87). The optimal formulation was predicted and validated as 35% (w/w) stock solution (MD:GA, 1:1) and a ratio of 1.5:1 g/g of the extract to the stock solution. The spray-dried powder had a high process yield (66.2% ± 9.4%) and high retention (>79.5% ± 8.4%) and the quality of the powder was high. Therefore, the bitter melon extract was well encapsulated into a powder using MD/GA and spray-drying.
我们的目标是通过用麦芽糊精（MD）和阿拉伯胶（GA）进行喷雾干燥来优化苦瓜水提取物的包封。响应面法模型准确预测了工艺产率以及生物活性成分浓度和活性的保留率（R²>0.87）。预测并验证的最佳配方为35%（w/w）储备溶液（MD:GA，1:1）以及提取物与储备溶液的比例为1.5:1 g/g。喷雾干燥粉末具有较高的工艺产率（66.2%±9.4%）和高保留率（>79.5%±8.4%），且粉末质量较高。因此，使用MD/GA和喷雾干燥可将苦瓜提取物很好地包封成粉末。
