Acerola ( DC.) is a sub-tropical and tropical fruit renowned for its high levels of vitamin C and phenolic compounds, which offer health benefits. This study aimed to optimize the spray drying process by determining the inlet and outlet temperatures using response surface methodology (RSM) with the central composite design. Additionally, it aimed to evaluate the release kinetics in the hydrophilic food simulation environment and the stability of the resulting powder under various storage temperatures. The RSM method determined the optimal inlet and outlet temperatures as 157 °C and 91 °C, respectively. High-accuracy prediction equations (R ≥ 0.88) were developed for moisture content (3.02%), process yield (91.15%), and the encapsulation yield of total polyphenol content (61.44%), total flavonoid content (37.42%), and vitamin C (27.19%), with a predicted monolayer moisture content below 4.01%, according to the BET equation. The powder exhibited good dissolution characteristics in the acidic hydrophilic food simulation environment and showed greater stability when stored at 10 °C for 30 days, compared to storage at 35 °C and 45 °C.
针叶樱桃（DC.）是一种亚热带和热带水果，以其富含对健康有益的高水平维生素C和酚类化合物而闻名。本研究旨在使用响应面法（RSM）和中心复合设计确定进、出口温度，以优化喷雾干燥工艺。此外，本研究旨在评估亲水性食品模拟环境中的释放动力学以及所得粉末在不同储存温度下的稳定性。响应面法确定的最佳进、出口温度分别为157℃和91℃。针对水分含量（3.02%）、工艺收率（91.15%）以及总多酚含量（61.44%）、总黄酮含量（37.42%）和维生素C（27.19%）的包封率，建立了高精度预测方程（R≥0.88），根据BET方程预测的单层水分含量低于4.01%。该粉末在酸性亲水性食品模拟环境中表现出良好的溶解特性，与在35℃和45℃储存相比，在10℃储存30天时表现出更高的稳定性。
