摘要: 建立喷雾干燥法制备喀什小檗花色素的微胶囊工艺。采用单因素试验和正交试验筛选合适的壁材及配方,通过喷雾干燥法制备喀什小檗花色素的微胶囊产品。结果表明:花色素:壁材1:5、麦芽糊精:β-环糊精 1:6、固形物含量30%、乳化剂阿拉伯树胶1.0%、喷雾干燥进口温度160℃、出口温度80℃时,喀什小檗花色素的包埋率最高。稳定性实验表明微胶囊化的喀什小檗花色素对光、温度、碳水化合物、氧化剂、还原剂、金属离子等的稳定性都有一定程度的提高。

Abstract: One-factor-at-a-time combined with orthogonal array design method was employed to optimize the microencapslation condition of athocyanins extracted from the fruits of Berberis kaschgarica Rupr with 80% acidified aqueous ethanol solution three times for 15 min each time under the assistance of ultrasonic. The optimal microencapslation conditions for maximizing the microencapsulation efficiency of athocyanins from the fruits of Berberis kaschgarica Rupr were core-to-wall material ratio 1:5, maltodextrin-to-β-cyclodextrin ratio 1:6, solid content 30%, gum acacia amount 1.0%, inlet air temperature 160 ℃, and outlet air temperature 80 ℃. Athocyanins from the fruits of Berberis kaschgarica Rupr showed an increase in the stability towards light, temperature, carbohydrates, reducing agents, oxidants and metal ions after microencapsulation.

Key words: Berberis kaschgarica Rupr, anthocyanin, microencapsulation, stability
