Encapsulation of was performed using spray and freeze-drying. Maltodextrin and gum arabic were used in different combinations for spray-drying. Values of 50% maltodextrin and 40% gum arabic gave best results. Spray-drying was done at temperatures ranging from 110 to 150oC. Survivability, acid tolerance, antibiotic sensitivity testing, and total anthocyanin content and physical properties of moisture content, water activity, color analysis, bulk density, and tap density were analyzed. The moisture content of encapsulated powders ranged from 6.51 to 7.72% (wet basis) and bulk density and tap density values ranged from 0.334 to 0.308 g/cm and 0.350 to 0.330 g/cm, respectively. Total anthocyanin contents were 19.28 and 7.264 mg/100 mL, respectively, for freeze and spray-dried powders. Freeze-dried probiotic pomegranate juice powder yielded best results with high survivability of , a high total anthocyanin content, and other properties.
采用喷雾干燥和冷冻干燥法对[具体物质]进行包封。将麦芽糊精和阿拉伯胶以不同组合用于喷雾干燥。50%麦芽糊精和40%阿拉伯胶的组合效果最佳。喷雾干燥在110至150℃的温度范围内进行。分析了存活率、耐酸性、抗生素敏感性测试、总花青素含量以及水分含量、水分活度、颜色分析、堆积密度和振实密度等物理性质。包封粉末的水分含量范围为6.51%至7.72%（湿基），堆积密度和振实密度值分别为0.334至0.308 g/cm³和0.350至0.330 g/cm³。冷冻干燥和喷雾干燥粉末的总花青素含量分别为19.28和7.264 mg/100 mL。冷冻干燥的益生菌石榴汁粉末在[具体益生菌]的高存活率、高总花青素含量和其他性质方面取得了最佳效果。
