Anthocyanin-rich extract obtained from black chokeberry () pomace was microencapsulated with spray drying by using different wall materials, , maltodextrin with dextrose equivalent 6 (MD6), maltodextrin with dextrose equivalent 20 (MD20) and the combination of MD20 with gum Arabic (MD : GA, 15 : 5 w/w), whey protein isolate (MD : WPI, 19 : 1 w/w), and xanthan gum (MD : XG, 19.5 : 0.5 w/w). Spray drying conditions were chosen as follows: inlet temperature of 150 °C, outlet temperature of 90 °C, 4.5 mL min feed flow rate, 0.357 m h air flow rate, and an aspirator capacity of 100%. Physicochemical characteristics of the powders such as moisture content, particle size, capsule morphology, color, spray drying yield, encapsulation efficiency, total anthocyanin content, total and individual phenolic content, and total antioxidant activity were investigated. With all the parameters evaluated, MD : GA wall material provided better results particularly in terms of production yield and encapsulation efficiency. To conclude, black chokeberry by-product can be used as a source of polyphenols to produce value-added colored powders with bioactive properties which might have the potential to be used in food, nutraceutical and cosmetic industries.
采用喷雾干燥法，以不同壁材（MD6 麦芽糊精、MD20 麦芽糊精、MD20 阿拉伯胶（MD:GA，15:5 w/w）、乳清蛋白分离物（MD:WPI，19:1 w/w）和黄原胶（MD:XG，19.5:0.5 w/w））对黑果腺肋花楸（）废渣中的花色苷进行微胶囊化。喷雾干燥条件为：进口温度 150°C，出口温度 90°C，进料流量 4.5mL/min，空气流量 0.357m/h，吸气器容量 100%。研究了粉末的物理化学特性，如水分含量、粒径、胶囊形态、颜色、喷雾干燥收率、包埋效率、总花色苷含量、总酚和单体酚含量以及总抗氧化活性。在所评估的所有参数中，MD:GA 壁材的效果更好，特别是在产率和包埋效率方面。总之，黑果腺肋花楸副产物可作为多酚类物质的来源，生产具有生物活性的附加值有色粉末，这些粉末可能具有在食品、营养保健品和化妆品行业中应用的潜力。
