本研究旨在评估麦芽糖糊精、阿拉伯胶和糊精对喷雾干燥器中获得的人心果浆粉末的酚类化合物、形态和流动性的影响。人心果浆的特征在于其水分和总多酚。将载体以 20% (m/m) 的浓度单独添加到纸浆中，并将样品在喷雾干燥器中干燥。分析粉末的水分、吸湿性、总多酚和颗粒形态，并使用粉末流动测试仪 (PFT) 评估它们的流动性。人心果浆的总多酚（100 g 浆固体中的平均 1055.30 mg GAE）比粉末（100 g 浆固体中 457.06 至 635.55 mg GAE）更显着。麦芽糖糊精的水分含量最低（1.16%）。所有载体均产生不吸湿的粉末。在含有阿拉伯胶的样品中，颗粒呈圆形，粗糙度更大。含有糊精的粉末具有更好的流动性，具有更高的流动指数和更低的压缩指数、豪斯纳比和壁摩擦角。人心果浆粉被分类为粘性的，流动指数 < 3，压缩指数从 53.2 到 59.9，豪斯纳比在 2.14 到 2.50 之间。使用的载体影响了人心果浆粉末的特性，阿拉伯胶促进了对总多酚和糊精的更好保护，从而产生更好的流动性特性。和壁面摩擦角。人心果浆粉被分类为粘性的，流动指数 < 3，压缩指数从 53.2 到 59.9，豪斯纳比在 2.14 到 2.50 之间。使用的载体影响了人心果浆粉末的特性，阿拉伯胶促进了对总多酚和糊精的更好保护，从而产生更好的流动性特性。和壁面摩擦角。人心果浆粉被分类为粘性的，流动指数 < 3，压缩指数从 53.2 到 59.9，豪斯纳比在 2.14 到 2.50 之间。使用的载体影响了人心果浆粉末的特性，阿拉伯胶促进了对总多酚和糊精的更好保护，从而产生更好的流动性特性。

Flowability of spray-dried sapodilla pulp powder

This study aimed to evaluate the influence of maltodextrin, Arabic gum, and dextrin on phenolic compounds, morphology, and flowability of sapodilla pulp powder obtained in a spray dryer. Sapodilla pulp was characterized by its moisture and total polyphenols. The carriers were individually added to the pulp at a concentration of 20% (m/m), and the samples were dried in a spray dryer. The powders were analyzed for moisture, hygroscopicity, total polyphenols, and particle morphology, and their flowability was evaluated using the Powder Flow Tester (PFT). Total polyphenols of sapodilla pulp (average of 1055.30 mg GAE in 100 g of pulp solids) were more significant than in the powders (457.06 to 635.55 mg GAE in 100 g of pulp solids). The lowest moisture (1.16%) was obtained for maltodextrin. All carriers generated nonhygroscopic powders. The particles showed a rounded shape with greater roughness in samples containing Arabic gum. The powder with dextrin resulted in better flowability characteristics, with a higher flow index and lower compressibility index, Hausner ratio, and wall friction angle. Sapodilla pulp powder was classified as cohesive, with flow indices < 3, compressibility index from 53.2 to 59.9, and Hausner ratio between 2.14 and 2.50. The carriers used influenced the characteristics of sapodilla pulp powders, the Arabic gum promoting greater protection of total polyphenols and dextrin resulting in better flowability characteristics.
