Abstract Rapeseed and honeydew honey were spray dried by dehumidified air, with NUTRIOSE® as a drying carrier, to create a product with prebiotic properties, in line with current "clean label" trend. Because of the low inlet air humidity, drying temperature was decreased (inlet/outlet: 75/50 °C). Such an approach gave the possibility to reduce the amount of added carrier. Thus, honey powders containing 80% of honey solids were produced and characterized. Drying was performed with very high powder recovery (84.4–93.9%), especially in the variants containing 80% of honey solids. Although there were some differences in the physical properties between powders produced by the application of dehumidified air and by the traditional spray drying (but containing the same ratio of honey to carrier), the overall properties were comparable: low water content (below 2.5%) and low water activity (below 0.2), medium or high cohesiveness, high hygroscopicity (above 20%), bed porosity between 50 and 70%.

除湿空气在油菜籽和蜜露蜂蜜喷雾干燥中的应用——工艺性能和粉末特性的考虑

摘要 菜籽蜜和蜜露蜜通过除湿空气喷雾干燥，以NUTRIOSE®为干燥载体，创造出具有益生元特性的产品，符合当前“清洁标签”的趋势。由于入口空气湿度低，干燥温度降低（入口/出口：75/50 °C）。这种方法提供了减少添加载体量的可能性。因此，生产和表征了含有 80% 蜂蜜固体的蜂蜜粉末。以非常高的粉末回收率 (84.4–93.9%) 进行干燥，尤其是在含有 80% 蜂蜜固体的变体中。尽管使用除湿空气和传统喷雾干燥（但蜂蜜与载体的比例相同）生产的粉末在物理性质上存在一些差异，但总体性质是可比的：
