Abstract

The study reports the production of an innovative functional orange powder supplemented with probiotics and prebiotics, by implementing new ecofriendly and sustainable technologies, such as spray drying. The survival of Lactobacillus casei shirota, Lactobacillus casei immunitas and Lactobacillus acidophilus johnsonii, during spray drying in orange juice was proven and the stability of the powder obtained at room temperature and at 4 °C was investigated. Furthermore, the study highlighted the possibility to enhance the pectin obtained from the food agroindustry as a carrier for the spray-drying process. Combining maltodextrins and pectins at a 10:1 weight ratio. The study showed the efficiency of the maltodextrin/pectin mixture as carriers for the spray-drying process and the viability of the tested microorganisms during both the storage at room temperature and at 4 °C, showing that the latter represents the best storing condition for a longer viability of the microorganisms.
