Dehydrated cranberry juice powder obtained by osmotic distillation combined with freeze-drying: Process intensification and energy reduction
The aim of this work was the study of the energy efficiency of the dehydration process of
cranberry juice using osmotic distillation (OD) in combination with freeze-drying. To achieve
this process, OD was performed on a hollow fiber membrane contactor with an initial sugar
content of 8° Brix in the cranberry juice. This solution was concentrated to four different final
concentrations (25, 35, 45 and 57° Brix) with the purpose of reducing the lyophilization time
obtaining a 100% dried product, using as a response variable the processing time. From …
