Pomegranate juice powder production

This research has been done to find out optimize process conditions for producing pomegranate juice powder by spray dryer. To do so a pilot scale spray dryer was used and the effects of different parameters were determined. The result show that Malt dextrin with De=6 as drying aid with fruit juice to Malt dextrin ratio equal to 35 65 and %0.3 zincstearate for free flowing state give best product quality. Dryer chamber temperature was 120 degree of centigrade, atomizer rpm was 1400, input to output air temperature was 103 170 and feed flow rate was 36 CC/MIN. Properties of pomegranate juice and pomegranate juice powder were analyzed and has been reported.
