Abstract
Freeze drying is started with the process of freezing the material then continued with a control pressure of vacuum conditions and at temperatures below the freezing point in order to change phase from a solid into a vapor (sublimation process). The sublimation process ended when the material becomes supersaturated and begins to crystallize. The aimed of this research was to study the effects of variation of lactose concentration as fillers on the quality of passion fruit granules of freeze drying results. Research done by adding fillers into the passion fruit pulp on variation of concentrations of 10, 20, 30, 40, and 50%, then dried using vacuum freeze dryer. The parameters observed were moisture content after drying. The experimental design used was complete random design single factor with three replicates. The results showed that the variation of filler concentration had different significantly to moisture content of passion fruit granules of freeze drying results. The higher of the filler concentration of added, the lower of moisture contents of passion fruit granules was produced.
