| Abstract | The u se of spray drying, drum drying and for dehydrating fruit juices was studied. concentrate was successfully dehydrated using technique. vacuum-puff drying Pineapple juice vacuum-puff drying The effect of pineapple juice composition e.g. TSS, pulp and process parameters e.g. temperature on the quality of powder obtained in terms of color change and reconstitution time was found among the powder samples o btained from different trials. The effect on TSS content, ascorbic acid (equivalent ) , citric acid (equivalent ) and pH of different powder samples was found to have non- significant difference. Best sample was selected on the basis of col or change and reconstitution time . This sample was tested for various physical properties and sensory evaluation. The sensory evaluation test for color, and taste and flavor of the reconstitute d juice revealed a slight difference from the controlled sample . Moisture content of powder samples was found to have significant effect on their bull< densities. The linearity of the Sone's mode l was proved in the drop test. The samples of different moisture content behaved differently when tested in drop test and in mechanical compaction test . |
