Popis:	The aim of the present investigation was to study the various physical properties of the spray dried tomato powder. The spray drying process was operated at maltodextrin concentration (3%), air inlet temperature (152 0C), feed flow rate (37 ml/min) and blower speed (1300rpm). Moisture content, bulk density, tapped density, flowability and water solubility index of the spray dried tomato powder were analyzed. Powder samples showed moisture activity of 4.40% and water activity of 0.47, which is good for powder stability. Powder samples showed excellent flowing properties with Hausner ratio of 1.18 and Carr index of 12.82%. The reconstitution property (water solubility index) was found to be 92.50%.
