| Abstract | The main purpose of this work was to study the effect of carrier agents on the drying capability and the qualities of tamarind powder produced by a drum dryer. Two popular carrier agents, namely maltodextrin and modified starch, were applied to tamarind juice at juice-to-carrier-agent ratios of 1:0.3, 1:0.4, 1:0.5, 1:0.6, 1:0.7 and 1:0.8 (w/w). A double drum dryer was employed in this work at a drying temperature of 140?C, drum rotational speed of 0.50 rpm and gap between drums of 0.15 mm. The efficiency of carrier agent was evaluated by the capability of drying and product qualities such as product recovery, bulk density, total solid, moisture content and color difference. The results of the experiment indicated that the ratio of the carrier agent affected the drying capability. The tamarind powder were easily removed from the drums by doctor blades without sticking at the lowest ratios of moltodextrin and modified starch of 1:0.6 and 1:0.4, respectively. Furthermore, when considering the qualities of tamarind powder, as a carrier modified starch led to better tamarind powder qualities than maltodextrin |
