Abstract

The present study aims to determine the effects of inlet air temperature and feed rate on the main powder properties during spray drying of roselle extract. A pilot-scale spray dryer was employed for the spray drying process. Parameters analyzed were yield, moisture, color and anthocyanin content. A factorial design with three inlet air temperatures (150, 160 and 170°C) and three feed rate levels (280, 350 and 420 ml/h) were investigated. There was significant (p<0.05) effect of inlet air temperature and feed rate on yield, color and moisture content while no remarkable changes in anthocyanin content was observed. Increase in feed rate substantially reduced (p<0.05) production of roselle powder. Furthermore, the amount powder was higher with elevated feed rate but lesser with increasing inlet temperature.
