Abstract: Boiling and drying are the essential steps followed in processing of turmeric rhizomes. Superheated steam was employed for boiling and subsequent drying of rhizomes in a superheated steam dryer. Overall dimensions namely length, width and thickness of the rhizomes, significantly (p< 0.05) increased with boiling whereas significantly decreased with drying process. Bulk density of the fresh, boiled and dried rhizomes were found to be 530.9, 510.1 and 640.8 kg/m3. Boiling process showed 10% increase in volume of the boiled rhizomes and 30% decrease in volume under drying process when compared to fresh rhizomes. Porosity of the rhizomes increased from 54.11 to 55.18 under boiling and decreased to 47.04 under drying process.
