The effect of drying temperature and air velocity on the chemical composition, colour parameters, total
and resistant starch contents, bioactive and pasting properties of the taro flours were investigated in the
present study. For this aim, taro tubers were dried at different temperature (40, 50 and 60 C) and air
velocity (0.75, 1.25 and 2.00 m/s) levels. Generally all characteristics of the flours were significantly
affected by drying conditions. Resistant starch of the flours changed between 33.1 g and 51.4 g/100 g
flour and the flour produced at 50 C and 2.00 m/s had the highest resistant starch content. Total
phenolic content of the flours varied between 1.20 and 4.17 g GA/L and it generally increased with
increasing air velocity. Pasting properties of the starches were also markedly influenced and the flour
manufactured at 50 C with 0.50 m/s air velocity showed the lowest retrogradation and syneresis rate
considering setback values. Final viscosity of the taro flours ranged between 2219 and 3085 cP. The
results of the present study indicated that drying temperature and air velocity should be adjusted
regarding physicochemical properties of the taro flours, determining probable usage areas of the flours
