Abstract: High temperature and high humidity drying of lotus root chips was studied. Results indicat that lotus root chips texture has less contract, drying rate is speedy, and oxidative browning can be controled greatly. The final product has good color and transpareny. The chips are quite tender and crisp and the flavor is very strong after rehydration of 2min. Optimum drying condition is: preheat 3min, temperature 90℃,relative humidity 20%; earlier stage temperature 90℃, relative humidity 60%, drying 20min; later stage temperature 50℃, relative humidity 20%, drying 10min. Air speed 2.2m/s.
