Abstract: The present research aims to study the effect of indirect solar drying by airflow orientation on some physicochemical parameters of mango. The mangoes harvested at physical maturity were exposed in the drying chamber. The temperature and humidity sensors were placed inside and outside the dryer. For different airflow modes (surface airflow mode, direct airflow mode and crossed airflow mode). Temperature, humidity, irradiance and mass loss readings were taken on two mangoes samples. Acidity, pH, moisture and vitamin C contents were determined on dried mango slices in different modes. The kinetics of drying shows that the moisture loss of mangoes is faster for thin slats. Times for drying are 17, 22 and 30 h, respectively for the licking mode, mixed and through. The conservation of physicochemical properties varies, respectively for 47.5, 43.8 and 33.02% for licking, mixed and through mode. The flux variation influences the physicochemical parameters of the dried mango.
