Abstract: Stevia is a natural non-caloric substitute to conventional sugar. The objective of this study was to investigate the effect of solar convective drying on kinetics and quality attributes of stevia leaves grown in Morocco. The evaluated drying temperatures were 50, 60, 70 and 80 °C with an air flow of 300 and 150 m3/h.
