Therefore, the overall objective of this study was to improve the basic knowledge about important parameters in the microwave drying of leafy herbs and to determine whether microwave drying could reduce the drying time and improve the product quality in terms of colour. Specific objectives were to:(a) evaluate the influence of microwave output power on drying kinetics and colour of parsley leaves; and(b) describe the drying process by producing athin layer drying model for the purpose of simulation and scaling up of the process.
