Effects of open-air sun drying and pre-treatment on drying characteristic of purslanes (Portulaca oleracea L.) were investigated. Drying times were determined as 31, 24 and 9 h for natural, salted and blanched, respectively. The higher "L" value and lower "-a/b" ratio values were obtained in natural dried purslane. The Aghbashlo et al. model gave a better fit to drying data.
