In this study, drying behavior of mushrooms was investigated. The experiments were carried out under both laboratory and shady-and sunny-atmospheric conditions. Drying curves were presented for each experiment. It was concluded that mushrooms can be dried in the cupboards by using air at 50°C of temperature in a time period of 5 to 6 hours, and the mushrooms dried must be protected in a medium without air (in vacuum). The uncertainty error rate of drying is about 22 %.
