Convective drying and desorption isotherms of Shiitake (Lentinula edodes) mushroom
(2011) Müller, Joachim; Argyropoulos, Dimitrios
The drying behaviour of the Shiitake mushrooms was investigated in a through-flow laboratory dryer at temperatures of 30, 40, 50, 60 and 70 °C, corresponding relative humidity and constant air velocity of 1.0 m/s. The moisture desorption isotherms were also established at temperatures ranging between 20 and 70 °C by a hygrometric method. The Midilli model was described adequately the drying kinetics while the modified Halsey equation gave the most accurate fit to the experimental sorption data. The results indicated the significant influence of drying temperature on colour (p<0.05) and the insignificant effect on rehydration capacity (p>0.05).
