| Abstract: | The relations of temperature and water fraction versus drying time during freeze drying of mushroom have been studied.The mathematical model of freeze drying of sublimation-adsorption-desorption was developed based on the energy and mass conservation in dried and frozen regions of mushroom respectively.Experimental values fit well with calculated results. |

| Keywords: | freeze drying mushroom sublimation-adsorption-desorption model fibrous porous materials |
