The change of respiration rate of Agaricus bisporus , packed in film, with storage time was studied at the storage temperature of 5℃、10℃、15℃、20℃ and 25℃. The results indicated that the mushroom respiration rate showed a significant decrease with increasing storage period until dynamic equilibrium. A respiration model of Agaricus bisporus, based on Langmuir adsorption theory, was proposed at different temperatures. The results suggested that the mushroom respiration rate increased with increasing of O2 concentrations, and decreased with increasing of CO2 concentrations. The maximum rate increased with temperature, and the relationship between maximum rate and temperature was well described by the Arrhenius equation.
