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.%研究了不同温度(5、10、15、20、25℃)下,气调包装的双孢蘑菇呼吸速率随贮藏时间的变化规律.结果表明,双孢蘑菇的呼吸速率随着贮藏时间的延长而不断降低,直至达到动态平衡状态.利用Langmuir吸附理论对双孢蘑菇呼吸速率的测定值进行了解析,建立了不同贮藏温度下的呼吸速率模型.结果显示,双孢蘑菇的呼吸速率随贮藏环境中O2体积分数的增加而升高,随CO2体积分数的增加而降低;最大呼吸速率随温度的增加而增加,且与贮藏温度之间满足Arrhenius方程.
