摘　　要：研究了双孢蘑菇在2℃和20℃下,不同薄膜包装中O_2、CO_2体积分数在蘑菇呼吸作用及薄膜渗透作用下的动态变化,结果表明低温和气调条件能有效抑制其呼吸作用。采用Michaelis-Menten型酶动力学方程,建立了2种温度下双孢蘑菇呼吸速率随O_2、CO_2体积分数变化的数学模型,同时考察了不同包装薄膜厚度对呼吸模型参数的影响,为气调包装参数的选择提供了理论基础。The dynamic changes of the oxygen and carbon dioxide volume fraction of Agaricus bisporus which were packaged in three kinds of film with different thickness were studied at 2℃and 20℃.The results indicated that low temperature and MAP could inhibit the respiration of mushroom.A respiration model,based on Michaelis-Menten type enzyme kinetics,was proposed for predicting respiration rates of Agaricus bisporus as a function of O_2 and CO2 volume fraction at the storage temperature of 2℃and 20℃,which is essential to the design of modified atmosphere package.
