摘要
为实现双孢蘑菇高氧气调包装系统设计,以新鲜双孢蘑菇为材料,采用高氧气调包装方式,分别应用Weibull模型、Logistic模型研究双孢蘑菇高氧气调包装内O2和CO2浓度变化,对双孢蘑菇呼吸速率进行预测。结果表明,贮藏50 h后,高氧气调包装袋内的O2分压由最初80 kPa下降到50 kPa,对照处理袋内O2浓度缓慢下降,不同包装方式袋内CO2浓度随贮藏时间逐渐升高,在贮藏后期,CO2浓度逐渐趋于平缓。包装袋内的O2、CO2分压测定值与预测值拟合较好。CO2产生速率很好地反映了双孢蘑菇高氧气调包装过程中呼吸速率的变化。
In order to design the high-oxygen modified atmosphere packaging in mushroom （Agaricus bisporus） , Weibull model and Logistic model were applied to study in-package 02 and CO2 concentration and predict the respiration of mushroom. The results showed that 02 concentration in high oxygen package decreased from initial 80 kPa to 50 kPa after 50 h, while it declined slowly in control. The CO/ concentration under both treatments increased gradually, and it reached the maximum value at the end of storage. The predicted concentration of 02 and CO2 fitted well with the experimental value. The respiration of mushroom under high oxygen was well described by the CO2 production rate.
