流通过程中外包装和环境温度对双孢蘑菇速冻品品质的影响

Effect of Outer Packing and Environmental Temperature on Quality of Quick-frozen Agaricus Bisporus during Logistics

模拟速冻食用菌流通过程中,冷链中断后外包装和环境温度对速冻食用菌品质的影响。结果表明,冷链中断后速冻双孢蘑菇的水分含量由93.30%下降到90.96%以下;随着冷链中断时间的延长,速冻双孢蘑菇的菌落总数呈先升高后降低的趋势。当外界环境温度为5±0.5℃,运输时间少于7 h;外界环境温度为15±1℃时,运输时间少于5 h,以及外界环境温度为25±2℃时,运输时间少于2 h的3种情况下,可用泡沫箱等保温运输食用菌速冻品。

The article simulates on the effect of outer packing and environmental temperature after cold chain interruption on quality during transport of quick-frozen Agaricus bisporus. The results show that： moisture content decreased from 93.30% to less than 90.96% during the cold chain interruption time. As the extension of the cold chain interruption time, the total plate count of frozen Agaricus bisporus reduced after the first rise trend. Under three conditions as the temperature of the external environment for 5±0.5℃, and the logistics time is less than 7 h, the temperature of the external environment for 15±1℃, and the logistics time is less than 5 h, the temperature of the external environment for 25±2℃, and the logistics time is less than 2 h, the quick-frozen products edible mushroom can be transported with heat preservation such as foam box.
