硅窗气调保鲜贮藏茶树菇的化学及生理变化研究

Chemical and Physiological Changes of Agrocybe chaxingu Huang during Controlled Atmosphere Storage with Silicon Gum Film Window

茶树菇在10%O2、10%CO2、80%N2和10%O2、15%CO2、75%N2的气体浓度下,分别用有硅窗和没有硅窗的聚丙烯盒包装,在3±1℃温度下贮藏20d,对贮藏期间盒内的气体组成、茶树菇的呼吸强度、VC含量、总酸、可溶性固形物含量、电导率及蛋白质含量进行定期检测。结果表明:有硅窗和没有硅窗存在对检测指标有显著差异,硅窗有良好的气体交换性能,能保证茶树菇贮藏在适宜的气体环境中,化学和生理变化缓慢,有利于茶树菇品质的保存。初始气体浓度对茶树菇的贮藏品质保存也有一定的影响,有硅窗、10%O2、10%CO2、80%N2的处理条件能保证整个贮藏期间O2浓度都在1.5%以上,而CO2的浓度都在12.6%以下,最适合茶树菇的贮藏。

Agrocybe chaxingu Huang were stored in the packages with or without silicon gum film window in different controlled atmospheres (10% O2, 10% CO2, 80% N2 or 10% O2, 15% CO2 and 75% N2) at 3 ± 1℃. Then changes of gas composition in the packages, respiration rate, ascorbic acid content, total acid content, soluble solid content, conductivity and protein content were examined. The results showed that there are significant differences in all examined parameters between the packages with and without silicon gum f...
