摘　　要：为探讨O2/CO2主动自发气调在羊肚菌贮藏保鲜中的效果,设置O2/CO2初始体积分数分别为70%O2+30%CO2、80%O2+20%CO2、90%O2+10%CO2和100%O24个处理,以自然空气为对照,对在(4±0.5)℃贮藏过程中羊肚菌的生理生化及品质指标进行了定期测定。结果表明,适宜的初始O2/CO2比例能在气调箱内迅速达到气体平衡,延缓呼吸高峰的到来,降低羊肚菌失重率、多酚氧化酶活性及丙二醛含量,增加可溶性固形物、蛋白质及游离氨基酸含量,维持较高的感官品质。过高或过低的初始CO2比例,会易引起羊肚菌无氧呼吸或加快呼吸代谢,均不利于羊肚菌保鲜。试验中,以90%O2+10%CO2初始气体处理表现最佳。To study the effect of O2/CO2 active modified atmosphere packaging on storage quality of Morchella sextelata,initial O2/CO2 volume proportions of 70%O2+30%CO2,80%O2+20%CO2,90%O2+10%CO2,and 100%O2,were exploited,natural air(CK)was used as control.During storage at(4±0.5)℃,the of physio-chemical indicators and sensory quality of M.sextelata were periodically determined.The result showed that appropriate initial O2/CO2 proportion quickly reached gas balance in the modified atmosphere box,delayed the appearance of respiratory peak,reduced the weight loss rate,polyphenol oxidase activity,and malondialdehyde content,increased the soluble solids,protein and free amino acid content,and maintained higher sensory quality of morel.However,too high or low initial CO2 proportion easily caused the anaerobic respiration or accelerate the respiratory metabolism,those were both inconvenienced to the preservation of M.sextelata.In this experimental,the best initial gas proportion was 90%O2+10%CO2.
