摘　　要：以翠冠梨为试材,采用微孔袋(CK)和PVC保鲜袋自发气调(MA)包装,-2^-1℃贮藏180 d,研究贮藏过程中腐烂率、糠心率、硬度、比重、纤维素和木质素含量等指标的变化。结果表明:除腐烂外,翠冠梨易糠心,导致酥脆感下降,主要表现为硬度和比重下降,纤维素含量上升,以及“按压有明显吱吱声”;翠冠梨可以耐受1.8%CO2,未发生高CO2伤害,这也是MA贮藏的首要和必要条件;MA贮藏对于翠冠梨腐烂和糠心具有显著的抑制作用。MA贮藏更有利于翠冠梨品质的保持,是一种长期贮藏的适宜方法。Cuiguan pear was packaged with micro-perforated(CK)or PVC(MA)bags,and stored at-2^-1℃for 180 days,the changes of decay rate,hollowing rate,firmness,specific gravity,cellulose and lignin contents and others indices during storage were investigated.The results showed that,except decay,Cuiguan pear was also prone to hollowing,which caused the decrease of crispness,mainly manifesting as decrease of firmness and specific gravity and increase of cellulose content,and‘obvious creak sound when pressing’.Cuiguan pear could tolerate 1.8%CO2 without high CO2 damage occurred,which was the first and necessary condition for MA storage.MA storage could significantly inhibit decay and hollowing of Cuiguan pear.MA storage was beneficial to maintaining the fruit quality and suitable for long-term storage of Cuiguan pear.
