摘　　要：为保持双孢菇贮藏品质、延长货架期,研究气调包装对双孢菇保鲜效果的影响。采用不同浓度配比的气体吸收剂和不同厚度聚乙烯薄膜对双孢菇进行包装,置于4℃下贮藏,定期测定双孢菇的表面颜色,呼吸强度、失重率、硬度、PPO、POD活性的变化。结果表明:采用组成为1.44 g脱氧剂0、.5 g乙烯脱除剂1、.2 g二氧化碳脱除剂的气体吸收剂及厚度为0.05 mm的聚乙烯薄膜,对双孢菇贮藏中的褐变具有明显的抑制作用,能够有效降低双孢蘑菇呼吸强度,延长双孢菇的贮藏保鲜期。In order to keep the quality and increase shelf life of Agaricus bisporus,the effect of modified atmosphere packaging on quality of Agaricus bisporus was studied.Agaricus bisporus were packaged in different initial gas absorbing concentration and different thickness of polyethylene film,then stored at 4 ℃ respectively,and surface color,respiration intensity,weight loss,hardness,PPO and POD＇s activity were determined regularly.The different content of gas absorbent and different thickness of polyethylene film were used to pack the fresh Agaricus bisporus,and then put up fresh-keeping tests with low-temperature.The results showed that,1.44 g deoxidizer,0.5 g ethylene scavengers,1.2 g carbon dioxide scavengers,and 0.05 mm polyethylene film had a clear inhibition on the browning of Agaricus bisporus,and could effectively reduce the respiration rate and prolong the storage life of Agaricus bisporus.
