| 目的 改善气调贮藏双孢菇的技术方法，延长其货架期。方法 分析比较贮藏于4 ℃的不同气体成分下双孢菇的贮藏品质变化规律，并对不同处理组双孢菇在贮藏期间的色泽值、硬度、褐变程度、丙二醛（MDA）含量、呼吸强度及感官评价指标的变化进行分析对比。结果 在O2，CO2，N2的体积分数分别为9.6%，6.9%，83.5%时的低氧气调下，双孢菇各项指标品质劣变趋势最为缓慢，较适用于双孢菇的贮藏；L*值、硬度值与感官指标呈显著的正相关性，ΔE和MDA含量与感官指标呈显著的负相关性，均可作为反映双孢菇品质的重要指标。结论 O2，CO2，N2的体积分数分别为9.6%，6.9%，83.5%时，该气体比例下的双孢菇气调贮藏效果最佳，L*值、ΔE、硬度和MDA含量与感官品质之间的相关性最为显著。 |

| The work aims to improve the technical method for the modified atmosphere storage of Agaricus bisporus and prolong its shelf life. The change regulation of storage quality of Agaricus bisporus at 4 ℃ under different gas components was analyzed and compared. The changes of color, hardness, degree of browning, content of MDA, respiration intensity and sensory evaluation index of Agaricus bisporuses in different treatment groups were analyzed and compared. In the low oxygen modified atmosphere where the volume fractions of O2, CO2 and N2 were repesctively 9.6%, 6.9% and 83.5%, and all the indexes of the Agaricus bisporus were deteriorating at the most slow speed, which was quite suitable for the storage of Agaricus bisporus. There was a significant positive correlation between L* value, hardness and sensory index, and ΔE and MDA content were in a significant negative correlation with the sensory index, both of which could be used as an important index for the quality of Agaricus bisporus. When the volume fractions of O2, CO2 and N2 were repesctively 9.6%, 6.9% and 83.5%, the modified atmosphere storage effect of Agaricus bisporus in such gas ratio is the best, and the correlation between L* value, ΔE, hardness and MDA content and sensory quality is the most notable. |
