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.
