Abstract: Throuth orthogonal test , the study covered the effects on the rate of cap opening , PPO activity and ADF by controlling concentration of NaCl, time of colour fixation and storage temperatures. The result indicated that with proper handing to treatment mushrooms could significantly reduce the cap opening and quality deterioration during storage. The experimented results was further analogged by using regression equation. The estimated values were found to be identical with the measured values. Compared with regular low-temperature storage, the mushrooms had better quality and physical-chemical index in low-temperature and controlled atmosphere storage.
