Embodiment 1
[0018] Preservation of matsutake:
[0019] 1) Pre-cooling treatment of matsutake: Select 10 kg of matsutake fruiting bodies with cap diameter ≥ 5cm, no umbrella opening, no insects, stipe length ≥ 7cm, and stipe diameter ≥ 3cm, and spread them on a tray or in a plastic frame. Pre-cooling at constant temperature for 2 hours at 4°C.
[0020] 2) Disinfection treatment: After the pre-cooling step, before putting into the modified atmosphere fresh box step, first fumigate with 1-methylcyclopropene with a concentration of 0.5 μl / L at 6° C. for 10 hours, and place matsutake fruiting bodies in the In the modified atmosphere fresh-keeping box described above, the modified atmosphere fresh-keeping box was placed in the cold storage at 4°C for pre-cooling, and at the same time, it was sterilized with ultraviolet light for 3 times, each time for 15 minutes, with an interval of 30 minutes.
[0021] 3) Vacuumizing and aeration treatment: After the pre-cooling step and disinfection step, th...
