Embodiment Construction
[0017] (1) Avoid spraying water 2-3 days before harvesting edible fungi, and spray a small amount of natural biological preservatives (chitosan, polylysine, kojic acid, cinnamon oil, clove oil, etc.) Harvest the surface of the mushroom body (fruiting body) carefully, put it in a foam box with a polyethylene plastic bag to avoid damage to the edible fungus, and put it in a cold storage for 12-24 hours.
[0018] (2) Weigh and pack 100-500g of pre-cooled edible fungus into a 20-50cm×30-50cm polyethylene vacuum packaging bag, and then put in 10-30g of food desiccant (silica gel, montmorillonite or bentonite) And 5-30g of activated carbon, and avoid direct contact between edible fungus and desiccant and activated carbon.
[0019] (3) The vacuum sealing machine first evacuates, then fills the mixed gas of oxygen and nitrogen (the partial pressure of the mixed gas is oxygen: nitrogen = 50-100: 50-0) to atmospheric pressure, seals, and packs.
[0020] (4) The boxed edible fungi are s...
