Temperature & Controlled Atmosphere
Optimum Temperature
0°C-1.5°C (32°F-35°F) Storage life is typically 5-7 days at 1.5°C (35°F) and 2 days at 4.5°C (40°F).
Optimum Relative Humidity
95-98%
High relative humidity is essential to prevent desiccation and loss of glossiness. Drying is correlated with blackening of the stipe and gills and curling of the cap. Commonly mushrooms are packed and shipped in cartons with a perforated overwrap to maintain high humidity.
