Carbon dioxide snow preserves mushrooms

Mushroom spores die without a constant compost temperature

Farmed mushrooms grow on compost, that is permeated with mushroom spores. A specialist would speak about culture substrates. When transporting these substrates to the mushroom growers, the temperature of the mushroom spores in the compost may not exceed a permitted maximum, as otherwise the spores would die. This is where carbon dioxide, more specifically carbon dioxide snow, come into play: its cold temperature stops the fermentation (a natural fermentation process) in the compost and keeps the compost temperature constant during transportation. The mushroom spores are thus reliably preserved.
