Drying (or dehydration) is an ancestral preservation method through which the mushrooms' water content is removed. This method promotes the preservation of mushrooms without denaturing them, giving a result close to the mushroom's "fresh" state, as it retains all its organoleptic qualities. Drying mushrooms allows them to be preserved in a natural way and does not alter, or only slightly alters, their taste and flavours. This makes consuming mushrooms all year round possible, as products dried in this way can be stored for long periods of up to 24 months.
