highly instable in terms of spoilage (Ariahu, Kaze, &
Achem, 2006). EMC of the mushroom increased with
water activity at selected temperatures regardless of drying
method used, following the form of a Type II isotherm
according to the BET classification. This may be due to the
fact that vapor pressure of water present in foods increases
with that of surroundings (Shivhare, Arora, Ahmed, &
Raghavan, 2004).
