Dehydration is one of the important preservation methods
employed for storage of mushroom and dehydrated
mushrooms are valuable ingredients in a variety of sauces
and soups. As mushrooms are very sensitive to temperature,
choosing the right drying method can be the key for
a successful operation. Mushroom growers continue to
dry mushroom under sun, which yields unhygienic and
poor quality product. The conventional hot-air drying of
mushrooms normally involves thermal and/or chemical
pretreatment and drying at temperature maintained
between 50 and 70 C. Due to long drying time and overheating
of surface during hot-air drying, the problems of
darkening in colour, loss in flavour and decrease in rehydration
ability occur. Freeze drying produces a high quality
product, but being an expensive process, its application for
mushroom drying is limited. Vacuum drying is another
