showed the best performance in terms of weight and containing minimum
moisture. Total drying time of D
was comparatively lower than other drying
methods. Though D

took the shortest time for drying it also reduced the quality of
mushroom. Different drying methods also influenced the colour of mushroom. For
M
the best colour: upper pileus- tan, lower pileus – corn silk and stipe – corn silk
/wheat was found in D

. For M
the best colour: upper pileus – saddle brown, lower
pileus – moccasin and stipe –tan was obtained from D

and D

. For M
the best
colour: upper pileus and stipe –wheat colour, lower pileus –corn silk was found under
D

and D
. Considering the total drying time, weight loss efficiency and colour,
D

appeared to be recommendable for oyster, shiitake and white milky mushroom.
However D

may also be used for drying of mushroom.
