Different methods based on washing to extend storage time and
reduce the contamination levels on mushrooms have been developed
(Pramod, Fernanda, Anthony, & Aurelie, 2008; Yuk, Yoo, Yoon,
Marshall, & Oh, 2007). However, some washing treatments would
result in tissue injury of mushrooms because of the mechanical
damage and increased water uptake during the washing operations.
For example, mushrooms washed with hypochlorite at
50 ppm generally deteriorate more rapidly than unwashed due to
mechanical damage and water uptake, which in turn, leads to
subsequent bruising and increased microbial growth Among the washing methods, it is reported that
mushrooms washed with H2O2 were free of adhering compost or
casing residues, less subject to brown blotch than conventionally
