PURPOSE:To prevent mushrooms from lowering in freshness and their ring color from changing to brown in transit and on sale by a method wherein the mushrooms are placed in a lidless container and wrapped in a specific thin transparent film and a specific surfactant is provided on at least the interface between the film and the mushrooms. CONSTITUTION:A thin transparent film 3 for use in covering the mushrooms placed in a lidless container 1 has a steam permeating rate of 20-500g/m<2>.24 hours.(38 deg.C) and an oxygen gas permeating rate of 2000-30000ml/m<2>.24 hours.atm (23 deg.C).
