Title: Modified Atmosphere Packaging of Mushrooms – Review and Recent Developments
Author: K.S. Burton

Abstract:

Good and consistent mushroom quality is essential for high value sales and is the consequence of growing technique, picking and post-harvest management. Low quality mushrooms resulting from poor growing techniques and picking practices can be selected out but thereafter quality is dependent on good post-harvest practices. Modified Atmosphere Packaging (MAP) of mushrooms has been shown successfully to delay senescence and maintain quality after harvest in an experimental system. For MAP to be commercially viable, the following factors must be assessed: (1) Optimal and effective gas concentrations (carbon dioxide and oxygen) for delaying mushroom senescence. (2) Interaction of MAP with cooling. (3) Presence or absence of free water in packs. (4) The possibility of anaerobiosis for example by over-labelling the film. (5) The cost-effectiveness of MAP by enhancing storage-life. Two MAP systems for mushrooms have been tested at HRI-Littlehampton. Data on the above factors are presented and discussed in relation to the mechanism of action of modified atmosphere packaging.
