Fresh oyster keeps 24-48 hours at room temperature, so plan the sale before the pick. The folder's method: spread the mushrooms on a cloth for about two hours so surface water dries, then pack in perforated polythene; in a refrigerator they hold 2-4 days.
The DMR post-harvest bulletin specifies polythene under 100 gauge with holes giving about 5 per cent vent area. TNAU packs 200 g per bag for retail.
