Mushroom harvesting is the manual or mechanical collection of fruiting bodies at the optimal maturity stage, where timing and handling directly determine grade, appearance, moisture level and shelf life for fresh, frozen and dried trade.
In trade practice
For cultivated Agaricus species, harvesting at the closed-button stage before the veil breaks is standard practice for premium grades; open or broken caps are typically directed to sliced or processed formats. Harvesters use gloves and shallow trays to minimise bruising, which causes rapid browning. Rapid pre-cooling after picking is critical to slow respiration and microbial growth. For wild species destined for drying, maturity at harvest also affects the final moisture content and the ratio of usable to rejected material after cleaning.
In a specification
A mushroom supply specification states the required maturity stage at harvest, maximum cap diameter, permitted veil status and the post-harvest cooling time or temperature target before processing begins.
