Processing & Marketing of Frozen Mushrooms

Processing of Frozen Mushrooms

The greatest percentage of mushrooms these days are frozen. After a thorough cleaning, the product is graded into different sizes according to the head diameter of the mushrooms.

  1. Mushrooms with head diameter of between 50 and 100 millimeters are frozen whole.
  2. Mushrooms with a head diameter greater than 100 millimeters, mature but still firm, might be cut in halves, quarters, sections or sliced before freezing.
  3. Mushrooms which are soft and fully mature are cleaned of the dark green section under the head and diced into cubes of varying sizes according to customer demand and then frozen.

After freezing the mushrooms are packed into food compatible plastic bags and into cardboard boxes, weighed, sealed and palletized. The full pallets are stored at temperatures of -25º Celsius ready for transportation by refrigerated truck to seaport from where they are loaded into refeer containers for final transportation to the export markets. Once frozen, the mushrooms are maintained in the cold chain at -25º Celsius all the way to final consumption.
