Pistachio Processing Operations
Almost all of the procedures in the pistachio processing operation are handled by machinery and through a production line. The nuts can be harvested manually or mechanically. The advantage of manual picking is that each single nut can be examined and appraised. Unsound and infested nuts are recognized and sorted out. The advantage of the mechanical harvest is the speed.Once harvest is underway the pistachios are taken off the trees around the clock and immediately processed to minimize the risk of Aflatoxin. Aflatoxin is a metabolic product of the mould fungus which develops in connection with dirt and moisture over a certain period. Taking this fact into consideration, it is absolutely important that the pistachios do not get in contact with the soil during the harvest and that long interim storage is avoided.
