The Process of Harvesting Cashew Nuts
The Harvesting Process
Harvesting cashew nuts is a labor-intensive process that requires careful timing and technique. The cashew tree produces both the nut and the cashew apple, which is a fleshy fruit that grows at the end of the nut. The harvesting season typically occurs during the dry months when the nuts are ripe and have fallen from the tree.
Farmers often begin by collecting fallen nuts from the ground, which can be a time-consuming task as they must sift through leaves and debris to find the mature nuts. It is crucial to harvest at the right time; if left too long, the nuts can become spoiled or infested with pests.
Removing the Outer Shell
Once collected, the nuts undergo a series of steps before they are ready for consumption. The first step involves removing the outer shell, which contains a toxic resin known as urushiol. This resin can cause skin irritation, so workers must take precautions when handling raw cashew nuts.
Roasting and Processing
After shelling, the nuts are roasted to eliminate any remaining toxins and enhance their flavor. This roasting process also makes it easier to remove the inner skin, resulting in the familiar white or lightly colored cashew nut that consumers recognize.
Quality and Safety Concerns
The entire process requires skill and attention to detail, as improper handling can lead to loss of quality or safety concerns.
