5. Harvesting and Storage

Harvesting Cocoa Beans:

Farmers use long-handled knives or big machetes to harvest the ripe cocoa pods. The pods are ripe when they turn into a deep yellow color (for most of the varieties).

They are collected and then broken up with wooden tools. The beans inside are removed by hand. The shell is discarded and the wet beans are fermented for a number of days. This step is important for the development of the flavor. For the fermentation, the beans are placed in wooden boxes on the farm.
After fermentation, the beans are carried to the villages. There, they are dried on concrete floors for 7-10 days.
The speed of drying is very important. If the beans are dried too fast, they can develop acidic flavors. This is because when dried too fast, it is possible that the cotelydons do not dry completely and only the outer shell dries. After a few days, funghi can grow on the beans.
Sun drying usually provides optimal conditions. Sun and wind combined most of the times ensure adequate drying conditions.

Storage of Cocoa Beans: 

Optimal storage conditions for cocoa beans include the following aspects:
1. The warehouse should not have cracks or holes in the walls to prevent insects from coming inside. Furthermore, they should have non-inflammable cement walls.
2.The floor level should be higher than the surrounding areas to prevent flooding.
3.The roof should be well-sealed and insulated, but not made of wood.
4.Adequate ventilation should be installed to prevent the development of molds.
5.The bags of beans shoud be stored on pallets, so that the bottom layer has air ventilation as well. The top layer of bags sould be at least 5-10cm away from the ceiling. Also to allow air ventilation.
6.The cocoa beans should be regularly inspected to prevent contaminations.
7.No other products should be stored next to the cocoa beans to avoid contamination.
8.The access to the storage area should be monitored and recorded.
