Understanding the Shea Tree
Understanding the Shea Tree
The shea tree (Vitellaria paradoxa) grows 10-15 meters tall with large, sturdy leaves, thriving in the savanna zone. Its fruit resembles a small coconut with dark green skin. A single tree can bear fruit for 200 years.

Waiting for the Fruiting Season
Waiting for the Fruiting Season
Shea fruits ripen between June and September (Okudu-Owewe) in southern Nigeria. Ripe fruit will fall from the tree on its own. Do not pick fruit from the tree — only fallen fruit is properly ripe.

Collecting Fallen Fruit
Collecting Fallen Fruit
Early in the morning, follow the fallen fruit under shea trees. Collect them into baskets or bags. A single tree can yield 15-20 kg of fruit per year.

Removing the Fruit Pulp
Removing the Fruit Pulp
Shea fruit has a green outer skin and sweet pulp inside. Remove the pulp from the shea nut. The shea fruit pulp is edible — it is sweet and contains vitamin C. Children often eat it.

Boiling the Shea Nuts
Boiling the Shea Nuts
Place the shea nuts in boiling water for 20-30 minutes. Boiling kills organisms that could cause the nuts to sprout, and softens the shell for cracking.

Cracking the Nut Shells
Cracking the Nut Shells
The shea nut shell is hard. Use a stone or mallet to crack the shells one by one. Be careful not to crush the kernel inside — the kernel is what we need. Work carefully and methodically.

Extracting the Kernels from the Shells
Extracting the Kernels from the Shells
Remove the white-to-brown kernel from the cracked shell. A single shea kernel weighs approximately 5-8 grams. Set the shells aside — they can be used as fuel for cooking.

Inspecting Kernels for Quality
Inspecting Kernels for Quality
A good kernel has a white-cream to light brown color. Kernels that are black or have a bad smell are spoiled — discard them. Cut a kernel in half — the inside should be cream-colored.

Spreading Kernels in the Sun to Dry
Spread kernels on a mat or rack in the sun. Do not pile them on top of each other. Turn them two to three times daily to ensure even drying on all sides.

Drying for 5-7 Days
Drying for 5-7 Days
Kernels need 5-7 days to dry properly in the sun. At night or during rain, collect them into a dry space. Properly dried kernels should have no more than 7% moisture content.

Testing the Dried Kernels
Testing the Dried Kernels
Properly dried kernels are hard and make a sound when they hit the ground. If you break one open, the inside should be dry and firm — not moist or soft. Their weight will have reduced by approximately three-quarters.

Packing the Dried Kernels into Bags
Packing the Dried Kernels into Bags
Place dried kernels into breathable burlap or jute bags. Do not use plastic bags — they trap moisture and cause kernels to spoil. Label each bag with contents and drying date.

Storing Kernels in a Dry Place
Place bags in a dry, cool, well-ventilated storage area. Elevate bags off the ground on pallets or raised platforms. Properly dried shea kernels can last up to 12 months without spoiling.
