🌰 Composition of the Shea Nut Kernel

The kernel of the shea nut is the vital part used for shea butter extraction and contains:

Fatty acids:

Stearic acid (20%–50%) – gives shea butter its solidity

Oleic acid (40%–60%) – gives it creaminess and moisturizing properties

Linoleic acid and palmitic acid in smaller quantities

Vitamins: A, E, F (natural antioxidants)

Other Components:

Triterpenes (anti-inflammatory)

Catechins (antioxidants)

Allantoin (skin-soothing agent)

Phytosterols (helps with healing and regeneration)

🌾 Fruit and Nut Development

The shea tree bears green, plum-like fruits that ripen during the rainy season (May to August).

Each fruit contains:

Sweet edible pulp

One large nut enclosed in a thin shell

The nut is harvested by hand, usually by rural women, after the pulp is consumed or removed.

🧈 Processing Into Shea Butter

Traditional processing of the nut into shea butter includes:

1. Harvesting the ripe fruits from the wild.

2. Pulp removal to extract the nut.

3. Boiling or sun-drying the nuts to reduce moisture.

4. Shelling the nut to access the inner kernel.

5. Roasting the kernels to enhance oil extraction.

6. Grinding and kneading into a paste.

7. Adding water and stirring to release the oils.

8. Collecting and boiling the oil to form the final shea butter.
