Processing of Shea Nuts and Production of Shea Butter

Treatment

Pretreatment (removal of unwanted materials from wild fruits) is necessary to render the nuts suitable for the oil extraction process.

De-Pulping

We de-pulp by removing the fleshy mesocarp. In order to facilitate this process, we allow the fruits to ferment by boiling or burying them. 

Drying Of Nuts & Smoking of Kernels

Sun drying for 5-10 days reduces the moisture content to about 15-30% and facilitates dehusking which is the process we employ to remove the hard shell or coat covering the endoderm containing the oil.

The drying process takes 4-5 days at a temperature of 50°C, leaving the moisture content of the kernel between 6-7% (7% moisture is needed for safe storage of up to 2 yrs). The baking process is controlled in such a way as to prevent charring of the kernel, a condition that reduces the fat content.

De-Husking

At this stage we pound using a mortar and pestle, and cracking between two stones.

Pounding & Grinding

Pounding and grinding is done in large wooden mortars, between a stone and an iron bar, or using a stone and a wooden roller. The product may be heated either during or after this process.

 

Mixing With Water, Treating, Kneading and Churning

Since the kneading is the most crucial step in determining the quality of the final product, we pay particular attention to the changes in temperature, consistency and appearance. These qualities can only be assessed correctly with experience.

Floating, Washing and Refining

We work small amounts of dough with fingers in cold water. This vigorous mixing breaks the emulsion, causing a grey, oily scum to rise. The oil is skimmed and washed repeatedly in a basin with clean water to eliminate residues. In order to clarify the butter, we melt and boil the solid fat in a pot until it is clear and bubbly. The fat is then poured into a basin where it is left to solidify.

Depending the season, the shea nuts origin and the roasting the color can change. Above three colours for same quality raw virgin shea butter.
