Meeting the global demand for shea oil and shea butter extraction
Today, the global shea market represents an estimated value of $2.75 billion, which is set to double within the next ten years to exceed $5.5 billion by 2033. Africa produces approximately 1,760,000 metric tons (MT) of raw shea nuts a year, and historically, most of this stayed within the African continent to supply domestic demand.
Microwave assisted extraction (MAE) of butter from sheanut kernels was carried using the Doehlert’s experimental design. Factors studied were microwave heating time, temperature and solvent/solute ratio while the responses were the quantity of oil extracted and the acid number. Second order models were established to describe the influence of
Shea butter extraction technologies: Current status
Shea butter is a high– value shea nut fat used as an edible oil, antimicrobial and moisturiser in the food, pharmaceutical and cosmetic industries, respectively. The annual worldwide export of
Shea butter is a vegetable fat extracted from kernels of the shea tree. The shea tree grows in the so-called shea belt, which includes roughly 21 countries: Benin, Burkina Faso, Cameroon, Central African Republic, Chad, Ethiopia, Eritrea, Ghana, Guinea-Bissau, Ivory Coast, Mali, Niger, Nigeria, Senegal, Sierra Leone, South Sudan, Sudan, Togo, Uganda, the Democratic Republic of the Congo, Kenya
Shea butter, Wikipedia
A young woman selling shea butter in Ghana. Shea butter ( / ʃiː / shee, / ˈʃiːə / SHEE-ə, or / ʃeɪ / shay; Bambara: sìtulu ߛߌ߮ߕߎߟߎ [1]) is a fat ( triglyceride; mainly oleic acid and stearic acid) extracted from the nut of the African shea tree ( Vitellaria paradoxa ). [2] It is ivory in color when raw and commonly dyed yellow
But Ofosu (2009) asserts that shea butter extraction by the traditional method has reached 35–40% extraction efficiency. Several studies have been undertaken in order to increase shea butter extraction rate but also to improve the shea butter quality using the traditional processing conditions (Louppe et al., 1995; Hall et al., 1996).
African Shea Butter Properties Related to Common Extraction
Shea butter is an important lipid material for food, cosmetic, and pharmaceutical industries. Most of the shea butter consumed in the world comes from Africa. The extraction protocol is not standardized among all regions of production. It can be done using either traditional or improved (semi-mechanical) processes. The quality of shea butter and its composition depend on multiple factors such
The % oil yield of the shea butter obtained from Soxhlet extraction (SBSE) and cold press methods (SBCP) are 44.65% and 33.34%, respectively (Table 2) showing that shea butter obtained from solvent extraction has higher yield, but costlier as it involved the use of expensive chemical reagents, which may not be easily accessible for small scale production.
Optimization of Shea (Vitellaria paradoxa) butter quality
Extraction of shea butter. Pretreated kernels were pressed in a single step using a Komet screw oil expeller (Model: CA 59 G, 2011, Germany). The expeller was set using 4 mm restriction die and 20 rpm screw speed. In each run the kernels were warmed in air tight jar at their perspective die temperature for 30 min just before pressing.
to enhance effective extraction of the oil Extraction of Oil from Shea Nut Using Solvent Extraction Method In the experiment, 30g of 0.45mm particle size of the prepared shea nut particles was placed in a wrapped cloth (handkerchief) in place of the thimble and placed into the received portion of the soxhlet extractor. 150ml of n-hexane was poured
