A Complete Guide to Shea Oil and Shea Butter Extraction
The shea tree provides a vital source of income for millions of indigenous women who collect fallen fruit from the wild trees. Although it represents a smaller market (in terms of volume) compared to other commodity oilseeds and nuts, shea’s enduring popularity and irreplaceable benefits are fueling its growth trajectory over the coming years.
Therefore, this study was to extract and characterise oil derived from the Ghana Shea Nut crop. A solvent extraction method was applied for the extraction of the oil at different extraction temperatures and times. Kinetic and thermodynamic models were employed to the experimental data after the extraction was conducted at various temperatures.
Oil extraction from sheanut (Vitellaria paradoxa Gaertn C.F
The various extraction methods produced distinguishable physical changes in the shea nut kernels. For example, the samples after extraction were powdery in nature compared to the untreated samples while the MAE sample produced a visually finer powder compared to that obtained from the soxhlet method.
The protocol below describes the step-by-step approach to extracting oil from Ghana Shea nut kernels using the solvent extraction technique. However, we have also used this protocol in other related works to extract oil from cocoa beans, 2 moringa seeds, 3 and cashew nuts. 4
Effects of Extraction Methods on the Yield and Quality
Effects of Extraction Methods on the Yield and Quality Characteristics of Oils from Shea Nut Author: Julius K. Ikya, Lilly N. Umenger and Ayangealumun Iorbee Subject: Journal of Food Resource Science Keywords: shea nut oil extraction methods, shea nut characteristics, shea nut physio-chemical quality, shea nut sensory quality, Shea nut oil yield
Shea nut is the fruit of African shea tree. Like avocado, shea nut has delicious flesh. The fat contained in the kernel of shea nut is shea butter, which takes up about 40% ~ 55%. Each mature shea tree produces only 15 to 20 kilograms of shea per year, which can only survive on the African continent due to climatic and plantation reasons.
Protocol for extracting oil from Ghana shea nuts using
Obtain well processed shea nut kernels to be used for the extraction of the oil. Note: The kernels should be separated from the nuts and should be fr ee from impurities and contaminants.
A similar observation was reported by [24] for the extraction of oil from shea butter using traditional extraction methods (hot water) and solvent extraction using n-hexane, whereby n-hexane ...
- How are shea kernels processed?
- Shea kernels are processed to obtain shea oil, which when solidified forms shea butter. The kernels are processed using methods such as solvent extraction. ( Coulibaly et al ., 2009 )
- Is solvent extraction method better than traditional extraction method?
- The solvent method yields a higher percentage of oil and exhibits better TBA, saponification, and iodine values compared to the traditional method of extraction. However, it lacks in overall sensory acceptability, while the traditional method scores higher in this regard.
- What is the difference between solvent extraction method (SEM) and TEM?
- Results showed that Solvent Extraction Method (SEM) had a higher yield of 47.5% (39.3% greater) than Traditional Extraction Method (TEM) with a yield of 34.1%. The smoke point was the same for both methods: 233°C. This was done by comparing results of physical, chemical and sensory properties of oil extracted by SEM and TEM.
- Is solvent method of extraction more viable than TEM?
- The study showed that the solvent method of extraction is more viable in terms of oil yield percentage and other studied quality parameters. However, it lacks in overall sensory acceptability compared to TEM, which scored higher in terms of general sensory attributes. Further studies are recommended on the sensory acceptability of the SEM.
- Why does Shea butter oil have a low iodine value?
- Shea butter oil has a low iodine value because it is rich in saturated fatty acids, which ensures stability against oxidation and rancidification of foods prepared with the oil ( Goh, 1994 ). The passage also mentions that extraction method affects sensory parameters of texture, appearance, odour/aroma, and general acceptability.
- Is shea butter oil a good vegetable oil source?
- Shea butter oil extracted by both TEM and SEM methods is capable of serving as a high yielding commercially rich source of vegetable oil.\nPeroxide Value (PV) obtained for Shea butter oil extracted by TEM was lower than that of SEM, but both methods have acceptable PV.
