Effects of Extraction Methods on the Yield and Quality

Shea butter oil was studied with aim of determining the most suitable method for use by rural processors based on oil yield and quality characteristics. This was done by comparing results of physical, chemical and sensory properties of oil extracted by Solvent Extraction Method (SEM) and Traditional Extraction Method (TEM). Results showed that ...

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 ...

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.

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 nuts are mainly exported as smoked kernels. The kernels will be further dried before any additional processing is carried out. Shea nut butter Traditionally wet processing by hand is a slow and laborious process that uses large quantities of wood as fuel for roasting. Nuts are shelled by hand by being pounded individually using

Oil extraction from sheanut (Vitellaria paradoxa Gaertn C.F

Today the shea tree is the second most important oil crop in Africa after the palm nut tree but its potentials is not fully exploited. The use of microwave extraction technology has the potential of producing volumes good quality oil within short production cycles and therefore should be evaluated for each oilseed to determine optimum ...

  • 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.
  • 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.
  • Is shea butter oil Rancid?
  • The acid value for shea butter oil extracted by SEM (1.20±0.13) is higher than that of TEM (0.50±0.06), indicating greater susceptibility to rancidity. However, the acid value for TEM stayed below the accepted threshold of 1% for edible oils.
  • What does a shea fruit consist of?
  • A shea fruit consists of a kernel (embryo), which contains about 60% edible fat, a green epicarp, a fleshy mesocarp (pulp), and a shell cover (endocarp).
