Shea nut meal is obtained after fat extraction from shea nuts produced in West Africa. Two experiments compared the ME of different shea nut meal samples. The objective of the first experiment was to estimate the TME(n) of 2 expeller shea nut meal samples and a single nonindustrial shea nut meal sample using a precision-fed broiler assay. The second objective was to compare the nutrient composition of 6 collected shea nut meal samples (i.e., 4 expeller, 2 nonindustrial) as well as 2 defatted samples (1 expeller, 1 nonindustrial) and to examine the differences in AME between the samples. The 8 shea nut meal samples were fed at 3 dietary levels (0, 2, 4%) in a nutritionally complete basal diet to 180 Ross male broiler chicks (12 to 20 d) in an AME assay. The mean TME(n) (3,577 kcal/kg of DM) of expeller samples was higher (P<0.001) than TME(n) (3,017 kcal/kg of DM) of the nonindustrial sample. The dietary level of shea nut meal had a significant (P<0.01) effect on AME with the 4% level tending to give a lower AME than the 0 or 2% levels. However, increasing levels of defatted shea nut meals from 2 to 4% had no effect on AME of the diets. It was concluded that the available energy concentrations in the shea nut meal samples were low relative to their nutrient compositions and variable due to the content and nature of the residual fat. The variation observed among samples indicates that industrial expeller shea nut meal samples are preferable to nonindustrial meals for use in poultry rations. The nutritional quality of shea nut meal still needs improvement to allow it to be a valuable feed ingredient.

Background: The shea tree is a well-known carbon sink in Africa that requires a sustainable conservation of its gene pool. However, the genetic structure of its population is not well studied, especially in Côte d'Ivoire. In this study, 333 superior shea tree genotypes conserved in situ in Côte d'Ivoire were collected and genotyped with the aim of investigating its genetic diversity and population structure to facilitate suitable conservation and support future breeding efforts to adapt to climate change effects.

Solvent extraction is the most efficient technique for extracting oils of higher quality for prospective industrial and commercial applications. Here, we present a protocol for extracting oil from Ghana shea nuts using this technique. We describe steps for drying and milling kernels; oil extraction, including the kinetic and thermodynamic processes; and filtration.

Though little research has been done, shea nut oil (Shea Butter), is a promising shea product with great potential for use in industrial shea product manufacture. To assess the oil obtained from the shea nuts for personal, commercial, and industrial use, this study focuses on the extraction process, the optimal solvent for extraction, thermodynamics and kinetic studies, and characterization of the oil. Using different solvents as well as extraction temperatures and times, the oil was extracted using the solvent extraction method.

The Expert Panel for Cosmetic Ingredient Safety (Panel) assessed the safety of 13 (shea)-derived ingredients, which are most frequently reported to function in cosmetics as skin and hair conditioning agents. The Panel reviewed the available data to determine the safety of these ingredients. Because final product formulations may contain multiple botanicals, each containing similar constituents of concern, formulators are advised to be aware of these constituents and to avoid reaching levels that may be hazardous to consumers.

In this paper, TOPSIS (Technique for order of Preference by Similarity to Ideal Solution) COPRAS (Complex Proportional Assessment) and VIKOR (Multi-criteria Optimisation and Compromise Solution) were used to select optimal crop residues for sustainable gasification in Ghana among thirteen residue types. The Analytical Hierarchy Process (AHP) was used as weighting criteria for the three Multi-Criteria Decision-Making (MCDM) techniques.
