In Benin Republic, there are five different known shea parks. The dedicated various studies to the
characterization of nuts and kernels in Benin, and in the sub-region, are often limited to the samples taken
from only one zone and did not take into account the variability of the production zones. This study aimed at
assessing the physical properties of shea kernels collected in four shea parks of Benin. Sizes (length, width,
thickness), one-thousand nuts weight, the true and bulk volumes, sphericity, porosity and the true and bulk
densities, have been determined on shea kernels from each park using appropriate methodology. The results
showed that average moisture content of the shea kernels was 7.55±1.23% (wb). The parks of Kandi and Savè
displayed the smallest shea kernels while those from Parakou and Bembèrèkè, showed the biggest. Sphericity
of shea kernels turns around 0.72 whereas their porosity ranges from 41.59 to 43.24% and the weight of onethousand
kernels ranges from 3.98 to 4.40 kg. The true and bulk volumes of one-thousand kernels vary from
3.88 to 4.37 dm3 and 6.64 to 7.70 dm3 respectively. The true and bulk densities fluctuate from 1,007.51 to
1,024.24 kg/m3 and 571.77 to 598.12 kg/m3 respectively. These results call for the development of appropriate
equipment for shea processing in Benin. |
