Several varieties of Burkina Faso are cultivated, but their nutritional composition remains poorly studied. This study aims to evaluate the physicochemical and nutritional properties of four sesame varieties ( A Kilom , Wollega , Pakre-saaya , Bo nognora ) available in Burkina Faso, whole and after hulling, produced in Burkina Faso. Color parameters were evaluated according to the CIE Lab* system, and physicochemical and nutritional parameters according to standard methods. The results revealed that hulling significantly influences seed color, with an increase in lightness values (L*) and a reduction in chromatic components (a*, b*). The A Kilom variety that was black in color, the other varieties were white. The results showed that whole seeds have significantly higher mineral contents. On the other hand, hulled seeds revealed a higher lipid and energy content. Significant variations were also observed between the different varieties, highlighting the influence of genotype on nutritional composition. The weight of 1000 grains varied from 1.29 g to 1.32 g. The percentage of moisture and ash ranged from 2.30 ± 0.09 to 3.95 ± 0.01% and 2.33 ± 0.02 to 6.90 ± 0.02%, respectively, and that of fat 41.80 ± 7.07 to 63.86 ± 1.41%, while the protein content ranged from 9.35 ± 7.78 to 20.15 ± 1.41%. Carbohydrate content ranged from 3.78 ± 7.92 to 10.61 ± 1.63%, energy value 2145.69 ± 16.07 to 3657.05 ± 7.07 Kj/100g. The contents of calcium, potassium, magnesium, zinc and iron ranged from 92.66 ± 7.07 to 594.81 ± 7.07 mg/100g, 203.57 ± 7.07 to 467.55 ± 7.07 mg/100g, 163.54 ± 7.07 mg/100g to 265.38 ± 7.07 mg/100g, 3.71 ± 7.07 to 4.84 ± 7.07 mg/100g and 3.25 ± 0.00 to 10.38 ± 7.07mg/100g, respectively. This study helps to better guide the choice of varieties according to food or industrial uses, and highlights the interest of sesame as a source of essential nutrients in diets.
