Physical, chemical, and nutritional characterization of false Kinkeliba seeds (Senna occidentalis L.) from Korhogo (Côte d'Ivoire)

False kinkeliba is a wild plant with numerous pharmacological properties, whose seeds can be processed into a coffee substitute. The aim of this study was to promote Ivorian agricultural resources by characterizing Senna occidentalis L. seeds. To this end, the physical, chemical, and nutritional parameters of the seeds were determined using conventional methods. Results showed that Senna seeds were rich in minerals such as calcium (4110.72 mg/kg), potassium (953.657 mg/kg), magnesium (286.538 mg/kg), phosphorus (209.902 mg/kg), sodium (197.701 mg/kg), zinc (56.252 mg/kg), and iron (12.236 mg/kg). The macronutrients present were total carbohydrates (79.57%), crude fiber (23.11 ± 0.68%), lipids (3.28 ± 0.09%), and proteins (3.09 ± 0.21%). Seeds had an energy value of 360.16 kcal, an ash content of (7.31 ± 0.04%), titratable acidity of 7.14 ± 0.12 g/100 mL with a slightly acidic pH (6.20 ± 0.005), water content of 6.75 ± 0.2%, and dry matter content of 93.25 ± 0.2%. The sizes were 11.06 ± 1.64 cm for the pods and 0.3 ± 0.1 cm for the seeds. Given the high nutrient content of the seeds, consuming them could be beneficial for the body.
