Parkia biglobosa is a non-wood forest product whose resources are used in food and pharmacopoeia. The pulp has interesting nutritional qualities. African locust bean fruits harvested in Senegal are characterised by low moisture (9.78% to 12.31%), which is crucial for long storage. The pulp is slightly acidic (pH = 4.84 to 5.16). It is also very rich in sugar, with a minimum concentration of 30.8g/100g, and is mainly made up of reducing sugars. Carotenoids are abundant in the pulp (on average 16.75 mg/100 g) and β -carotene is the main carotenoid. As for minerals, K and Mg are the most abundant, with average concentrations of 451.33 mg/100 g and 300.67 mg/100 g respectively. In addition, heavy metals such as arsenic, lead and cadmium are below the detection threshold (<0.002 mg/100 g) and are present in the pulp at a concentration below the standard set by the Codex Alimentarius. The organic acid profile was also determined, showing that citric acid (average 1131.88 mg/100 g) is the predominant organic acid in the pulp. Principal component analysis (PCA) revealed that the pulp of Parkia fruits harvested in Senegal was homogeneous in terms of physico-chemical and biochemical characteristics, despite a few differences.
