ABSTRACT

Introduction: The young shoots of roan are produced and consumed in Dimbokro, in central Côte d'Ivoire. However, they are delicately preserved and their nutritional value remains little explored. In this study, the product was sun and oven dried at 40°C and 50°C and then ground to produce flours with respective codes FS, F40 and F50. Context: In recent years, illegal gold mining has become established with unfortunate consequences for the ecosystem and agrosystems practised in the region. Also, farmers use chemicals (pesticides, fertilisers) in their plantations. Objectives: The general objective of this work is to evaluate the mineral composition of young shoot flours produced according to three drying methods in order to perceive the impact of illegal gold mining and agricultural practices in the Dimbokro area on the quality of the food produced. Methods: The samples were then subjected to analysis of their mineral composition by air-acetylene flame atomic absorption spectrometry using an AAS 20- Type VARIAN device. Results: This analysis revealed the significant presence of minerals essential to health such as Sodium (0.044 to 0.115 ppm), Phosphorus (0.019 to 0.021 ppm), Potassium (0.068 to 0.181 ppm), Calcium (0.110 to 0.122 ppm), Iron (0.043 to 0.069 ppm). However, this study also showed the presence of heavy metals such as lead (0.012 to 0.037 ppm), Arsenic (0.043 to 0.056 ppm), Mercury (0.076 to 0.142 ppm). Conclusion: We found that only mercury is the heavy metal with a hazard quotient greater than 1, which constitutes a significant health risk following the consumption of young shoots. The agro-system of young shoots of roan production and illegal gold panning in the study area should be regulated to avoid the concentration of heavy metals in consumer products.
