Abstract
Instrumental neutron activation analysis (INAA) was to determine the nutrient status of six varieties of plantain. A total of 12 minerals were detected in both the pulp and the peel although their concentrations differed from variety to variety. Of these elements, only two (Mg and Cl) were classified, as macronutrients while seven (Cr, Zn, Se, Fe, Co, Mn, and Cu) were micronutrients essential for human life. The concentration of Cl, Mn and Cr in the edible pulp far exceeds the recommendations of the Subcommittee on Recommended Dietary Allowance (RDA). Aluminum, Br and Rb, which are neither classified as macro- nor micronutrients, were found in comparatively higher concentrations in the peel than is the pulp. The presence of seven micronutrients essential to human life in plantains makes it suitable for food, particularly in areas where micronutrient deficiencies may be prevalent.
