摘要: Termites are widely used as a food resource, particularly in Africa and Asia. Markets for insects also expanding worldwide. To inform the development of insect-based foods, we analysed selected minerals (Fe-Mn-Zn-Cu-Mg) wild-harvested commercially available termites. Mineral values were compared to insects. Alate termites, genera Macrotermes Odontotermes, showed remarkably high manganese (Mn) content (292-515 mg/100 gdw), roughly 50-100 times concentrations detected other Other mineral elements occur at moderate all examined. On further examination, Mn is located primarily abdomens subhyalinus; with scanning electron microscopy revealing small spherical structures highly enriched Mn. We identify fungus comb, subhyanus, potential biological source concentrations. Consuming even quantities termite alates could exceed current upper recommended intakes both adults children. Given widespread use termites food, better understanding sources, distribution bio-availability these needed.
