Assessment of the Nutritional Value of Winged Termites ( Macrotermes b ellicosus ) in the City of Man

This study, conducted on winged termites ( Macrotermes bellicosus ) collected in the Man region, assessed their mineral, lipid and protein composition in order to highlight their nutritional value. The results showed a high content of essential minerals, notably iron, calcium, potassium, magnesium and phosphorus, confirming the nutritional potential of these insects in combating dietary deficiencies and iron-deficiency anaemia. Trace elements such as zinc, copper, manganese and iodine were also detected in low concentrations but remain important for the body’s physiological functions. Lipid analysis of the extracted oil revealed a predominance of monounsaturated and saturated fatty acids, with a notable presence of polyunsaturated fatty acids and omega-3s, which are beneficial for cardiovascular health and neurological development. Analysis of the amino acid profile highlighted the presence of several essential amino acids, notably lysine, threonine, leucine and tryptophan, demonstrating the high biological value of the proteins in winged termites. These results confirm that Macrotermes bellicosus constitutes an alternative food resource of high nutritional value that can contribute to dietary diversification and improved food security for populations in West Africa, particularly in areas affected by malnutrition.
