Proximate and Mineral Composition of Edible Alate Termites (Macrotermes subhyalinus)(Rambur) in Nasarawa State, Nigeria


Abstract

This study was aimed at evaluating the proximate and mineral composition of Macrotermes subhyalinus, an edible termite species, with a view to revealing any possibility of its use as a base for the formulation of new food/feed products as a possible means of combating malnutrition. A minimum size of 2 kg of adult winged termites was collected, oven-dried at 40°C to a constant weight and analysed according to official methods of analysis recommended by the Association of Official and Analytical Chemists (AOAC). The analysis revealed high protein (3.5 - 5.0 + 0.12%), fat (33.3 + 0.29%) and carbohydrate (24.1 + 0.12%) contents, yielding a calculated energy value of 560.1 kcal/100 g. Mineral analysis showed significant levels of 361.41 mg/g and 230.60 mg/g for phosphorus and calcium, respectively. The low moisture content (3.10 ± 0.02%) enhanced self-stability. These results indicated that this delicacy is a potentially rich source of nutrients that may be necessary for combating protein-related disease conditions prevalent in developing countries of the world.
