The proximate analysis of two edible insects in Ijebu division
(South Western Nigeria) was analyzed. This was carried out to
clarify the nutritional elements evident in the two edible
species. The samples were collected through water trap and by
handpicking respectively with a view of adopting the method of
the Association of Official Analytical Chemists for the
proximate analysis. Proximate analysis of these two revealed
that Rhynchophorus phoenicis (larva) and Macrotermes
bellicosus (winged reproductive) were very rich source of
protein (63.14%, 47.08%) respectively. Fat level (8.19%, 22.45%)
varied between both species both with very low carbohydrate
(1.65%, 1.82%). They were rich sources of crude fibre (21.99%,
15.82%) and ash (37.34%, 31.83%). Both insects are sources of
vitamin A, B1, B2, B3, B5, B7, B9 and B12, C, D, E and K. The
minerals study in R. phoenicis (larva) and M.
bellicosus (winged reproductive) revealed that Manganese
(2244.90mg/kg, 75.85mg/kg), Magnesium (2844.90mg/kg,
603.00mg/kg), Potassium (5032.50mg/kg, 5063.00mg/kg), Iron
(269.55mg/kg, 353.30mg/kg) were present with low Calcium level
(1.96mg/kg, 1.54mg/kg). In view of this, the two edible insect
species are rich sources of protein, vitamins and minerals.
