ABSTRACT:

Studies conducted on chemical composition of bean weevil (Acanthoscelides obtectus) revealed that a mg/100g dry matter sample of the weevil contains 34.14 ± 0.02% moisture, 38.94 ± 0.01% crude protein, 34.07 ± 0.03% crude fat, 12.00 ± 0.01% crude fibre, 8.00 ± 0.01% ash and 36.99 ± 0.01% carbohydrate, the results of the mineral composition showed that mg/100g dry water sample of bean weevil contains Ca (3.30 ± 0.01), Mg (1.0 ± 0.01), Na (0.01 ± 0.02), K (0.31 ± 0.02), P (0.022 ± 0.02), Zn (2.09 ± 0.02), Mn (1.60 ± 0.02), Cu (1.15 ± 0.01) and Fe (7.92 ± 0.01). The toxicants content of a mg/100g of the sample were 5.28 ± 0.01, 2.64 ± 0.01, 4.96 ± 0.01 and 3.30 ± 0.01 for total oxalate, HCN, tannins and phytate respectively. Hence bean weevil contains less amount of toxicants and high amount of vital nutrients required for healthy living.
