Abstract

Determination of the proximate, nutritionally valuable minerals and anti-nutrient compositions in larvae of Cirina forda (W) showed that they contained high levels of protein, (55.50%±1.20%) with ash, moisture, fat, and carbohydrate levels being (10.26%±0.01%), (10.85%±0.38%), (4.68%±0.01%) and (18.70%±0.84%) respectively. Fibre was not detected. Protein solubility was higher in alkaline media than in acidic media while the isoelectric points were pH 4, 6 and 9 indicating that C. forda may be useful in food formulations involving foods like meat products. Phosphorus had the highest value of (215.54±0.21) mg/100 g while manganese had the lowest value of (1.14±0.10) mg/100 g. Copper, Co, Pb, Cr and Ni were not available. Water absorption capacity was (300%±0.15%), oil absorption capacity was (358.44%±0.21%) and foaming stability was (3%±0.00%). The results of anti-nutritional analysis revealed that oxalate and phytic acid contents were (4.11±0.05) mg/100 g and (1.02±0.00) mg/100 g respectively and that these values fell within nutritionally accepted values. Tannin was not detected in C. forda. C. forda, a rich source of animal nutrients, usable in human diets and animal feeds formulations.
