Introduction: The need for alternative protein and essential micronutrients sources for adequate complementary foods is urgent. Dried Marcrotermes bellicosus was reported to be a good source of dietary protein fat and micronutrients. This study investigated the fatty acid profile protein and essential micronutrient bioavailability in M. bellicosus using albino rats. Methods: M. bellicosus was collected around the Alegongo area Akobo Ibadan Nigeria during their swarming flights roasted at 105C for fifteen min dewinged and winnowed. The roasted sample was analysed for proximate minerals and antinutrients using standard methods of the AOAC International. Fatty acid profile was determined using a gas-liquid chromatographic method whilst protein and essential minerals bioavailability were determined using weanling albino rats. Results: Roasted M. bellicosus contained 31.8 g protein 16.4 g fat 1.3 g ash 46.5 g carbohydrates 361.13 mg potassium 227.50 mg calcium 361.30 mg phosphorus 15.03 mg zinc 52.30 linolenic acid 24.91 linoleic acid 5.97 oleic acid and yielded 460.8 kcal gross energy/100g sample. The mean weight gain in the experimental diet group (23.176.71) was significantly higher than that of the control diet group (16.836.71) and the basal diet group (-19.509.03). The basal diet group had the least value for all serum micronutrient levels whilst the experimental diet group had the highest. Conclusion: M. bellicosus protein supported rat growth at a 15 inclusion level. The calcium iron zinc and vitamin A in M. bellicosus were bioavailable in rats. M. Bellicosus could be a potential novel food for humans.

Abstract

Introduction: The need for alternative protein and essential micronutrients sources for adequate complementary foods is urgent. Dried Marcrotermes bellicosus was reported to be a good source of dietary protein fat and micronutrients. This study investigated the fatty acid profile protein and essential micronutrient bioavailability in M. bellicosus using albino rats. Methods: M. bellicosus was collected around the Alegongo area Akobo Ibadan Nigeria during their swarming flights roasted at 105C for fifteen min dewinged and winnowed. The roasted sample was analysed for proximate minerals and antinutrients using standard methods of the AOAC International. Fatty acid profile was determined using a gas-liquid chromatographic method whilst protein and essential minerals bioavailability were determined using weanling albino rats. Results: Roasted M. bellicosus contained 31.8 g protein 16.4 g fat 1.3 g ash 46.5 g carbohydrates 361.13 mg potassium 227.50 mg calcium 361.30 mg phosphorus 15.03 mg zinc 52.30 linolenic acid 24.91 linoleic acid 5.97 oleic acid and yielded 460.8 kcal gross energy/100g sample. The mean weight gain in the experimental diet group (23.176.71) was significantly higher than that of the control diet group (16.836.71) and the basal diet group (-19.509.03).
