African insects with huge potential for nutritious diet

larve
Entomophagy- eating insects- is endorsed by the FAO as a way to address global food security challenges. Our research has demonstrated excellent nutritive potential for human diet in three insects eaten in Cameroon.

The nutritional properties of three insects consumed in Cameroon were characterized: wild or farmed Rhynchophorus phoenicis larvae, and caterpillars of Imbrasia truncata and I. epimethea. Rhynchophorus larvae are rich in lipids and also contain protein of good nutritional quality. These larvae thus make a potentially good energy supplement. Less lipid-rich but with alpha-linolenic acid as the main fatty acid, Imbrasia caterpillars are a rich source of high-quality proteins, containing all the essential amino acids. These caterpillars thus make a good option to address protein-energy undernutrition and readjust ω3 fatty acid intakes. The sorption curves put maximum water contents in the range 5-6%, making the insect flours microbiologically stable ikn storage at temperatures of up to 40°C.
