| Abstract |
Nutritional potentials of edible larvae of Longhorned beetle (Apomecyna parumpunctata) was investigated. Proximate composition of the edible larvae had protein (16.24%), fat (13.26%) and high moisture content (60.45%) with average energy of 212.32kcal/100g. The larvae had low amounts of three essential minerals (calcium, magnesium and sodium) ranging between 4.7-16mg/100m/Dm and lower amounts of potassium and phosphorus (1.52mg/100g/Dm). Fatty acid composition of the larvae showed highest amounts of monounsaturated fatty acids (MUFA) oleic (50.26%), nervonic (2.57%, erucic (2.57%) and palmitoleic (1.40%); followed by saturated fatty acids (SFA) palmitic (24.60%), behenic (2.03% and myristic (1.83%). There were low amounts of polyunsaturated fatty acids (PUFA) which are good for health of the heart; linoleic (12.28%) known as Omega 6 – acid; linolennic (0.21%), docosahexaenoic (0.21%) and eicosadienoic (0.25%) which are known as Omega 3–acids. The fats obtained occasionally by the consumption of roasted larvae are relatively good for health because it had PS ratio of 0.43 which has lower risk for heart disorders than the common saturated oils. |
