Abstract

Recipe of African palm weevil larvae (APWL) (Rhynchophorus phoenicis) was processed with common ingredients (vegetable oil, onion, pepper, salt, maggi, tomatoes and little quantity of dried crayfish), was used as a filler to produce a novel snack called "Rhyncho-Roll” (RR). The nutritional value of Ryncho-Roll was determined and compared with a commonly consumed snack called Gala (GL). Proximate composition of Rhyncho-roll and Gala revealed higher content of fat for Rhynocho-roll (55.90%:6.55%), protein (7.8%:6.55%), ash (5.75:4.15%) and moisture (18.30%:16.65%) respectively. Gala was higher than Rhyncho -roll in carbohydrate (42.64%:7.87%) only. Total energy value of Rhycho-Roll was 604.086kcal/100g which was more than twice the total energy value of Gala (270.205Kcal/100g). Mineral composition of Rhynco- roll and Gala showed that both snacks possessed almost equal amounts of Iron (7.1:7.4mg/100g), sodium (208:209mg/100g), potassium (1.152:1.982mg/100g), zinc (2.39:3.69mg/100g) and calcium (2.2:4.2mg/100g) in that order, Rhyncho-Roll had trace amounts of magnesium (0.05mg/100g) and fair in phosphorus (11.53mg/100g); whereas Gala had fair amounts of magnesium (7.45mg/100g) and phosphorus (19.67mg 100g), Fatty acid composition of Rhyncho-roll was predominantly polyunsaturated fatty acids (PUFA) which comprised of linolenic acid (33.16%) omega-3 and linoleic acid (7.5%) omega-6 which are recommended for healthy function of the human heart. Gala had lower amounts of PUFA: linolenic acid (0.45%) omega-3 and linoleic acid (11.05%). and higher percent in oleic acid (43.13%), trace amounts of pallinic acid (0.13%) omega combined palmioleic acid (0.67%) omega-7 which are monounsaturated fatty acids (MUFA), Rhynco-roll contained fair amounts of oleic acid (15.61%) omega-9. Gala had higher amounts of stearic acid (41.76%), and lower in palmitic acid (3.12%) and NI (0.36%) which are saturated fatty acids (SFA) that are not good for human health. Rhyncho-r
