Proximate, Nutrient and Mineral Composition of Cuttlefish (Sepia recurvirostra)

Abstract

The proximate, nutrient and mineral analyses were conducted on the head and mantle of cuttlefish (Sepia recurvirostra). Proximate analysis showed both head and mantle of cuttlefish contained 13.16 -13.51% protein, 0.7- 0.9% ash, 0.8% fat and1-1.4% carbohydrate. Amino acid analysis revealed cuttlefish contained essential and non essential amino acid with arginine (0.97%) and glutamate (0.81%) was the highest in the head, respectively, while lysine (0.7%) and glutamate (0.7%) was the highest in the mantle, respectively. Lipid of cuttlefish contained high Percentage of Polyunsaturated Fatty Acid (PUFA) with a high content of DHA (17.5–20.5%). The C16:0 and C18:0 were the most abundant saturated fatty acid in the head and mantle. Mineral analysis showed high contents of sodium, phosphorus, potassium and calcium, with sodium content being the highest (1532.7-1610.4 mg/kg). Zinc and copper were the dominant trace minerals in both portions. This study showed that cuttlefish contain essential nutrients for human good health with high in protein and mineral content.
