Fatty acids; proximate and amino acid composition of Anarcadium occidentale protein concentrate were investigated. The three most abundant fatty acids were C18:1ω 9 > C16:0 > C18:3 ω 3. Unsaturated fatty aids predominated in the sample with adequate amounts of essential fatty acids. Proximate analysis of protein concentrate revealed high percentage crude protein of 69.6g/100g protein. Ash and crude fibre were low while ether extract was not detected. The protein concentrate had a balanced content of some of the essential amino acids, with respect to the FAO/WHO provisional pattern however supplementation may be required in valine and threonine. The calculated isoelectric point (pI) was 4.25 while the first limiting amino acid was valine.
