Comparability of Chemical Composition and Functional Properties of Shell and Flesh of Penaeus notabilis

Emmanuel I. Adeyeye, Habibat O. Adubiaro and Olufemi J. Awodola    

Abstract: The chemical composition and the food properties of shell and flesh of Penaeus notabilis were evaluated. The protein, ash and energy were high whereas carbohydrate and fibre were low in the proximate composition. In the mineral composition, the mineral elements in shell were corresponding higher than the level in flesh. The total essential amino acids in shell was 740mg/g protein and 865mg/g protein in flesh. The limiting amino acid in both shell and flesh was threonine. In the functional properties, both water absorption, oil absorption and oil emulsion capacities were all high with foaming stability at 25% (90min) in both tissues. The lowest gelation was low in both tissues. The protein solubility was high at both sides of pH with isoelectric point being 5.0 (shell) and 7.0 (flesh). The followings: proximate, mineral, amino acids and essential amino acids composition, functional properties and protein solubility, all showed that correlation coefficients r-values > t , n-2 meaning that the correlations were significant with high positive values at r0.05.
