Composición proximal del tejido muscular de seis peces comestibles recolectados en las costas nororientales de Venezuela

Abstract

Marine fish have been a source of food for humans since ancient eras. However, it seems that nutritional knowledge of this kind of food has not been completed properly, especially from those that occur in Venezuelan waters. The aim of this study was to evaluate the proximate, energetic, and lipid composition of six high-consumption-marine-fish. Proximate composition was obtained by standard analytic (gravimetric and spectrophotometric) methodologies, including total content of lipids, proteins (540 nm) carbohydrates (630 nm), water (moisture), and remainder minerals (ash). Statistical analyses indicated significant differences among species (P<0.05), being distributed into two to four homogenous groups. Results suggest that these marine fish (especially H. steindachneri and C. crysos) are a source of lean meet, rich in proteins, phospholipids, and minerals, which could be used by the food industries to manufacture new products with high nutritional value.
