Resumen
El pescado y los mariscos son alimentos de los más completos por su calidad y cantidad de nutrientes;
sin embargo, poco se sabe sobre la composición química de los recursos pesqueros del pacífico
costarricense. Por tal razón, el objetivo del presente trabajo es determinar el potencial nutricional
de las partes comestibles (fresco) de seis especies de pescados y mariscos de consumo e importancia
comercial en la zona pacífica de Costa Rica. Los análisis de la composición proximal: humedad,
cenizas, extracto etéreo y proteínas se determinaron según la metodología de AOAC. Los resultados
indicaron que el contenido de humedad varió entre 77,13 % en barracuda (Sphyraena ensis) y 83,12%
en calamar (Lolliguncula panamensis), la ceniza entre 0,84% en calamar y 1,65% en almeja de agua
dulce (Anodonta luteola), el extracto etéreo entre 1,16% para el calamar y 2,24% para la almeja de agua
dulce. La almeja de agua dulce presentó el menor porcentaje de proteínas (10,73%), mientras que el
lenguado (Cyclopsetla querna) el mayor porcentaje (19,86%). Los resultados permiten concluir que
las especies estudiadas son una buena alternativa para el consumo humano, por su bajo contenido en
grasas y por el aporte proteico.
Fish and shellfish are the most complete foods due to their quality and quantity of nutrients. However, little is known about the chemical composition of the fishery resources of the Costa Rican Pacific Ocean. Therefore, this study aims to determine the nutritional potential of the (fresh) edible parts of six seafood species for consumption and with commercial importance in the Pacific area of Costa Rica. The proximate composition analysis—moisture, ash, ether extract and protein—were determined by AOAC methodology. The results indicated that the moisture content ranged from 77.13% for barracuda (Sphyraena ensis) and 83.12% for squid (Lolliguncula panamensis); ash was between 0.84% for squid and 1.65% for freshwater mussel (Anodonta luteola); the ether extract, from 1.16% for squid and 2.24% for freshwater clam. The freshwater clam had the lowest percentage of protein (10.73%); while the sole (Cyclopsetla querna) showed the highest percentage (19.86%). The studied species are a good alternative for human consumption due to their low fat and protein intake.
