This study aimed to evaluate the content of water, ash, protein, carbohydrate, an d lipid in four seaweeds ( Hypnea musciformis , Solieria filiformis , Caulerpa cupressoides and C. mexicana ). Algal constituents were determined by differenc e, gravimetric or colorimetric method, being the values expressed as g 100 g -1 dehydrated weight (d.w.). Results revealed that the water (10.7 ± 0.18-15.06 ± 1.14 g 100 g -1 d.w.), ash (7.79 ± 0.87-15.12 ± 0.51 g 100 g -1 d.w), protein (17.12 ± 0.99-20.79 ± 0.58 g 100 g -1 d.w.), lipid (0.33 ± 0.01-3.77 ± 0.13 g 100 g -1 d.w.) and carbohydrate (38.07 ± 0.32-54.24 ± 0.157 g 100 g -1 d.w.) contents varied between the species (p < 0.05). H. musciformis and S. filiformis (Rhodophyta) had highest ash contents (14.14 ± 1.23-15.12 ± 0.51 g 100 g -1 d.w.), whereas lipids were higher for Caulerpa species (Chlorophyta) (1.52 ± 0.17-3.77 ± 0.13 g 100 g -1 d.w.) (p < 0.05). Protein and carbohydrate were the most sources in all the species. Therefore, the studie d seaweeds could be a potential source of food ingredients for diets. 2014 artículo científico 1679-9283 https://www.redalyc.org/articulo.oa?id=187130419002 en http://www.redalyc.org/revista.oa?id=1871 Acta Scientiarum.
