Título: Nutritional profile of edible marine macroalgae: macronutrients
Data de publicação: 2014
Resumo: In this study, the nutritional profile of widely consumed species of seaweed (commerciallyavailable in the Portuguese market) was evaluated. Three brown macroalgae, Undariapinnatifida (Wakame), Laminaria japonica (Kombu) and Hizikia fusiforme (Hijiki), and threered ones, Palmaria palmata (Dulse), Porphyra tenera (Nori) and Eisenia bicyclis (Arame),from different geographical origins (Japan and Galiza, Spain) were analysed. The chemicalanalyses were performed to determine moisture, ash, protein, fat and carbohydrate contents.The algae samples are commercialized dry, therefore, the moisture content was very low(~10%). The ash content was around 17-38% in brown algae and 10-17% in red algae. Proteinlevels ranged from 6 to 33%. The highest levels were found in red species, especially inPorphyra tenera. The fat content was less than 1%. The carbohydrate content, which includesthe dietary fibre, ranged from 38 to 69%. The results of this work show that the analysedmacroalgae can be interesting alternative sources of protein, minerals, and, eventually, fibre.Further studies are being conducted in order to better characterize these species in whatconcerns to their chemical composition and potential health effects.
