In the present study, nutritional composition of the edible seaweeds, Gracilaria edulis (red seaweed), Ulva lactuca (green seaweed) and Sargassum sp. (brown seaweed) were evaluated. ). Palmitic acid (C16:0), oleic acid (C18:1) and linoleic acid (C18:2, ω-6) were the most abundant saturated fatty acid (SFA), monounsaturated fatty acid (MUFA) and polyunsaturated fatty acid (PUFA), respectively. Fatty acid profile also revealed that small quantity of docosahexaenoic acid (DHA) (C22:6, ω-3) ranging from 0.064 to 0.494% was present in all the three seaweed species but eicosapentaenoic acid (EPA) (C20:5, ω-3) was present only in Sargassum sp. at a concentration of 0.583%. G. edulis had higher vitamin D2 (2.590 mg 100 g -1 ), vitamin E (1.017 mg 100 g -1 ) and vitamin K1 (0.714 mg 100 g -1 ) than Sargassum sp. and U. lactuca. The results clearly indicates that these three seaweeds can be considered as a good source of dietary fibre, protein, minerals and vitamins and can be used for fortifying foods or as components of functional foods.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
