Indian seaweed species Enteromorpha linza, Enteromorpha prolifera, Ulva fasciata, Caulerpa taxifolia and Sargassum johnstonii from natural and cultivated populations were evaluated for food safety, and nutritional quality. Among the above seaweeds, Enteromorpha prolifera showed the highest caloric value and protein content, while these values were lowest in Sargassum johnstonii species of natural habitat. The lipid content was maximum in cultivated seaweeds of E. linza and U. fasciata species. Crude fiber varied within a narrow range in all the seaweeds analyzed. Protein efficiency ratio (PER) studies conducted with E. linza and U. fasciata showed low PER values compared to control rats fed on casein as source of protein. Acute oral feeding of seaweeds E. linza, U. fasciata, C. taxifolia and S. johnstonii and subacute oral feeding of E. linza for 12 weeks did not produce any toxic effects on male and female rats.
