Gracilaria edulis, a red alga present in southeast coast of India was evaluated for its nutritional composition. FT-IR analysis of soluble polysaccharides revealed the presence of galactans, 3,6-anhydroa-L-galactopyranose, sulphated galactose and the gelling agent agar, with the sulphate content estimated as 51.01 hg/mg of polysaccharide. Results of physicochemical properties and nutritional profile reveal the presence of dietary fibre (8.9 0.62% OW), carbohydrate (101.61 1.8 mg/g DW), crude protein (6.68 0.94 mg/g DW) and lipid content (8.3 1.03 mg/g DW). G. edulis contains biologically important fatty acids like palmitic acid (2.06%), linolenic acid (2.56%), and oleic acid (1.98%). The other nutritional components present in high amounts are proline, chlorophyll A and B, all the essential amino acids and vitamin A, E and C. These findings suggest that G. edulis has potent nutritional value which might be used as a source of nutrients for human and animals. (C) 2014 Elsevier Ltd. All rights reserved.
