In this study, variations in Capsosiphon fulvescens composition with area and during the harvest period were assessed by analysis of crude protein, ash, and carbohydrate content. C. fulvescens in Janghung showed the highest crude protein content in December and the highest carbohydrate content in February. Changes in total amino acid, free amino acid, and fatty acid content were observed between December and February. Total amino-acid content of Janghung samples tended to decrease over the course of the harvest period, from 35.7â±â0.2 g 100 g−1 in December to 32.9â±â0.2 g 100 g−1 in February. Total amino-acid content in Janghung and Gohung samples was higher than that in Wando, except for glutamic acid. Significant increases in the major fatty acids (C12:0, C14:1 n-5, C18:0, C18:1 n-9, C18:2 n-6, C18:3 n-3, C20:0, C20:1 n-9, C22:1 n-9, C22:6 n-3, and C24:1 n-9) in Janghung were observed as the harvest period progressed. Fructose was the most abundant and glucose the second most abundant in the monosaccharide composition profiles, while galactose, ribose, and lactose were present in low quantites and mannitol, fucose, and arabinose were not detected.
