Caposiphon fulvescens was dried by the hot-air (50$^{\circ}C$), vacuum (50$^{\circ}C$), and freeze drying methods. The green alga contained high proportions of carbohydrates (38.10~41.54%), ash (31.86~33.28%), and crude proteins (17.46~23.03%) regardless of the drying methods used to prepare the sample. The total sugar contents of the hot-air and vacuum dried samples were higher than that of the freeze dried sample (p<0.05). Vitamin C content of the freeze dried sample was higher than that of either the hot-air or vacuum dried samples (p<0.05). The major amino acids were glutamic acid, proline, and aspartic acid, which amounted to 33.34~34.80% of the total amino acid content depending on the drying methods used. Total mineral content of either the hot-air or vacuum dried samples was significantly higher than that of the freeze dried sample (p<0.05). Regardless of the drying methods, Na, K, Mg, Ca, and P were the most abundant elements in the samples while trace elements were identified as Fe, Mn, Zn, and Cu.
