Abstract
The purpose of this study was to provide basic date for organic acid, vitamin and free sugar contents of commercial dried lavers cultivated in Korea (Seocheon, Wando, Goheung and Busan). The contents of organic acid per 100 g of dried lavers were in the range of 1,238.67~1,437.00 mg of malic acid, 1,021.67~1,309.67 mg of oxalic acid, 1,035.67~1,247.33 mg of citric acid, 1,001.00~1,146.00 mg of succinic acid, 902.00~1,107.00 mg of tartaric acid, 862.67~1,070.67 mg of lactic acid and 370.33~421.67 mg of acetic acid. The concentration of vitamin A and ${\beta}$-carotene were the highest (0.286 mg and 22.19 mg/100 g) in dried lavers cultivated from Seocheon and Wando. Vitamin $B_1$, $B_3$ and $B_{12}$ concentrations were the highest (9.79 mg, 19.15 mg and 1.77 mg/100 g) in dried lavers cultivated from Goheung, and vitamin $B_2$, $B_6$ and $B_9$ concentrations were the highest (4.55 mg, 2.36 mg and 2.17 mg/100 g) in dried lavers cultivated from Wando. The concentration of vitamin C and E contents were the highest (219.33 mg and 1.75 mg/100 g) in dried lavers cultivated from Wando. The contents of free sugar per 100 g of dried lavers were in the range of 214.27~347.72 mg of galactose, 59.10~71.69 mg of glucose, 37.86~54.34 mg of fucose and 6.26~14.65 mg of mannose.
