This study was performed to investigate the contents of sulfites in 1,063 dried seaweeds in Seoul Chung-Bu market from March in 1999 to August in 2000. Sulfites of the samples were determined by Zn powder reduction method and Monnier-Williams's modified method. Two samples of 1063 (0.19%) were detected over 30ppm in SO₂ contents by Monnier-Williams's modified method. In samples detected over 30ppm, 2 brown algaes were 171.4ppm and 295.7ppm. By Zn powder reduction method, 54 dried seaweeds (54/1063 = 5.08%) were positive reaction (1-30ppm). These were 28 dried layers, 27 dried brown seaweeds and 2 sea cabbages. According to results, the quality test for the dried seaweeds must be reinforced to supply safety food for the citizens.
