Research Abstract

Iodine is an essential mineral for human, however excess intake of iodine results in thyroid disorder. Edible blown algae, Konbu or Laminaria sp., are rich in iodine, and only 1 g of dried konbu contains about 2 mg of iodine, which correspond to the tolerable upper intake level. In this study, a new method for reducing iodine in konbu keeping their quality has been developed. By this method, about 90% of iodine could be removed from konbu with a yield of 90%.
