Saccharina japonica is a marine species of the Phaeophyceae (brown algae) class, a type of kelp or seaweed, which is extensively cultivated on ropes between the seas of China, Japan and Korea.[1] It has the common name sweet kelp.[2] It is widely eaten in East Asia.[3] A commercially important species, S. japonica is also called ma-konbu (真昆布) in Japanese, dasima (다시마) in Korean and hǎidài (海带) in Chinese.[3] Large harvests are produced by rope cultivation which is a simple method of growing seaweeds by attaching them to floating ropes in the ocean.[1][4]
The species has been cultivated in China, Japan, Korea, Russia and France.[5] It is one of the two most consumed species of kelp in China and Japan.[1] Saccharina japonica is also used for the production of alginates, with China producing up to ten thousand tons of the product each year.[6]
S. japonica contains very high amounts of iodine. Excessive consumption (15 g/day, containing 35 mg iodine) suppresses thyroid function, though thyroid hormone levels remain within normal limits.[7]
