    • Red Alga “Dulse”

      Dulse is a red algae that grows in cold waters. Dulse can be eaten

      overseas, but most of it was unused in Japan. In particular, it was

      difficult to dispose of a large amount of dulse because it grew on

      the culture rope for kelp, a special product of Hakodate.






      Nutrients in Dulse

      Dulse, like other red algae such as laver (“Nori” in Japanese), contains a lot of protein and the amount is comparable to soybean. On the other hand, it contains a lot of carbohydrates, especially dietary fiber. 

      Dulse’s cell walls contain polysaccharides classified as dietary fibers called xylan.

      This xylan has an unusual structure that is different from that of land plants.
