Learn more about seaweed

Seaweed is a collective term for ‘macroalgae’ or ‘plants’ at sea. Unlike 'microalgae', they are visible to the naked eye. The group, which is also called sea vegetables, is very diverse with over 10,000 species globally and approx. 450 in Norway.

As a coastal nation, we Norwegians have always lived of the sea. Of cod, saithe, crabs and scallops, and seaweed. The use of sea plants dates back several thousand years, to when we lived by hunting and fishing, and harvesting wild plants was an important source of food.

Quality and food safety are important. The seaweed companies have in collaboration developed Guidelines for growing and processing sugar kelp and winged kelp to ensure a good product and several of the farmers are Debio-approved. A summary of the status of food safety and documented nutritional content in the most important cultivated species today, sugar kelp and winged kelp can be read here.


As food, one can compare seaweed with fruits and vegetables

The different sea vegetables have many different flavors, characteristics, textures and colors, and differ from each other in the same way as apples, pumpkins and herbs.

sugar kelp

The sugar kelp (Saccharina latissima) is thin and delicate and has a sweet taste. This is where it got its name from.

The sugar kelp is therefore well suited for pastries such as biscuits, cakes and tarts, and can be used for kraft, dashi or chips. It is well suited as an accompaniment to fish, meat, cheese and vegetables.

winged kelp

The winged kelp (Alaria esculenta) resembles long feathers and has a hard midstripe.

Winged kelp is excellent for miso soup, rich vegetable soups and stews. It is rich in calcium and has a chicken-like taste with rice. Winged kelp is well uncooked for salads if marinated in lemon juice.
