Kelp is a large perennial edible algae. Spores are large, brown and flat. It is divided into leaves, stalks and fixators, and the fixators are in the shape of pseudoroots. The leaf is composed of epidermis, cortex and marrow, and there are sporangia in the lower part of the leaf. It has a mucus cavity, which can secrete slippery substances. A tree-like branch of fixator, which is used to attach rocks on the seabed and grows in seawater with low water temperature.

Kelp is an important marine resource with low cost and rich nutrition.

The algae body is a long oblate leaflike body, brown-green, with two longitudinal grooves running through the middle of the leaf, forming an intermediate zone, which is generally 1.5-3 m long, 15-25 cm wide, 6 m long and 50 cm wide.

habitat

Kelp is born on a rock 2 meters below the low tide line at the seaside, cultivated artificially and grown on ropes or bamboo.

geographical distribution

Kelp belongs to the algae in the sub-frigid zone, endemic to the North Pacific Ocean, and there are some kelp distributed in the Atlantic Ocean. Kelp is mostly distributed in the northern hemisphere, a small amount in the southern hemisphere, and generally grows on seabed rocks in the subtidal zone. The growth of kelp is mainly affected by temperature, light, nutrients and plant hormones.

The northwest Pacific Ocean is the concentrated growth place of kelp, and most kelp varieties in the world are distributed here. The coastal waters of Liaodong Peninsula and Shandong Peninsula in China are widely distributed.

Main value

For food. Protein of kelp contains many kinds of amino acids, especially eight essential amino acids for human body, and its content is very close to the pattern of essential amino acids in ideal protein. Kelp can be used not only as a dish, but also as various foods with unique flavors.

For feeding. Adding kelp powder to feed can effectively improve the nutritional structure, reduce the feeding cost, increase the weight, increase the egg production rate, reduce the mortality rate and improve the quality of cultured varieties.

Fucoidan, mannitol, dietary fiber and sodium alginate were extracted from kelp as industrial raw materials.

nutritional ingredient

Kelp is rich in laminarin, and there are three kinds of polysaccharides found at present: fucoidan, fucoidan and fucoidan starch. It also contains acidic polysaccharide, fucoidan, fucoidan, galacturonic acid, laminin, taurine, bifidus factor and other active ingredients. Kelp is a kind of nutritious edible brown algae, which contains more than 60 kinds of nutrients.
