One, the difference in growth conditions:

1, kelp is a kind of large marine brown algae grown in low-temperature seawater. Kelp growth is mainly affected by temperature and light, the amount of nitrogen nutrient content in seawater, but also affects the growth and yield of kelp. In addition, the tide, wind and waves also have a greater impact on the growth of kelp.

2, purslane generally grows in the shallow sea on the rocky reef.

3, purslane leafy body grows in the intertidal zone, like the wind and waves, the tide is smooth, nutrient-rich salt sea area. Strong dryness; suitable light intensity of 5000 to 6000 lux, with a high light saturation point, light compensation point is low, is a high-yield crops.

Second, the family is different

1, kelp is an aquatic plant belonging to the brown algae family Buccoaceae.

2, seaweed, also known as "purple English", "son of the vegetable", "cabbage", belongs to the red cabbage plants.

3, seaweed is the commercial name of the striped seaweed (P. yezoensis). Its English name is Seaweed , Japanese English is Nori. Japan, South Korea is a big consumer of seaweed, Japanese cuisine of sushi, is one of the common way of consumption.

Three, the appearance of different

1, kelp than seaweed broad and thick, flexible flat as a band, about one or two feet long to three or four feet, color brown, fishy taste, is the genus of kombu algae, can be used as a band to tie up the object, so the name of the kelp, also known as fine kombu.

2, nori is also divided into leaf, petiole and fixation of three parts, different kinds of leaves of different shapes and sizes, altar nori leaf-like body is long blade-like, wide base, tip acuminate, leaf thin like membrane, the edge of the few folds, natural growth of 30 ~ 40 cm long, 3 ~ 5 cm wide; cultured good leaf length up to 1 ~ 2 meters.

3, seaweed for the dried seaweed, generally processed into thin slices, very thin.

Four, different colors

1, seaweed belongs to the brown algae, fresh green, dried close to black.

2, nori belongs to the red algae, the color has a purple-red, green purple and black purple, but dried into purple.

3, seaweed color is generally black purple.

Extended information

The benefits of seaweed are not only in terms of nutrition, it is more commendable health effects. British researchers in the 1990s found that seaweed can kill cancer cells and enhance immunity. Seaweed contains algae bile protein with lower blood sugar, anti-tumor application prospects, which polysaccharides have anti-aging, blood lipid, anti-tumor and other aspects of biological activity. Alginic acid contained in seaweed also helps to remove toxic metals in the body, such as strontium and cadmium.

Medical personnel also developed from seaweed with unique activity of marine drugs and health food, can effectively prevent nerve aging, regulate the body's metabolism. In addition, seaweed can prevent and treat peptic ulcers, delay aging, and help ladies keep their skin lubricated and healthy. Folk there is often let the postpartum women eat some seaweed recipe, it is said to have obvious effect of lactation. There is also the role of weight loss .

Seaweed is so light that you can only eat a few grams to a dozen grams a day, so it doesn't mean much in terms of providing protein and fat. In contrast, its significance in providing micronutrients is more appreciated.

Seaweed has all the benefits, but Chinese medicine believes that seaweed taste sweet and salty, cold, can clear heat, phlegm, diuretic, eat more seaweed in the summer has to eliminate heat, complement the body's role in high blood pressure, tuberculosis patients, foot, lung heat and phlegm is suitable for more seaweed, but the spleen and stomach cold, easy to bloating people should not be eaten more. Due to the seaweed in the processing of flavored, contains more salt, and therefore the need to control salt people should also be appropriate restraint seasoned seaweed consumption, can be appropriate to eat some unseasoned nori sheet.

Nutritional value of nori

(1) protein and amino acids? Purple cabbage's life-active substances, very important for plant life activities. Edible purslane general protein content of 24% -28%, much higher than the average vegetable, and the body's essential amino acid content. The constituent amino acids of purslane protein such as alanine, aspartic acid, glutamic acid, glycine, proline and other neutral and acidic amino acids are more, which is a feature not found in all terrestrial vegetable plants.

(2) Fat Compared with terrestrial plants, the fat content of purslane is low, mostly below 1%. In the fat of purslane, the saturated fatty acid chondroitric acid accounts for the majority of the saturated fatty acid, about 20%; cinnamic acid, stearic acid content is less, respectively, accounting for 2%; unsaturated fats that have a very good health care effect on the human body - linoleic acid, linolenic acid or octadeca tetraenoic acid is more, 10% - 30%, 10% - 30%. The content of linoleic acid, linolenic acid or octadecatetraenoic acid, which have good health effects on human body, is 10% - 30%, and the highly unsaturated fatty acids above C20 also have certain content. What's more, the content of eicosapentaenoic acid, which has been compared to "brain gold", is as high as 30% in seaweed.

(3) vitamins Seaweed contains a variety of vitamins, B vitamins content and vegetables compared to no less. Seaweed B vitamins, especially in terrestrial plants almost non-existent vitamin B12 content is very high, measured in dry matter, vitamin B12 content is similar to fish, vitamin C content is also very high. Vitamin B12 has the effect of activating brain nerves, preventing aging and memory loss, and improving depression.

(4) Inorganic substances Because seawater is rich in inorganic components, and seaweed has the function of absorbing and accumulating inorganic substances in seawater, the inorganic substances in seaweed are extremely rich.
