CATDOLL : CATDOLL: What nutrients does seaweed contain?

1. What nutrients does seaweed contain?

The nutritional value of seaweed is high

1. Protein and Amino Acids

The life-active substances in laver are very important for plant life activities. Edible laver generally has a protein content of 38%-43%, which is much higher than that of ordinary vegetables, and has a high content of essential amino acids. The general composition of laver (in terms of dry matter%) is protein 43.6, fat 2.1, carbohydrate 44.4, fiber 2.0, and ash 7.5. The amino acids that make up laver protein, such as alanine, aspartic acid, glutamic acid, glycine, proline, etc., are more neutral and acidic amino acids, which is a feature that terrestrial vegetables and other plants do not have.

2. Fat

Compared with terrestrial plants, the fat content of laver is low, mostly below 1%. Among the fat in laver, the saturated fatty acid palmitic acid accounts for the vast majority, about 20%; the content of myricic acid and stearic acid is relatively small, accounting for 2% respectively; the content of unsaturated fats that have a good effect on human health, such as linoleic acid, linolenic acid or octadecatetraenoic acid, is relatively high, ranging from 10% to 30%, and there is also a certain content of highly unsaturated fatty acids above C20. At the same time, the content of eicosapentaenoic acid, which is likened to "brain gold" in laver, is relatively high, accounting for about 30%.

3. Vitamins

Nori contains a variety of vitamins, and its content of B vitamins is comparable to that of vegetables. Nori contains a high content of B vitamins, especially vitamin B12, which is almost non-existent in terrestrial plants. Its content of vitamin B12 is similar to that of fish in terms of dry matter, and its vitamin C content is also high.

4. Inorganic substances

Seawater contains extremely rich inorganic components. Nori has the function of absorbing and accumulating inorganic substances in seawater, so nori contains rich inorganic substances.

2. What is the nutritional status of seaweed?

Nori is a kind of red algae plant that grows on shallow sea reefs. Its colors vary from purple-red, green-purple to black-purple, but they all turn purple after drying. Although this purple marine plant is an algae, it can be eaten as a vegetable, so it is named nori.



 Nori is not only delicious, but also rich in nutrition, especially the high iodine content. Therefore, it was used in ancient times to treat goiter caused by iodine deficiency, which is now called "thyroid enlargement". Since nori has the function of softening and dispersing nodules, it can also be eaten by people with other stagnation and accumulation. Nori contains rich choline components, which can enhance memory. Because it contains a certain amount of mannitol, it is a strong diuretic and can be used as a supplementary food for the treatment of edema. Nori is rich in calcium and iron. It is not only an excellent food for treating anemia in women and children, but also can promote the growth and health of bones and teeth in children and the elderly.



Laver is suitable for all people except those with abdominal pain and loose stools. It is more suitable for patients with edema, beriberi, early stage of lung disease, goiter, cardiovascular disease and various lumps and hyperplasia.



Note: To remove pollution and toxins, please soak the product in water before use and change the water once or twice. People with poor gastrointestinal digestion should eat less; people with abdominal pain and loose stools should not eat it.

3. The difference between sand-free laver and deep-sea laver

Most of the products labeled "sand-free laver" or "deep-sea laver" on the packaging are tan laver made into round cakes.

"Sand-free" just means that it is washed more cleanly before processing, and it does not have any other special meaning.

"Deep sea" is a concept that is created out of nothing. All of China's seaweed is produced from nearshore mudflats, so where does the "deep sea" come from?

5. Application of optical dispersion! ! Urgent! ! ! !

The intensity of left-handed circularly polarized light changes with the wavelength, which is called circular dichroism, or circular dichroism dispersion spectrum. In pharmacy, circular dichroism spectrum and circular dichroism dispersion spectrum are mainly used for the study and qualitative identification of the three-dimensional structure of psilocybin compounds, alkaloids, amino acids, antibiotics and sugars.

6. What are the applications of redox reactions in life?

Food corruption and metal corrosion are both redox reactions, which are not good for humans. However, metal preparation, chlor-alkali industry, sulfuric acid and nitric acid preparation are also redox reactions, which are beneficial to humans.
