The effects and functions of blue crabs and the nutritional value of blue crabs

Introduction of Blue Crab

The carapace of the blue crab is oval, the body is flat and hairless, the head and chest are well developed, the claws are strong, and the hind legs are shaped like a paddle, so it is called a paddle. The width of the head and chest is about 1.5 times the length, the back is raised and smooth; there is a clear "H"+ shaped indentation on the surface of the head and chest; there are 4 protruding triangular teeth on the forehead, the size and spacing of the teeth are roughly equal. There are 9 protruding triangular teeth of similar size on the front side edge.

Nutritional value of blue crab

1. Enhance immune function

Green crabs are rich in protein and trace elements, which are very nourishing to the body. The components of green crabs are rich in protein, among which the female gonads contain up to 30.98%, the highest protein content among fresh products. In addition, the protein amino acids of green crabs are complete, and the essential amino acid score is 84.23-93.58. Protein can promote human growth and development, maintain the body's nitrogen balance, and enhance immune function.

2. High nutritional value

Scylla serrata is rich in inorganic elements, especially Se and Ca, and is a seafood with high nutritional value and health functions.

3. Promote brain development, enhance the brain's learning and memory abilities, and prevent brain aging.

The body of mud crab is rich in fat and unsaturated fatty acids (UFA). The UFA of muscle is 74.58%, which is higher than 65.61% of swimming crab muscle and 74.3% of mantis shrimp head. The polyunsaturated fatty acids (PUFA) are as high as 47.83%, which is nearly 10% higher than 38.43% of swimming crab and slightly lower than 51.5% of mantis shrimp head. EPA is as high as 18.04%, DHA is 13.52%, which is equivalent to 15.21%, 17.69% of swimming crab, 15.75%, 13.96% of mantis shrimp head and commercial deep-sea fish oil products. The UFA of female gonads is also as high as 70.30%, the UFA of male gonads is 62.48%, and the lowest UFA of liver is 58.32%, which are all higher than swimming crab. The content of unsaturated fats in mud crabs is high, especially the ω-3 fatty acids EPA and DHA, which cannot be synthesized in the human body. EPA can significantly reduce the levels of triglycerides (TG) and cholesterol (TC) in serum, inhibit platelet aggregation and delay thrombosis, prevent and treat cardiovascular and cerebrovascular diseases and prostate hyperplasia, and DHA can promote brain development, enhance the brain's learning and memory abilities, and prevent brain aging.

4. Nourishing, anti-aging, and anti-cancer

Scylla serrata is a high-K and low-Na food. Therefore, scylla serrata is more suitable for patients with hypertension. Its liver has a very high Ca content, second only to stone snails, dace, dried shrimp, dried shrimp and anchovies, and the natural organic calcium is easy for the human body to digest and absorb. The content of other essential elements in scylla serrata, such as Mg, Fe, Cu, Zn, Mn, etc. is also high. The selenium content of each component of the crab is very high, especially the female gonad. Selenium is a component of glutathione peroxidase in the human body and participates in the synthesis of coenzyme A and coenzyme Q. It has the functions of protecting the structure and function of cell membranes, anti-oxidation, eliminating free radicals, antagonizing and reducing the toxicity of certain poisons, and stimulating the production of immunoglobulins and antibodies. The liver, pancreas, and kidneys of the human body contain more selenium, and the serum selenium and hair selenium content of cancer patients are reduced. Therefore, scylla serrata, especially the worm, has the effects of nourishing, anti-aging, and anti-cancer.
