There are 20 kinds of edible sea cucumbers in China. Among them, Stichopus japonicus in the Yellow Sea and Bohai Sea are the most valuable. Sea cucumber existed in Precambrian more than 600 million years ago. It was not until the Three Kingdoms period that there was a formal literature record. Wu Guoying's "Records of Foreign Bodies in Linhai Water" records: "The earth meat is as big as a child's arm, five inches long, with a belly in the middle and no mouth, full of three feet and baked."
Among them, "local meat" refers to sea cucumber. There is a record about sea cucumber in Five Miscellanies written by Xie Zhao in Wanli period of Ming Dynasty: Sea cucumber is produced in Liaodong seaside, which is warm and tonic, so it is called sea cucumber. By the Qing dynasty, sea cucumber had been regarded as a delicacy at a high-level banquet of aristocratic families. ?
Stichopus japonicus is cylindrical and cucumber-shaped, with a body length of 2. Stichopus japonicus is cylindrical, cucumber-shaped, 20-40 cm long and 3-6 cm wide. Its cross section is slightly quadrangular, and its ventral surface is as flat as the sole of a foot. The abdomen is cm, the cross section is slightly quadrangular, and the abdomen is as flat as the sole of the foot. The ventral surface faces the ground, and the tube feet are arranged in irregular three longitudinal zones along the three areas on the ventral surface.
The back is slightly raised, with large conical spines, which are arranged in 4-6 irregular longitudinal lines, and the mouth is biased towards the front ventral surface. The main economic types of Stichopus japonicus are Stichopus japonicus, Stichopus japonicus, Stichopus japonicus and Stichopus japonicus. At present, Stichopus japonicus belonging to the Yellow Sea and Bohai Sea has the highest value and is called the "crown of ginseng". ?
Sea cucumbers are distributed vertically from the intertidal zone to the shallow sea with a water depth of 30 meters. Living at the bottom of a rock reef with stable waves, no fresh water inflow and abundant algae or at the bottom of a hard sediment with algae. Its food is small animals and plants, such as foraminifera, gastropods, scratching feet and diatoms. The sea environment for living is very demanding. If there is pollution or heavy metals (lead, mercury, arsenic) exceed the standard, it is difficult to survive. Sea cucumber grows slowly, and it takes about three years to grow into an adult.
Modern scientific research has proved that sea cucumber contains more than 50 kinds of nutrients beneficial to human physiological activities, among which protein is extremely high, including 18 amino acid taurine, chondroitin sulfate, sea cucumber mucopolysaccharide, calcium, phosphorus, iron, iodine, zinc, selenium, vanadium, manganese and vitamin B 1, B2, nicotinic acid, etc.
Contains 1, nicotinic acid and other vitamins. Of the 18 amino acids, 8 are essential amino acids that cannot be synthesized by human body itself. Amino acid is the basic substance that constitutes protein and the main material basis of human life activities.
Arginine is the most abundant, which is called "arginine monopoly". Arginine is the main component of male sperm cells and the main raw material for synthesizing human collagen, which can promote the regeneration of body cells and the repair of damaged bodies, improve human immune function, prolong life and eliminate fatigue.
Taurine and nicotinic acid in sea cucumber have the functions of regulating nervous system, quickly eliminating fatigue and preventing skin aging. In addition, taurine, lysine and methionine contained in sea cucumber are almost absent in plant foods. Pharmacological experiments show that chondroitin sulfate and Stichopus japonicus mucopolysaccharide contained in sea cucumber have special effects on human growth and development, anti-inflammatory osteogenesis, prevention of tissue aging, promotion of wound healing and inhibition of various cancer cells.
There is also precious sea cucumber element in sea cucumber. Its molecular structure is similar to saponin, and it is the glycoside of hydroxysterane derivative. Its medical and health care value is extremely high. Scientific research has proved that it has obvious therapeutic effect on stroke spastic paralysis.
