Dried sea cucumber contains 76.5% protein, fat 1. 1%, inorganic salts, sugars, phosphorus, iron, iodine and other nutrients.
In addition, sea cucumber also has high medicinal value. According to the medical records, sea cucumber has the function of tonifying kidney and replenishing essence, and has certain curative effect on treating tuberculosis, aplastic anemia and diabetes.
Sea cucumber contains an acidic mucopolysaccharide, which can inhibit the growth and metastasis of malignant tumors.
The following four methods to distinguish light dry sea cucumber are very effective:
Smell, good sea cucumber, like any seafood, has a good fresh smell;
Lick, a good sea cucumber tastes neither salty nor sweet, and does not stick to the tongue;
Ok, good sea cucumbers weigh very little, and there is a crisp sound when they are lightly hit. On the contrary, they are not light dry sea cucumber but mostly processed sea cucumbers;
Break off, salty and fake sea cucumbers are easy to break off, or feel like stones, while good sea cucumbers are elastic and slightly shriveled.
The difference between wild and captive is very obvious:
Foot: Wild Stichopus japonicus generally grows in the sea area with a water depth of about 20 meters, and looks for food through foot action, so the foot grows short and thick; However, the captive sea cucumber does not need to move because of long-term use of the bait put by the breeder, and lives in shallow water area, so the action function of the bottom foot decreases, the adsorption force is poor, and it becomes slender.
Sand mouth: The sand mouth of wild sea cucumber is big and hard.
Meat quality: Wild sea cucumber grows slowly because of its deep water area (15 to 20m), low water temperature, less sunshine, thick and elastic meat, wide and full tendons and rich nutrients; The captive sea cucumber grows fast, and the meat is soft and not tight (this is very similar to a pig that has been slaughtered for three months).
Morphology: wild sea cucumber is spindle-shaped, with thick tips at the middle, short and chubby, and looks very strong; The captive sea cucumber is slender and lacks tenacity.
Wart foot: Wild sea cucumber grows in harsh environment with many storms, insufficient bait and more activities. The spines on the back and sides are very thick and have different thicknesses. However, captive sea cucumber has small wind and waves, rich bait, less activity and long spines.
Growth years: wild sea cucumber generally grows for more than 4 to 5 years before reaching the fishing standard. The longer the time, the more nutrient deposits and the greater the nourishing value. However, the captive sea cucumber is rich in bait at a suitable temperature, and its growth speed is fast. Generally, it can be sold when it reaches the commodity specification of 5-8 heads, and its health and nourishing effect is relatively poor.
In addition, the wild sea cucumber tastes strong, without astringency, and the incision is delicate, neat and even.
As an expensive tonic, it is recommended that you should pay attention to choosing wild sea cucumbers as the first choice for nourishing and giving, rather than blindly choosing fast-growing captive sea cucumbers.
People who are not suitable for eating sea cucumbers: Children generally should not eat more sea cucumbers. Experts pointed out that sea cucumber is mainly glial protein, which belongs to incomplete protein and has low nutritional value. At present, the sea cucumber health products approved by the Ministry of Health are required to indicate "not suitable for children". Therefore, he suggested that infants should not eat sea cucumbers. Don't eat if the spleen and stomach are weak, but you can take sea cucumber health food selectively. In particular, patients with acute enteritis, bacillary dysentery, cold, expectoration, asthma, thin stool, bleeding with blood stasis and damp pathogen block should not eat. Experts remind that sea cucumbers are slippery and not suitable for people who often have diarrhea to eat a lot of sea cucumbers. Because fresh sea cucumbers may carry bacteria or even viruses, raw sea cucumbers are more likely to cause diarrhea, and their nutritional value is not easily absorbed by the human body. People who are easily allergic to protein should not eat more sea cucumbers. People with poor kidney function can't eat sea cucumber. Protein of sea cucumber is too high, which will increase the burden on the kidneys. At the same time, although patients with liver diseases should consume a certain amount of high-quality protein every day, if they eat too much, it will bring some pressure to the liver, so the daily consumption should not exceed 50 ~100g. Patients with arthritis and gout should not eat too much. Protein content of sea cucumber is extremely high, which can produce more uric acid during metabolism. If it is not excreted in time, it can form urate crystals in joints after being absorbed by human body, which will aggravate the patient's condition. Cancer patients should not eat sea cucumber before operation.
