Generally speaking, the nutritional value of wild sea cucumbers is much higher than that of cultured sea cucumbers. The wild environment has created high-quality sea cucumbers, and there are relatively many active substances accumulated in wild sea cucumbers. There are two ways to cultivate sea cucumbers. One is to cultivate sea cucumbers in shrimp ponds or around the sea. The second is artificial seedling raising, which is put back into the sea to grow on its own, that is, bottom sowing sea cucumber, which can also be regarded as wild sea cucumber. At present, pure wild sea cucumbers and bottom-sown sea cucumbers are mixed together and cannot be distinguished. From the point of nutritional value, the water level in the seawater or shrimp pond around the dam is very shallow, with plenty of sunshine, and the sea cucumber grows rapidly with little nutrient accumulation. In addition, in the process of breeding, some sea cucumber farmers add antibiotics to the ponds for breeding sea cucumbers in order to prevent and control pests and diseases; In order to promote the rapid growth of sea cucumber, growth hormone is added to feed, which leads to the drug residue of adult sea cucumber and is potentially harmful to human body. In recent years, the problem of excessive heavy metals in aquatic products has gradually become the focus of food safety. Some sea cucumber culture areas are adjacent to pollution sources. If sea cucumbers live in such a polluted environment all the year round, the consequences can be imagined.
Comparison of nutritional value between fresh sea cucumber and water-borne sea cucumber
It is generally known that eating seafood is alive and has higher nutritional value, but sea cucumber is different. The nutrients of fresh sea cucumber are mostly surrounded by colloid, which is not easily absorbed by human body. The nutrient absorption rate of fresh sea cucumber is only about 5%. Eating fresh sea cucumber not only does not absorb much, but also tends to have diarrhea. Therefore, sea cucumbers are generally not easy to eat raw. Soaked sea cucumber is dry sea cucumber. After soaking in water, the cell wall of sea cucumber can be broken, so that the nutrients of sea cucumber can be better absorbed by human body. However, after a long period of high-temperature cooking and blistering, especially improper production, its nutritional components are seriously destroyed.
