Another thing to tell you is:
Sea cucumber is listed as one of the "eight treasures of seafood", which is warm and sweet, and has the effects of tonifying kidney and replenishing essence, nourishing blood and moistening dryness. Sea cucumber is a nourishing treasure with extremely high nutritional value and extremely low cholesterol content. A large number of studies have also confirmed that sea cucumber has high medicinal value, especially suitable for tumor adjuvant, nourishing and anti-aging treatment, but if cancer patients are weak and have too much phlegm, they should not be used more. The anti-fungal efficiency of sea cucumber saponin extracted from sea cucumber is 88.5%, which is the first anti-fungal saponin discovered by human beings from the animal kingdom.
The number 1. is complete and correct. This is very important, because it can explain the freshness and quality of sea cucumber. Incomplete sea cucumbers are often left after vendors remove the corrupt parts. In addition, the twisted and shriveled shape shows that the sea cucumber has been caught for a long time, and it is easy to get sick and be contaminated by microorganisms, leading to deterioration.
2. Dry enough, that is, the water content is less than 15%. Because sea cucumber is expensive, the lower the water content, the more affordable it is. In order to gain high profits, some merchants often mix too much water into sea cucumbers, which not only makes consumers suffer in price, but also benefits the growth and reproduction of microorganisms, which is not conducive to the preservation and quality assurance of sea cucumbers.
3. Light mouth, strong and shiny. Whether it is firm and shiny indicates the nutritional richness of sea cucumber. Sea cucumbers living in food-rich sea areas are mature, with high nutritional content and high value.
4. The size is even, and there is no sand in the abdomen. In order to make huge profits, some vendors illegally fill the belly of sea cucumbers with sand, salty salt or alum to increase the weight of sea cucumbers.
In addition to the above four points, please note: to buy sea cucumbers, you should go to state-owned shopping malls and reputable businesses to prevent being cheated and causing unnecessary losses.
