It is not possible to directly identify the good and the bad because there is no direct correlation between the number of thorns on a sea cucumber and its quality.
The sea cucumber's thorns are directly related to its growing environment and species, and there is no direct connection between the nutritional value and quality of the sea cucumber. Generally, sea cucumbers with more thorns, such as red cucumbers from Hokkaido, Japan, and wild sea cucumbers from Russia, have six rows of thorns, which looks like a dense ball of thorns, whereas wild sea cucumbers and farmed sea cucumbers in China basically belong to the 4 rows of thorns, and there are also 2 rows of thorns of sea cucumbers, mostly Kansai sea cucumbers from Japan. The sea cucumber has 4 rows of spines and 2 rows of spines, which are mostly Japanese Kansai sea cucumbers.
2 The longer the thorns, the better the sea cucumberIf it is the same species of sea cucumber, the longer the thorns, the better the sea cucumber.
Since the length of the thorns of different species of sea cucumber varies, such as the thorns of Fujian cage farmed sea cucumbers are bald, while the thorns of Dalian captive sea cucumbers are long and thin, it is not possible to compare the advantages and disadvantages of sea cucumbers by the length of their thorns.
However, when picking a sea cucumber of the same species, if the surface of the sea cucumber is with thorns and is straight and intact, it means that the sea cucumber's growth period is sufficient and its nutritional value is relatively high, whereas if the thorns are shorter, blunted or mutilated, the sea cucumber is a low-quality sea cucumber, which is probably not grown enough to be sold in the market, and belongs to an incomplete quality, and its nutritional value of its consumption is much lower than that of normal sea cucumbers. The nutritional value of the sea cucumber is much lower than that of a normal sea cucumber.
3 Sea cucumbers with sharp or rounded spinesThe thicker and stronger ones are better.
The sea cucumber's thorns are very relevant to the growth environment. Generally, the domestic farmed sea cucumbers have a short growth period and don't need to hunt for food by themselves, and the farmed sea cucumbers are shallow, with little pressure, relatively quiet environment, and there is no natural tide and other factors, so their thorns become long and thin; while wild sea cucumbers are grown in the deep sea area, and they are subjected to tens of meters of water depth pressure, ocean currents, tides, etc., and they need to rely on themselves to hunt for food. The wild sea cucumber grows in the deep sea area, due to the pressure of dozens of meters of water depth, ocean currents, tides and other tests, coupled with the need to rely on their own predation, the amount of activity, the sea cucumber thorns have become thick, short, short, powerful, compared to the natural nutritional value is also higher.
4 Is the sea cucumber good without thornsNot really, on the contrary, sea cucumber with thorns is more nutritious and better.
According to whether the sea cucumber has conical spines or not, the sea cucumber can be divided into "spiny sea cucumber" and "light skin cucumber", the light cucumber is the sea eggplant that we often see, and some places also call it stone cucumber, red gourd cucumber, piggery cucumber and so on. There is not much difference between sea cucumber with thorns, but the difference in nutritional composition is relatively large, light cucumber can only be used in vegetables, while the spiny ginseng can be used in both vegetables and medicine, so the nutritional value of the spiny ginseng is much higher than the light cucumber, and the spiny ginseng with the best tonic effect belongs to the spiny ginseng, which has a thick body wall and red glutinous meat, and it is regarded as the crown of the sea cucumber. The 3-5 years wild ginseng in the sea area of Shandong Peninsula and Liaodong Peninsula is the best.
