At present, in the coastal areas of China, water pollution is very serious, so it is not easy to eat fresh and safe seafood. In recent years, in order to purify the sea area and cultivate aquatic products sustainably, many coastal areas began to cultivate organic sea cucumbers. Organic sea cucumber refers to the natural introduction of wild sea cucumber seedlings in the sea area that achieves the goal of purifying seawater, so that they grow naturally, with a symmetrical posture and a black and shiny color. Now there are pure natural organic sea cucumbers in the waters around Huludao in Dalian and near Long Island.
Identification method
Sea ginseng, bird's nest and shark's fin are equally famous, making it one of the eight treasures in the world. The domestic consumption level is increasing day by day, and the supply and demand of sea cucumbers are also rising. How to distinguish organic sea cucumber from common sea cucumber is a thorny problem for consumers at present.
In fact, it is easy to tell whether sea cucumber is common or organic. At present, we can distinguish whether sea cucumbers are ordinary sea cucumbers or organic sea cucumbers by the following methods.
Sea cucumber feet: organic sea cucumbers generally grow in the sea area with a water depth of about 20 meters. They look for food through the action of their feet, so their feet grow short and thick; However, captive sea cucumbers do not need to move because they use the bait put by ordinary people for a long time, and live in shallow water, so the action function of their feet is reduced, the adsorption force is poor, and they become slender.
Sea cucumber sand mouth: The sand mouth of organic sea cucumber is big and hard.
Meat quality of sea cucumber: Organic sea cucumber grows slowly because of its deep water (1.5 to 20m), low water temperature, little sunshine, thick and elastic meat, wide and full tendons and rich nutrition; The captive sea cucumber grows fast and its meat is soft but not tight (this is very similar to a pig that has just been slaughtered for three months).
Sea cucumber shape: organic sea cucumber is spindle-shaped, with thick tips at both ends, short and chubby, and looks strong; Captured sea cucumbers are slender and lack toughness. Verrucous foot: Organic sea cucumber has harsh growth environment, many storms, insufficient bait and many activities. The spines on the back and sides are thick and vary in thickness; However, captive sea cucumber has less wind and waves, rich bait, less activity and long thorns.
Growth period of sea cucumber: organic sea cucumber generally needs to grow for more than 4 to 5 years to reach the fishing standard. The longer the time, the more nutrients are deposited, and the greater the nourishing value; However, captive sea cucumber is rich in bait and grows fast at suitable temperature. Generally, it can be sold if it reaches the specifications of 5-8 heads, and the health and nourishing effect is relatively poor.
In addition, the organic sea cucumber has a rich taste, no astringency, and the incision is delicate, neat and even.
As an expensive tonic, it is suggested that we should pay attention to choosing organic sea cucumber as the first choice for nourishing and giving, rather than blindly choosing fast-growing captive sea cucumber.
