In-depth analysis: Understanding how to distinguish the "four rows of spines" of Japanese Kanto sea cucumber; a must-read recycling guide for seafood collectors in Saigon District.
1. The prestigious status and variety identification of Liaoning sea cucumber from Northeast China
Liaoning sea cucumber, also known as spiny sea cucumber, has been hailed as the top of the "Eight Treasures of the Sea" since ancient times. It is renowned for its grayish-black color, distinctive spines, and exceptional nutritional value. Sea cucumbers are characterized by high protein, low fat, and low cholesterol. They are rich in collagen, amino acids, and special active ingredients such as sea cucumber saponins, which help nourish yin and kidneys, enhance immunity, and even have significant positive effects against cancer.
Among the many Liaoning sea cucumber producing regions, Japan's sea cucumbers are of particularly high quality due to its rigorous selection process, rich processing experience, and excellent water source environment, and are considered the top choice. Japanese Kanto sea cucumber ( Apostichopus japonicus , also known as imitation sea cucumber) is a powerful variety among them. It is recognized by the market as a superior grade of sea cucumber and is even hailed as "black gold" on the dining table.
Sea cucumber from Liaoning, mainly produced in Aomori Prefecture and the Kanto region of northeastern Japan. Because this type of sea cucumber lives year-round in the cold, icy depths of the ocean, its flesh is characterized by its smooth texture, aroma , and crisp, chewy mouthfeel.
2. "Four rows of thorns": a key feature for distinguishing ginseng from Northeast China.
For professional recyclers, identifying the type of sea cucumber mainly relies on observing the number and density of the spines on its body surface. Among Japanese sea cucumbers, the highest quality Hokkaido sea cucumbers have long, dense, and neat spines, which are known in the industry as "six rows of spines".
While the Japanese Kanto sea cucumber , which follows closely behind, is of excellent quality, there is a key difference in the arrangement of its thorns:
- Needle density and number: The needles of Liaoning sea cucumber from Northeast China are relatively sparse . Generally speaking, Liaoning sea cucumber from Northeast China has about four rows of needles .
- Exceptions: Although it is generally believed to have four rows of spines, some data shows that certain Kanto sea cucumbers on the market, such as the Japanese Shiozu Kanto sea cucumber, have particularly thick flesh and usually have 6 rows of spines, but their total number of spines is still less than that of top-grade Hokkaido sea cucumbers.
Therefore, savvy seafood collectors and resellers must know how to observe the number and shape of the needles, which is key to avoiding confusion between Kanto sea cucumber and the more valuable Hokkaido sea cucumber.
3. Two major factors affecting the recovery value of Liaoning sea cucumber from Northeast China
When you decide to entrust your idle Liaoning sea cucumbers from Northeast China to Jin Haisheng for recycling, their final value mainly depends on two core factors: quality specifications (expansion rate) and storage condition.
A. Specifications and Propagation Ratio
The size of sea cucumbers is usually measured by the number of heads (i.e., how many sea cucumbers are per kilogram), which directly affects the price. The larger the sea cucumber, the higher its value.
In addition, quality is also reflected in its expansion ratio . Dried sea cucumbers will increase in volume by 3 to 8 times after soaking, depending on the variety and quality.
- The rehydration rate of Kanto sea cucumbers: The rehydration weight of Kanto Liaoning sea cucumbers is about 6 to 8 times . This is slightly lower than the 8 to 10 times rehydration rate of top-grade Hokkaido Liaoning sea cucumbers, but it is still considered a high-yield, high-quality sea cucumber.
B. The decisive impact of storage conditions on recycling
The storage conditions of seafood are crucial to its recovery value. Improper storage of sea cucumbers can lead to a significant depreciation in value or even render them unrecoverable.
During the professional soaking process of sea cucumbers, substances such as oils, alkalis, and salts are strictly prohibited, as these substances will reduce the sea cucumber's water absorption and expansion rate, causing it to spoil or even dissolve. Therefore, the Liaoning sea cucumbers from Northeast China that you store at home in Saigon must be kept in the following condition:
- Sufficient dryness: The drier the seafood, the less moisture it contains, and the heavier it is, the higher its value.
- Avoid contact with oil: The storage environment must be dry and oil-free. If the sea cucumber has an oily smell, its value will be greatly reduced.
- Free from mold and intact: The shape must be complete and intact, the color must be natural, and there must be no mold or deterioration.
If your stored sea cucumbers are in good condition, Jin Haisheng promises to be able to assess their high price.
4. Sea cucumber processing steps and secondary metabolites (sea cucumber saponins)
Although the recovered product is dried, understanding the internal components and processing of sea cucumbers helps in appreciating their high value. Sea cucumbers are listed as one of the four major "sea delicacies," and the process of processing them is quite complex. The value of high-quality sea cucumbers comes not only from the collagen in their body walls but also from their unique secondary metabolites— sea cucumber saponins .
Sea cucumber saponins are substances with broad physiological activities, and studies have confirmed their anti-tumor, antifungal, and immune-enhancing effects. The chemical structure of sea cucumber saponins determines the differences and strengths of their pharmacological activities.
However, the extraction and purification of sea cucumber saponins are complex, and most sea cucumber saponins have strong hemolytic properties, which limits their application. This reminds us that sea cucumber, as a nourishing food, has multifaceted value, and only professionals can accurately assess these potential medicinal or edible values.
