The number of sea cucumbers is used to indicate the size of sea cucumbers. The smaller the number of sea cucumbers, the larger the sea cucumbers. The number of sea cucumbers per catty has a great relationship with its variety, origin and other factors.
Among the producing areas of sea cucumbers, the sea cucumbers produced in Liaoning and Shandong are more representative, among which the varieties of sea cucumbers are better. Generally speaking, the light dry sea cucumber produced in these places is about 20- 100 heads per catty. Under normal circumstances, the lower the number of heads, the higher the market price.
Most sea cucumbers are dry products, and good sea cucumbers are full in shape, heavy in weight, thin in skin and thick in meat wall. The water swells after it is developed, and it is waxy, smooth, elastic and free of sand. Good water-soaked sea cucumber has bright color, no hard heart inside, elastic meat and complete meat spines. If the sea cucumber is red, soft and sticky, or very thin, the meat is thin, the pit is big, and the meat thorn is lodging and not straight, it is not suitable to buy.
There are many factors that determine the nutritional value of sea cucumber, mainly the following factors.
1, the size of sea cucumbers will be different with different places of origin. Sea cucumbers in the south generally grow very big, because the natural environment is different and the temperature of water is higher than that in the north, so sea cucumbers grow fast, usually in one year they can grow to the size of sea cucumbers from Liaoshen for three years. We all know that the longer the growth time, the slower the growth and the higher the nutritional value.
2. The drying degree is different. Because of the autolysis reaction of the sea cucumber itself, the sea cucumber must be made into dry sea cucumber for preservation, while the process of making dry sea cucumber includes light drying, salt drying and sugar drying, such as sugar dry sea cucumber and salt dry sea cucumber. Each sea cucumber has a lot of sugar or salt, and there are not many sea cucumbers per catty. We can't always say sugar dry sea cucumber or salt dry sea cucumber.
