The traditional processing technology can be roughly divided into the following steps: deveining, cleaning, cooking, dehydration, pickling, rubbing with plant ash, and drying. The current processing technology eliminates the rubbing based on the traditional processing technology. This step of plant ash is changed to water washing, and the steps are: deveining, cleaning, cooking, dehydration, pickling, washing, and drying (drying).

Let’s take a brief look at a few steps:

1. Deveining - remove the internal organs of fresh sea cucumbers.

2. Cleaning - remove residual sediment.

3. Cooking - put it into a pot and cook it with boiling water.

4. Dehydration (salting) - Stir the cooked sea cucumbers with coarse salt grains, and use the salt to dehydrate the sea cucumbers. It is also a mild pickling process, commonly known as salting! The presence of a small amount of salt can effectively play a preservative role and ensure that sea cucumbers will not deteriorate during the long-term air-drying process, which usually takes 3-4 days.

5. Pickling - Boil saturated salt soup to soak and pickle sea cucumbers.

6. Rubbing plant ash - Rubbing the surface of sea cucumbers with plant ash to beautify the appearance of sea cucumbers. Since it will form a suspension on the water surface when hair is made, it is basically no longer used.

7. Water washing - rinse briefly with fresh water to remove the salt on the outer layer of the sea cucumber and retain the salt inside the body.

8. Drying (drying) - the drying process of sea cucumbers. Sea cucumbers are dried by air drying. Currently, in order to save time, drying rooms are generally used for drying.

Preparation of Laodian Dried Sea Cucumber:

Production process: fresh sea cucumber→deveined→cleaning→cooking→dehydration→drying→finished product

Advantages: Technology Simple, short cycle, better preservation of sea cucumber nutrients! It is easy to store and can be guaranteed not to deteriorate for more than 5 years at room temperature!

Disadvantages: poor appearance! When drying, the salt will spread to the surface of the sea cucumber and form white salt crystals. The salt crystals will not only facilitate the storage of the sea cucumber, but also make the sea cucumber look unsightly. At the same time, because the sea cucumber contains less salt, it cannot support the overall structure of the sea cucumber, and it is easy to dry out!

Preparation of light-dried sea cucumbers:

Production process: fresh sea cucumbers → gutting → cleaning → cooking → dehydration → drying → washing → drying → finished product

Advantages: The process is simple, the cycle is short, and the nutrients of sea cucumbers are better preserved!

Disadvantages: poor appearance, easy to dry out like old light dry ones. The storage time is shortened because the body of ginseng originally contains less salt, and then washing away the protective salt layer on the surface will shorten the storage time.

Fake light dried sea cucumbers have different names due to different regions. They are generally called salted dried sea cucumbers. There are two types:

Pure salted dried sea cucumbers. The specific production process is as follows:< /p>

The production process of salt-dried sea cucumbers once: fresh sea cucumbers→deveined→cleaning→cooking→dehydration→drying→pickling→drying→finished product

The production process of salt-dried sea cucumbers twice: fresh sea cucumbers Sea cucumber → devein → wash → cook → dehydrate → dry → pickle → dry → pickle → dry → become

Salt and dry production process of three times: fresh sea cucumber → devein → clean → cook → Dehydration → Drying → Pickling → Drying → Pickling → Drying → Pickling → Drying → Finished product

You may have seen that the so-called salting is a process of pickling and drying, and so on for five Salting is to repeat pickling and drying 5 times.

Features: Easy to preserve. The nutrition of salted dried sea cucumbers is still good. However, each time it is salted (commonly known as vat creation), the cost will be reduced and the nutrition of sea cucumbers will be lost. It is recommended not to buy it. Salted dried sea cucumbers with more than 2 times of salt!

Washed and salt-dried sea cucumbers are based on pure salt-dried sea cucumbers with additional steps of washing and drying. The specific production process is as follows:

Better washed and salt-dried sea cucumbers: fresh sea cucumbers → Deveined → Cleaning → Cooking → Dehydration → Drying → Pickling → Drying → Washing → Drying → Finished product

Almost washed and salt-dried sea cucumbers: fresh sea cucumbers → Deveining → Cleaning → Cooking → Dehydration → Drying → Pickling → Drying → Pickling → Drying → Washing → Drying → Finished product

As you can see, it is just salt-dried sea cucumbers that have been washed with salt several times, but washed sea cucumbers are generally They are all salt-dried sea cucumbers that have been salted 1 to 2 times, because the inside of the sea cucumber has been saturated after being salted more times, and most of the salt is attached to the surface of the sea cucumber. If it is washed with water again, the gain will outweigh the loss!

Generally, the salt layer on the surface of salted dried sea cucumbers only feels slightly thicker than that of old and light dried sea cucumbers, and the difference is not obvious! But once the salt is dried, it will rarely dry out! Because the cell tissue of the ginseng body already contains a certain amount of salt, the skin of the sea cucumber appears thicker and the overall body is rounder. Moreover, there are still holes in the abdominal cavity of the sea cucumber at this time, so the salt-dried ones currently on the market that use salt more than once are pretending to be old. It is light dry, but the fake light dry after being washed with salt and salt once is pretending to be light dry!

Sugar-dried sea cucumber

In the process of processing dried sea cucumbers, the sea cucumbers are "soaked and dried" in white sugar, and the sugar content in the weight of the dried sea cucumbers is used to increase the weight to reduce the weight of the dried sea cucumbers. The selling price of sea cucumbers, for the purpose of cost saving, this type of sea cucumbers are called "sugar-dried sea cucumbers".

The first step in processing sugar-dried sea cucumbers is to sprinkle a mixture of salt and sugar evenly on the cooked sea cucumbers and marinate them for 4 to 5 days. The purpose is to drain the water from the sea cucumbers so that they can be absorbed more Sugar; the second step is to put the remaining salt-sugar mixture after pickling in a large pot, cook the pickled sea cucumbers repeatedly to maximize the absorption of sugar, and then dry them to achieve weight gain. Another purpose of boiling it with sugar is to make the appearance of sea cucumbers black and shiny. Many consumers who don’t understand sea cucumbers often like to buy this kind of good-looking sea cucumbers.

Freeze-dried sea cucumber

Freeze-dried sea cucumber is made from fresh sea cucumber. After careful cleaning, the fresh sea cucumber is quickly frozen to minus 35 in a freeze-drying warehouse. Temperature - 45 degrees, the water in the sea cucumber freezes, and then the ice is directly sublimated into water vapor in a vacuum state, thereby achieving the purpose of dehydrating the water in the sea cucumber. The cost of truly good freeze-drying processing is very high.
