How to eat fresh sea cucumber, light dried sea cucumber and how to keep it fresh

Light dried sea cucumbers and fresh sea cucumbers are different in preservation methods. Light dried sea cucumbers are sea cucumbers made by removing internal organs, washing, boiling, shrinking, and drying. The preservation method is mainly to put them in a dry and ventilated environment, avoid putting them in the refrigerator or a dark storage cabinet, to prevent the absorption of water and the return of moisture, the breeding of bacteria and the deterioration. If the light dried sea cucumber is not finished after soaking, you can continue to soak it in 0-5 degree cold water, change the water every 12 hours, and it can be stored for three days; if there is a lot left, you can put the soaked sea cucumber in plastic wrap or a small list, store it individually, and store it in the freezer compartment of the refrigerator, so that the storage time can be up to 3 months.

Fresh sea cucumber is a fresh sea cucumber caught directly from the sea, and its preservation and consumption methods are relatively simple. Fresh sea cucumber can be cooked in a variety of ways, such as scallion-cooked sea cucumber, stewed, cold salad, etc. The correct way to eat fresh sea cucumber includes boiling, stewing, cold salad, etc. You can choose to eat a soaked sea cucumber every morning on an empty stomach to obtain its nutritional value.

In conclusion, light-dried sea cucumbers need to pay special attention to the dry and ventilated environment of the preservation environment to prevent moisture regain and deterioration, while fresh sea cucumbers rely more on freshness and direct consumption. Both have their own characteristics in preservation and consumption, and consumers should choose the appropriate treatment method according to their own needs and conditions.

What are the specific production process and steps of light dried sea cucumber?

The specific production process and steps of light dried sea cucumber mainly include the following links:

1. Soaking: First, put the dried sea cucumber in a clean and oil-free container, add an appropriate amount of water (pure water is recommended for the whole process) for soaking. According to different materials, the soaking time varies, some recommend soaking for about 48 hours until the sea cucumber is soft, while other materials mention that it needs to be soaked for 30 minutes to remove sediment, or 24 hours.

2. Cleaning: After soaking, cut the sea cucumber along the incision, take out the sand nozzle, and wash it with running water. This step is designed to remove impurities and unclean substances inside the sea cucumber.

3. Cooking: The cleaned sea cucumber needs to be cooked. The specific cooking time and method vary in different materials, but generally an appropriate amount of water is added to the steamer for cooking 36.

4. Baking or sun exposure: Cooked sea cucumbers require baking or sun exposure to remove excess moisture and maintain their texture.

5. Steaming and drying: This step may involve further drying to ensure that the sea cucumber reaches the desired level of dryness.

6. Packaging: Finally, pack the processed sea cucumber for easy storage and transportation.

It should be noted that different materials may vary in the details of some steps, such as the time and method of soaking, the specific operation of cooking, etc. Therefore, in the actual operation process, the steps and details may need to be adjusted according to the specific situation.

What are the fishing methods for fresh sea cucumbers and how to ensure their freshness?

The fishing methods of fresh sea cucumber mainly include diving fishing and using small steamboats to pull sea cucumber nets for towing. Diving fishing is by divers diving into the deep sea, using underwater lights or sensors and other tools to find sea cucumbers, and then fishing manually. Another method is to use small steamboats to pull sea cucumber nets (commonly known as sea cucumber rakes) for towing, which is generally operated by 4-5 people. When harvesting, a relatively flat area should be selected, and it is best to choose a good weather for harvesting45.

In order to ensure the freshness of fresh sea cucumbers, the following preservation methods can be adopted:

1. Put the sea cucumber in a plastic bag, remove the air from it as much as possible and store it in the freezer compartment of the refrigerator. This method can maintain the freshness and quality of the sea cucumber for a long time. 2. Vacuum preservation method, that is, put the sea cucumber in a vacuum bag, extract the air from it and store it in the refrigerator, which can effectively maintain the freshness and taste of the sea cucumber.

3. Salting preservation method, wash the sea cucumber and marinate it in salt water, and then store it in the refrigerator. This method can prolong the storage time of the sea cucumber without affecting its taste.

4. Air-drying preservation method. After cleaning the sea cucumber, put it in a cool place to dry, and then put it in a sealed bag for storage. Although the storage time is short, it can maintain the nutrients and taste of the sea cucumber. It should be noted that before storage, make sure that the sea cucumber has been thoroughly cleaned, remove internal organs and foreign bodies, and avoid direct sunlight. In addition, low temperature refrigeration is one of the most ideal storage methods. Low temperature can inhibit the growth of microorganisms and slow down the metabolism of sea cucumbers, thereby prolonging their preservation time.

What are the differences in nutritional value between light dried sea cucumbers and fresh sea cucumbers?

The difference in nutritional value between light dried sea cucumber and fresh sea cucumber is mainly reflected in the protein content, the type of nutrients and the content of some specific nutrients.

From the perspective of protein content, fresh sea cucumbers contain about 16.5 grams of protein per 100 grams, while light dried sea cucumbers have a protein content of more than 55% 53. This suggests that light dried sea cucumbers may have a higher degree of protein concentration, but it should be noted that this high protein content does not mean that its nutritional value is absolutely higher than that of fresh sea cucumbers, because the quality of protein is also important.

In terms of the types of nutrients, both are rich in protein, calcium, potassium, zinc, iron, selenium, manganese and other active substances, as well as acidic mucopolysaccharides, arginine and other beneficial ingredients 55. However, fresh sea cucumbers also contain a lot of acidic mucopolysaccharides, lipids, visceral pigments, etc., which may be reduced in light and dry sea cucumbers due to dehydration during processing.

As for the content of some specific nutrients, although the specific values are not directly mentioned, it can be inferred from the evidence that there may be differences in the specific content of these nutrients between light-dried sea cucumbers and fresh sea cucumbers due to the loss or change of certain nutrients during processing. For example, the iodine content in fresh sea cucumbers is 6000 μg/kg 54, while this data is not explicitly mentioned in light-dried sea cucumbers, possibly due to the loss of iodine during light drying.

The difference in nutritional value between light dried sea cucumber and fresh sea cucumber is mainly reflected in the level of protein content, the difference in nutrient types and the change of specific nutrient content. Light dried sea cucumber may perform better in protein concentration, but fresh sea cucumber may have an advantage in the retention of certain nutrients and active ingredients.

How to properly soak light dried sea cucumber to maintain its optimum taste and nutrition?

The correct way to soak light dried sea cucumber to maintain its optimum taste and nutrition is as follows:

1. Preparation: First, wash the dried sea cucumber and put it in an oil-free container, as the oil will reduce the autolysis of the sea cucumber. Use purified water instead of tap water for soaking, as tap water may contain ingredients that are unfavorable to sea cucumbers.

2. Soaking and softening: Put the container containing the sea cucumber into the refrigerator refrigeration or fresh-keeping layer. According to different materials, the soaking time is recommended to be 24-48 hours, or even 72 hours. Adding ice cubes to the water can speed up the soaking process. Change the water at least once a day, some recommend changing the water every 12 hours, and some recommend changing the water 1-2 times a day 70.

3. Sectioning and washing the sea cucumber: After soaking the sea cucumber until it is soft, cut it along the abdomen with scissors to remove the white annular sand nozzle on the head and wash it clean.

4. Boiling: Put the treated sea cucumber into a pot, bring to a boil over high heat, and then continue to cook for about 30 minutes. Take it out after it cools naturally.

5. Soak again: The cooked sea cucumber is soaked in pure water at 0-4 ° C again. During this period, the water needs to be changed. The specific frequency depends on the hardness and taste of the sea cucumber. It is generally recommended to change the water every 6 to 10 hours, and change the water twice to three times.

6. Check the taste: During the second soaking process, you can try the taste of the sea cucumber. If it still feels hard, you can change the water again and continue to soak.

Through the above steps, the light dry sea cucumber can be effectively soaked to maintain its best taste and nutrition. It should be noted that any water containing oil or salt should be avoided during the entire soaking process, so as not to affect the quality and taste of the sea cucumber.

What are the special precautions when freezing dried sea cucumbers?

When freezing dried sea cucumbers, there are a few special precautions to follow:

1. Before freezing, the sea cucumber should be thoroughly cleaned and its outer skin removed to ensure that the sea cucumber retains its freshness and texture during the freezing process.

2. Put the cleaned sea cucumber in a sealed bag or sealed container, remove air and put it in the freezer compartment of the refrigerator. This step helps prevent the sea cucumber from absorbing too much moisture during the freezing process, thus avoiding moisture.

3. The temperature of the freezer should be kept below -18 ° C to ensure that the sea cucumber is preserved for a long time without deterioration.

4. Avoid the sea cucumber from touching oil, because if it touches oil, it is likely to cause the sea cucumber to dissolve.

5. If the number of frozen sea cucumbers processed is too large, you can wrap the sea cucumber in plastic wrap, then place it in mineral water, and then take it out when eating.

It should be noted that although light dried sea cucumbers can be stored by freezing, the freezing time should not be too long. For frozen sea cucumbers, they need to be thawed before eating. In addition, for dried sea cucumbers, freezing is not recommended, because during the freezing process, due to the high humidity in the refrigerator, dried sea cucumbers can easily absorb water and are prone to deterioration after moisture. Therefore, when deciding whether to freeze dried sea cucumbers, the choice should be made according to the specific situation and needs.
