Answer: If it is fresh sea cucumber, you don't need to soak it for 2-3 days. If it is dry sea cucumber, it usually takes about 2-3 days to soak, because dry sea cucumber is a dried and dehydrated product of fresh sea cucumber, which is hard and hard to soak thoroughly. In addition, water needs to be changed frequently during the soaking process, and the soaking time of sea cucumber is related to the drying degree of sea cucumber. Pay attention to avoid oil when soaking sea cucumbers, change water frequently, and choose pure water to make hair.

1. How long does the sea cucumber soak?

If it is fresh sea cucumber, you don't need to soak it. In dry sea cucumber, it usually takes about 2-3 days. Because dry sea cucumber is a dried and dehydrated product of fresh sea cucumber, its texture is dry and hard, and it is not easy to foam. Foaming takes at least 2-3 days, and water needs to be changed during foaming. At the same time, the foaming time of sea cucumber is related to the dryness of sea cucumber, and it takes longer for very dry sea cucumber.

Second, how to soak sea cucumbers?

1. Step 1: Prepare proper amount of sea cucumber, purified water and clean oil-free containers.

2. Step 2: Put the sea cucumber into a container, add the untouched sea cucumber, soak for about 1 day, and change the water every 6 hours until the sea cucumber becomes soft.

3. Step 3: Cut the soaked sea cucumber from bottom to top along the abdominal incision with scissors, then cut off the sand mouth of the sea cucumber head, remove the sea cucumber teeth and rinse it with water.

4. Step 4: Put the washed sea cucumber into the pot, pour in purified water, and continue to cook for about 15 minutes after boiling until the sea cucumber is completely soft.

5. Step 5: Pick out the soft and transparent sea cucumbers, leaving the hard-core sea cucumbers to continue cooking until the sea cucumbers are completely soft and transparent.

6. Step 6: Add water to the container, pour in the cooked sea cucumber and soak it in the fresh-keeping layer of the refrigerator for about 2 days. Pay attention to changing water 2-4 times in the middle.

Third, matters needing attention in soaking sea cucumbers

1. Oil repellent: Sea cucumber contains autolytic enzyme. If oil is encountered in the foaming process, the autolytic enzyme in sea cucumber will accelerate the dissolution of protein, reduce the nutritional value of sea cucumber, and the skin of sea cucumber may also fall off.

2. Change the water frequently: Pay attention to changing the water frequently when soaking the sea cucumber, otherwise the impurities in the water will affect the sea cucumber and cause the sea cucumber to drop slag.

3. Use pure water: It is advisable to use pure water when soaking sea cucumbers, because ordinary water has different hardness and contains more impurities. Soaking sea cucumbers with ordinary water will affect the growth rate of sea cucumbers.
