Is it OK to soak kelp overnight? How long does kelp last?

Kelp can not be soaked in water overnight, otherwise the nutrients in it will dissolve into the water, resulting in a significant drop in nutrients, generally we put the kelp in water to soak for about 2-3 hours, but the water needs to be changed in time halfway, so as not to breed bacteria and other microorganisms, deterioration.

Kelp is very familiar to many people, it is a kind of macroalgae that lives in low-temperature seawater, can be edible, it is more common in China's coastal zone, the kelp on the market is basically dried kelp, you need to soak it in water before eating, but many times people are easy to soak it and forget it.

Under normal circumstances, kelp can not be soaked overnight, it usually only needs to use clean water to remove dust, sediment and other impurities, can not be washed hard, can not be soaked in water for a long time, otherwise the nutrients in it will dissolve into the water, resulting in a significant drop in nutritional value.

Kelp is usually soaked in water for about 2-3 hours, and the water needs to be changed in time halfway to avoid bacteria breeding and causing it to deteriorate.

Soak the kombu before boiling it, and if you want to eat it the next day, you can use rice water the night before.

Soaking kelp (if you don't have rice washing water at hand, you can also add a little salt or a little dry starch to the water where you soaked it) is all about soaking the kelp better.

After the kelp is soaked, wash it to remove the impurities on it, and then boil the kelp, it is best to boil the kelp in a pot under cold water (so that the boiled kelp is not fishy, there is no fishy smell), and then add a little vinegar to the water in which the kelp is boiled, and then boil it over high heat for 10 minutes, and the kelp can be quickly cooked.

The purpose of adding vinegar is not only to make the kelp cook quickly, but also to make the nutrients in the kelp better absorbed by the human body when eating).

The kelp is soaked in cold water for about 30 minutes, but it takes 24 hours to remove the arsenic content, and try to soak it for a long time before eating.

Generally speaking, the time of kelp soaking is determined according to the texture and arsenic content of kelp, if it is a kelp with a more tender texture and low arsenic content, then the soaking time does not need to be too long, but if the texture is relatively hard and contains more arsenic, it needs to be soaked for a longer time.

The value of kelp.

It should be noted that kelp has a high iodine content, and is also rich in protein, fat, dietary fiber, carbohydrates, thiamine, riboflavin, niacin, vitamin E, potassium, sodium, calcium, magnesium, iron, manganese, zinc, phosphorus, selenium, mannitol, carotene, vitamin B1, vitamin B2, niacin and other trace elements, is an alkaline food, with low calorie, medium protein, high mineral characteristics.

Kelp is a good anti-cancer food. Regular consumption of kelp can not only increase iodine intake, but also greatly enhance calcium absorption. It is believed that this may be one of the reasons for the anti-cancer effect of kelp.

The sodium alginate salt contained in kelp has the effect of preventing leukemia and stomach cancer.

The kelp should be soaked for about 3 hours, and the soaking time should not be too long, otherwise the water-soluble vitamins, inorganic salts and other nutrients in the kelp will be dissolved in the water, and the nutrients will be lost and the edible value will be reduced. Kelp can be steamed for half an hour, then soaked in water for 2 to 3 hours, and some baking soda can be added when steaming, which can speed up the soaking speed.

Soak the kelp for about 3 hours

Kelp should be soaked for about 3 hours, and the soaking time should not be too long, if it is too long, the water-soluble vitamins, inorganic salts and other nutrients in the kelp will also be dissolved in water, so that the nutrients will be lost, and the edible value will be reduced. If the soaked kelp is as weak as if it has been cooked, it means that the kelp has spoiled and can no longer be eaten.

Kelp can be steamed first and then soaked, first put the kelp in the steamer for half an hour, and then soak in water for 2 3 hours, when steaming, you can put a little alkaline noodles or baking soda in it, which can make the kelp gum be dissolved by alkaline substances, speed up the speed of soaking, and become very soft when boiling, and the taste will be more tender.

If you soak it in cold water, it will take a long time and soak it in hot water for a short time, but the high temperature of the hot water will cause a lot of nutrients in the kelp to be lost, and the taste will deteriorate. Soaked kelp can be washed with rice water, which can retain the original delicious taste of kelp, and can also shorten the soaking time, and the rice washing water is weakly alkaline, and can also neutralize alginic acid substances.

Dried kelp needs to be soaked for 1-2 hours.

Soak the kelp in cold water, if you feel that soaking the kelp in cold water is too slow, and want to soak the kelp quickly, you can use warm water to soak the kelp.

Soak the kelp in cold water for half an hour, then carefully wash off the sand and salt on the surface of the kelp, remove it, put the kelp in a container with a lid, soak it in warm water for 2 hours, then take it out and put it in a clean basin, and finally gently rub it until mucus appears on the surface of the kelp, and wash it off under running water.

How to make kelp:

1. Three fresh kelp shreds.

Soak the kelp, wash it, cut it into shreds, blanch it in boiling water for 5 minutes, put it in cold water and take it out, drain the water and put it in a container, put the meat and magnolia slices.

Cut ginger into shreds and mix with various seasonings on the side and mix in kelp.

2. Sweet and sour kelp.

Soak the kelp in clean water, remove it and dig it dry, cut off the yellow edge and white shoots, cut it into pieces, put it in boiling water and blanch it for 3 minutes, cool the ridge, and remove the water. Mix sugar, vinegar and water in a sandwich pot and boil together, cool it and pour it into the jar, and turn the jar once the next day to enjoy.

Kelp is a large marine brown algae plant that grows in low-temperature seawater, which is a seaweed plant and has the reputation of "longevity vegetable", "sea vegetable" and "iodine-containing champion". So can kelp be soaked overnight?

1. Kelp should not be soaked overnight. Otherwise, the nutrients in it will dissolve into the water, resulting in a significant drop in nutrients, generally put the kelp in water and soak it for about 2-3 hours, but pay attention to the need to change the water in time halfway.

2. Kelp is a perennial large edible algae with large, brown and flat bands. It is divided into blades, stalks and holders, and the holders are pseudoroot-shaped. The leaves are composed of epidermis, cortex, and medullary tissues, and the lower part of the leaves has sporangia.

It has a mucus cavity and secretes a slippery substance. Anchors have tree-like branches that attach to seabed rocks and grow in cooler waters.

That's it for the introduction of can you soak kelp overnight.

Kelp should not be soaked overnight. The nutrients in the kelp will dissolve into the water overnight, resulting in a significant drop in nutrients, generally we put the kelp in the water to soak for about 2-3 hours, but the water needs to be changed in time halfway, so as not to breed bacteria and other microorganisms, and there will be deterioration. Kelp usually only needs to be cleaned with clean water to remove dust, sediment and other impurities, and cannot be washed vigorously or soaked in water for a long time.

Kelp contains algin, alginic acid, and other substances, which form a viscous colloid on the surface of the kelp once it absorbs water, preventing further water from entering, so it is difficult to cook it thoroughly when cooking. If the kelp is not as tough as if it is boiled after being soaked in water, it means that the kelp has spoiled and can no longer be eaten.

Precautions for boiling kelp: Before boiling kelp, you should first soak the kelp, if you want to eat it the next day, you can soak the kelp in rice water the night before (if you don't have rice water at hand, you can also add a little salt or a little dry starch to the water where you soaked the kelp), the purpose of this is to make the kelp better soaked.
