Kelp. 2 Is it okay to soak kelp for a long time?

After the kelp is soaked for a long time, there is a certain loss of nutrients.

Among them, vitamin B1 and niacin will lose some of them; The loss of trace elements and mannitol with dietary therapeutic effect is more; There is also a certain loss of iodine.

3 How to soak kelp well.

1. A better way to soak is dry steaming: untie the bundle of kelp, put the dried kelp in the steamer and steam it for 30 minutes, rub it with alkaline noodles after taking it out, and soak it in water for 2-3 hours. It is crispy and tender, and there is no fishy smell, and it is soft and delicious when used for stewing, stir-frying, and cold dressing.

2. When boiling kelp, the boiling time should not be too long, otherwise the more you boil, the harder it will become. If it is boiled hard, adding some vinegar can also make the kelp softer; Or add a few spinach sprigs while soaking to have the same effect.

3. You can use rice washing water to soak kelp, which is easy to hair, easy to wash, and easy to be soft when boiling, and some can add a little edible alkali or baking soda when boiling kelp, but pay attention to adding alkali not too much, and the boiling time should not be too long.

1. You don't have to drink tea immediately after eating kelp (tea contains tannins), and you don't have to eat sour fresh fruits immediately (sour fresh fruits contain green plant acids). Because of the abundant and colorful iron in kelp silk, the above two ingredients block the digestion and absorption of iron in the body.

2. Patients suffering from hyperthyroidism do not need to eat kelp, because the iodine in kelp silk is more colorful, which will aggravate the condition.

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.

Kelp is generally soaked for three hours, so let's take a look at the correct statement and steps.

Generally, most of the kelp we buy is dried kelp, before burning the kelp, we generally need to soak the dried kelp first, so how to soak the dried kelp, in fact, the correct way to soak should be steamed first and then soaked.

1.We should first rinse the kelp slightly, then put the kelp in the steamer and steam for about half an hour, if you want the kelp to cook softer in a shorter time, you can put some baking soda in the steamed kelp.

2.Then soak in clean water for about three hours, you can put an appropriate amount of vinegar in the water, or you can use rice washing water to soak directly.

3.Kelp should not be soaked for too long, kelp is rich in vitamins and minerals, and soaking in water for a long time will lead to a decrease in nutrients in kelp. In addition, kelp contains alginic acid, which is likely to produce a sticky substance when exposed to water, preventing water from entering, thereby prolonging the time for kelp to bubble.

Do not soak the kelp for too long, if the kelp has already appeared to rot when pinched, it should not be eaten. There are salt and impurities on the surface of kelp bought, and it contains arsenic, so it needs to be soaked, but not the longer the soaking time, the better, under normal circumstances, soak for about 5 hours, and then cook directly, or steam the kelp for half an hour, and then soak it for 2-3 hours.

It depends on how long it has been soaked and what it looks like now.

Kelp has a high nutritional value and is rich in protein, fat, carbohydrates, dietary fiber, calcium, phosphorus, iron, carotene, vitamin B1, vitamin B2, niacin, iodine and other trace elements. Traditional Chinese medicine believes that kelp is salty and cold, non-toxic, and has the effects of soft and hard dispersion, phlegm and asthma, passage and water, fat removal and blood pressure reduction; It can treat carbuncles, food and lodging, poor urination, cough and asthma, edema, high blood pressure and other diseases. Modern medical research has shown that sodium alginate salt is extracted from kelp, which has a hypotensive effect.

However, those with kelp cold, spleen and stomach deficiency should avoid eating. Kelp contains a certain amount of arsenic, and ingesting too much arsenic can cause acidosis. Before eating kelp, it should be rinsed with water to dissolve the arsenic in water, soak for 24 hours and change the water frequently, so that the arsenic content in the kelp can meet the food hygiene standards.

Kelp should not be used as a staple food for a long time, as excessive iodine intake will also have an impact on your health. Moreover, kelp contains a certain amount of arsenic, and excessive ingestion of arsenic can cause poisoning. Therefore, before eating kelp, it should be rinsed with water to dissolve the arsenic in water.

2.Do not soak kelp for a long time before eating, because if the soaking time is too long, the nutrients in kelp, such as water-soluble vitamins and inorganic salts, will also be dissolved in water, and the nutritional value will be reduced. If the kelp is not as tough as if it has been boiled after being soaked in water, it means that it has deteriorated and can no longer be eaten.

Traditional Chinese medicine believes that people with kelp cold, spleen and stomach deficiency and cold should avoid eating.

3.Don't drink tea immediately after eating kelp, and don't eat sour fruits right away, because kelp is rich in iron, both of which can hinder the absorption of iron in the body.

From the above introduction, we know that kelp can still be eaten after a long time, but the premise is that the soaked kelp needs to be put in the refrigerator, if it is dried kelp, then there are not so many requirements, and the trace elements of kelp are still more, and occasional consumption is good for the body, but it cannot be eaten as a staple food for a long time. Maintain a good diet.
