How to wash the kelp to be clean, how to wash the kelp to be clean

Kelp is now a very common food, and it is served as an appetizer for occasions such as dinner parties and wedding banquets. But how to make it yourself, and how to make it convenient, simple and clean? In fact, the cleaning of kelp is more troublesome, and you can master the cleaning method.

1. How to wash kelp?

For a quick wash, soak the dried kombu in warm water and after a few moments, scrub the dirt off with your hands (don't push too hard). Rub it a few times, change the water a few times, and it will be washed off quickly.

Dried kelp is kombu. Kelp is known as "longevity vegetable", "sea vegetable", and "iodine-containing champion", and from the perspective of nutritional value, it is a kind of food for health and longevity. 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.

Generally, the kelp we buy is sun-dried, and these kelp are not treated after being salvaged from the water, so there is a lot of dirt on them. Therefore, you should first soak the kelp in warm water, preferably half an hour in advance.

Second, the foaming method.

1. If you use dried kelp, you should rinse the surface of the kelp, then put it in a steamer and steam it for 30 minutes, then soak it in water overnight before using it for cooking to make it crispy. Do not soak the kombu directly, otherwise it will have a hard texture no matter whether it is stewed or stir-fried.

2. When cooking with kelp, whether it is stewed or stir-fried, add some vinegar to make the taste better.

3. There is a layer of hoarfrost on the surface of dried kelp, which is a substance called mannitol formed by the weathering of plant alkali, which is not only harmless, but also has the effect of detoxification and swelling. Don't mistake that hoarfrost for salt precipitation, or mold and deterioration.

4. There is a layer of mucus on the surface of kelp, so it does not need to be washed excessively, in that case, a lot of nutrients will be lost.

The above are all my own findings about how to clean kelp related introduction, after reading I believe you will also clean kelp, but kelp is particularly hard, not easy to digest in the stomach, especially friends with bad stomach, it is best not to eat too much at a time when eating, too much will increase the burden on the stomach, it is best not to choose to eat at night.

Dried kelp] Dried kelp often has a layer of white powder like hoarfrost attached to it, and it feels unclean. In fact, this layer of white powder is not mold, but an organic compound "mannitol", which is a precious medicinal substance that has the effect of lowering blood pressure, diuresis and swelling. If the dried kelp is soaked in water for more than a few hours, about 90% of iohexanic acid will be lost, and mannitol will also be dissolved, which reduces the nutritional value of kelp.

Therefore, soak the newly purchased dried kelp in water for about 6 hours, and then scrub it by hand to remove the fine sand and mucus attached to the kelp. The soaking time should not be too long, otherwise the nutrients in the kelp will dissolve in the water, causing nutrient loss.

Nowadays, due to the increasing pollution of seawater, seafood will absorb some harmful substances to a greater or lesser extent, generally arsenic and arsenide. Therefore, from a safety point of view, it is important to wash the kelp when it is eaten, as the arsenic and arsenide will dissolve in the water after the kelp is soaked in water. Therefore, when soaking kelp, the amount of water should be sufficient, and the water should be changed during the soaking process.

Therefore, under normal circumstances, fresh kelp can be soaked in water for about 5 hours, and the water can be changed several times in the middle. If you buy a kelp knot, you need to open the kelp knot and clean the sediment inside. If soaked for too long, the nutrients contained in kelp, such as inorganic salts and water-soluble vitamins, will dissolve in water, resulting in a decrease in the nutritional value of kelp.

1. Wash off the salt and soil on the dried kelp with an old toothbrush, and then soak it in clean water. After about ten minutes, the kelp will gradually grow, and then rub and rinse it at this time, so that it is clean, but for the sake of health, it is best to change the water soak several times to reduce the arsenic content in the kelp.

3. Soak the dried kelp in rice washing water, the boiled kelp is delicious and soft.

4. Adding some alkali or vinegar when boiling kelp can make the kelp soft quickly and is conducive to iodine absorption.

5. There is a layer of hoarfrost (mannitol) on the surface of dried kelp, which is the mucus on the surface of kelp, which is rich in nutrients and has the effect of detoxification and swelling, and does not need to be over-cleaned.

1. Use an old toothbrush to wash off the salt and soil from the dried kelp, and then soak it in water. After about ten minutes, the kelp will gradually expand. At this time, rub and rinse it so that it is very clean.

However, for the sake of health, it is best to change the water and soak it several times to reduce the arsenic content in the kelp.

There are several ways to wash kelp: hot water soaking, brushing.

1. Hot water bubbles.

Soaking kelp is the first step in cleaning kelp, kelp is generally salvaged from the sea, there are not only a lot of dry dirty things on it, these things are yellow or gray-black, if it is difficult to deal with it directly, so it is generally moistened and soft with water first, in order to make the stains soft faster and more thorough, it is best to soak in hot water for half an hour.

2. Brush brush.

The purpose of brushing with a brush is to better remove the dirt, usually if you have washed kelp, you know that the surface of kelp will produce a very slippery film, it is difficult to wash it by hand, but if you use a brush, rub it back and forth with the brush head, it will be much simpler, because it has been soaked in water.

How to buy kelp:

1. When buying kelp, it is best to open the kelp roll yourself to see if the kelp is well preserved, and carefully observe whether the kelp leaves are solid. If you find that the kelp is small and the leaves are not intact and there are many broken leaves, then do not buy it.

2. Look at whether there are small holes on the kelp, or a large area of damage, if there is, it means that the kelp has been eaten by insects or moldy deterioration during long-term storage.

3. There is a layer of white powder on the surface of kelp, which is an important sign of good kelp, if there is no such layer, then it means that the quality of kelp is not high, and it may be the previous inventory. It is recommended that you do not buy it.

4. When choosing dried kelp, first look at whether the surface is white powder, because kelp is the food with the highest iodine content.

5. The thickness of the kelp should be thick, and the large one is better.

The way to wash kombu is as follows:

Put the fresh kelp in clean water and rinse both sides slightly, rinse the sediment on the surface of the kelp, then put it in a container, add some starch to it, stir well, leave it for two or three minutes, wait until the time is up, rub it with your hands, and finally rinse off the starch with water, so that it is relatively clean.

If it's dried kelp, use an old toothbrush to quickly brush off the salt frost and sediment on it. Then before washing, you need to put it on the steamer drawer and steam it dry for 20 to 30 minutes, put the steamed kelp into clean water, add a spoonful of flour or starch, and wash it according to the above ordinary kelp washing method.

Nutritional value of kelp:

Kelp is a vegetable with high nutritional value, each 100 grams of dried kelp contains: crude protein grams, fat grams, sugar 57 grams, crude fiber grams, inorganic salt grams, calcium grams, iron grams, and carotene mg, thiamine (vitamin B1) mg, riboflavin (vitamin B2) mg, niacin 16 mg, can produce 262 kcal. Compared with spinach and rape, in addition to vitamin C, its crude protein, sugar, calcium, and iron content are several times and dozens of times higher.

Kelp is a seaweed with a high iodine content, generally containing 3 5 iodine and up to 7 10. The iodine and alginic acid extracted from it can be used in medicine, food and chemical industry.

Raw materials: kelp, rice washing water1. Step 1: Soak in warm water and then wash with rice washing water to effectively remove mucus.

Kelp is rich in iodine and has a fresh taste, so it is loved by many friends. But the question that bothers many friends is, how to wash the kelp cleanest? You need to know a little bit about kelp!

First of all, it is necessary to find out whether kelp contains "arsenic".Arsenic, in nature is commonly found in the environment and plants, animals, aquatic organisms, especially marine organisms, have a strong enrichment ability of arsenic, generally marine fish contain arsenic milligram kilograms, lobster 70 milligrams kilograms, kelp 35-40 milligrams kilograms, of course, different sea areas of their pollution degree is different, arsenic content is also different. Elemental arsenic is not toxic, arsenic compounds such as oxides, salts and organic compounds are.

Arsenic is a trace element in the body and plays a certain role in the metabolism of human cells, but long-term excessive intake can cause chronic poisoning. Arsenic in the human body is mainly in the form of arsenic acid, which is mainly excreted through the kidneys and intestines. The amount of arsenic in the blood of a normal person is 100 milliliters, and the amount of arsenic in the urine is milligrams.

The World Health Organization has established a provisional maximum allowable intake of arsenic in milligrams of daily kilograms of body weight. Arsenic contamination of food is often caused by: contamination by industrial hazardous substances; contamination with pesticides containing arsenic; contamination during food processing; contamination of containers, etc.

The arsenic content of kelp is mainly caused by seawater pollution. Therefore, when eating kelp, from a safety point of view, be sure to wash it, after the kelp is soaked in water, arsenic and arsenide dissolve in water, and the arsenic content will be greatly reduced. When soaking, use more water, or change it.

The first and second water, as for the soaking time, it is not easy to say absolutely, which has a lot to do with the texture and arsenic content of kelp, and the soaking time of kelp is relatively tender and contains less arsenic can not be too long; If the texture is hard and contains more arsenic, the soaking time can be relatively long, but because the amount of arsenic is difficult to identify with the naked eye, it is generally said that soaking for about 6 hours is enough, because 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. How do you wash kelp cleanest? Now you know!

Next time you wash kelp, you won't have to worry!

Washing kombu is difficult to wash with only clean water! Put a little thing in the water, and the dirty thing will fall off immediately.

Steam in a pot for 20 minutes and then wash the kelp, so that the nutrients in the kelp will not be lost.

It is said that the kombu is soaked in rice washing water for a while, and then washed to wash it well, and the dirt is washed down immediately.
