The shelf life of dried kelp can generally be stored for about a year. It is also analyzed according to the place of storage, if it is placed in a cool and dry place, the storage time may be longer, if it is a humid place, it will go bad in less than a year, and it is also important to store it correctly. When eating kelp, it should be cleaned and soaked in water according to the actual situation, and the water should be changed continuously, generally soaking for more than 6 hours.

Key Value: For consumption. The protein of kelp has a complete range of amino acids and appropriate proportions, especially the eight essential amino acids, and its content is very close to the content pattern of essential amino acids in the ideal protein.

In addition to being used as a dish, kombu can also be processed into a variety of foods with unique flavors.

For feeding. Adding kelp powder to the feed can effectively improve the nutritional structure, reduce the cost of feeding, increase body weight, improve egg production rate, reduce mortality, and improve the quality of breeding varieties.

As industrial raw materials, fucoidan, mannitol, dietary fiber and sodium alginate in kelp are extracted.

1.The first, if it is dried kelp, it is not moldy and spoiled, and it can be eaten. If there are signs of mildew, it is recommended not to consume it again to avoid health hazards.

How to preserve dried kelp:

After we buy dried or fresh kelp, if we unpack it, we need to put it in the refrigerator as soon as possible. This is because kelp itself is relatively difficult to preserve.

When unpacked, dried kelp comes into contact with many components in the air, as well as sunlight. Some of its own substances may change slowly, which is a loss of nutrients.

In addition to this, bacteria may also grow. As harmful substances and microorganisms increase, the kelp in the air deteriorates little by little. So the best way is to store the dried kelp in the refrigerator.

How to store dried kelp.

So, how long exactly can regular dried kelp last? If you keep the unopened dried kelp in the refrigerator, it can theoretically be stored for up to half a year. In contrast, the shelf life of dried kelp.

It's a lot longer than fresh kelp. However, if the dried kelp has been opened, it needs to be eaten in time. Or reseal.

Overall, dried kelp lasts much longer than regular fresh kelp. Normal light-dried kelp can be stored in the refrigerator for up to half a year. However, both dried and fresh kelp should be kept in the refrigerator and should not be simply placed in a dry and cool place.

First of all, after the dried kelp is bought, the kelp should be completely dried (it can be broken by hand), packed in a plastic bag, tied tightly, and paid attention to moisture, so that it can be stored at room temperature for more than a year.

Secondly, if it is kelp that has been soaked, it should be consumed as soon as possible. If it cannot be consumed, wash it and put it in a safe bag to freeze. Be sure to keep it in the refrigerator, otherwise it will affect the quality and taste.

Dried kelp can be stored for about half a year to about 1 year at most.

If the dried kelp is stored at room temperature, it can generally be stored for about half a year, and if the dried kelp is stored in the freezer of the refrigerator, it can generally be stored for about a year, but the dried kelp needs to be wrapped in plastic wrap before refreezing to avoid moisture.

Kelp is rich in kelp polysaccharides, and three kinds of polysaccharides have been found so far: algin, fucoidan, and fucoidan. It also contains acidic glycans, fucogalactopolysaccharide sulfate, macrophyllin, galacturonic acid, kombunine, taurine, bifidus and other active ingredients.

Kelp is a nutritious edible brown algae that contains more than 60 nutrients.

Dry kelp can be soaked in cold water for about 30 minutes, wash off the dirt on the surface of the kelp and change the water before soaking, and then change the water blister for 20 minutes every 20 minutes, but it depends on the quality of the kelp, if the kelp meat is thick and hard for a longer time, it doesn't matter, otherwise, the time is shorter.

After soaking in water for 5 to 10 hours, the arsenic content of dried kelp is still as high as 5 mg/kg. After soaking in water for 24 hours, the arsenic content can meet the food safety standard. Therefore, it is best to soak dried kelp for a longer time before consuming it.

Precautions for soaking dried kelp

If the soaked kelp is soft, as if it is boiled, it means that the kelp has deteriorated and can no longer be eaten.

Soak the kelp in rice water, or add a little edible alkali or baking soda when boiling the kelp, but not too much, soak the kelp in cold water after boiling soft, wash it, and then remove it to eat.

Generally, it can be stored for about a year, but depending on the area you are in, if you are wet for a long time or if you have not put the dried kelp in a cool and dry place, it will not be stored for a long time, if you are from an arid area, it may be stored for a longer time.

However, it is better to eat the things you buy earlier, because it is healthier to eat fresh things than to eat things that have been eaten for a long time.
