Can I still eat the seaweed I bought in the supermarket when the soup is red?

Seaweed is red, put it in water to see if it will fade, and then taste it to see if it has changed its taste, if it doesn't, you can eat it. I've also bought redness before.

The preservation of laver requires constant temperature and humidity conditions, generally laver is stored in cold storage before leaving the factory, and the cold storage conditions of large enterprises are better, under the condition of constant bottom temperature, the softness of laver will change, and the taste will become better. The most important thing for the preservation of laver products in supermarkets is to store them in dry conditions, if they are not stored well, or if the sealed packaging has air leakage, it will cause moisture in the air to enter, resulting in mold. If the seaweed is mildly moldy, it may not be visible and there will be redness.

If the nori is already red, it is generally not recommended to eat it. Because mold can produce toxins that can affect health. If you have to eat it, you need to rinse it carefully to remove some of the mold, if the seaweed is seriously moldy, it will often rot when rinsing, so don't eat it again at this time.

If the seaweed has been slightly red, it should be heated thoroughly and fully cooked before eating, but the nutritional value and taste of the seaweed at this time will be greatly reduced. When buying seaweed, pay attention to choosing a good package to see if there is air leakage and whether the color is normal. Some manufacturers have a little mildew in the raw materials at the beginning, and it is not good to seal the laver in packaging.

It is recommended to check the tightness of the packaging when buying, whether the trademark of the product is complete, and do not buy too cheap three-no products. There are quite a lot of introductions to the knowledge of laver in Wanzihui, and there are all laver products, but they are all large wholesalers, and the average family still buys them in regular supermarkets.

Seaweed is a kind of seafood, and we usually use seaweed to make egg drop soup to drink, which can also supplement iodine. We will soak the seaweed before eating, and if the water of the seaweed changes a little when the cold water is soaked, then it is normal. However, if the color still fades after soaking in hot water, you should be careful to buy dyed seaweed.

Let's learn more.

Seaweed soaked in water will fade, but to a very low degree. If the seaweed is soaked in water and decolorized severely, you should be careful whether it is dyed seaweed. Nori usually contains the natural pigment phycoerythrin.

Phycoerythrin is usually found in algae plants, and its role is to capture and absorb light energy and transfer light energy to chlorophyll. As a result, nori can live in deep water, and some can also survive at depths above 100 meters. The reason why nori fades after foaming is precisely due to the presence of phycoerythrin.

Since this pigment is soluble in water, it is normal for the color to fade during the foaming process.

This situation is not normal, so be careful if it is dyed seaweed. Seaweed contains phycoerythrin, which will decolor a little if soaked in cold water, but it will not change color with hot water. Because phycoerythrin is a protein that denatures when heated, soaking it in hot water, including the nori soup we usually cook, does not appear red.

If it appears red, it may be dyed seaweed, and you can blanch it with boiling water with unprocessed seaweed. If it is stained with artificial colors, it is usually chemically stable, and the water will remain red when boiled.

Usually, nori has a shelf life of 3-6 months. Nori is a type of seafood that regenerates and spoils easily. Therefore, before eating the nori, you can put the leftover nori in a black food bag and put it in a low-temperature dry place.

It can also be stored directly in the refrigerator to maintain its original quality and nutrition. Before eating, we first soak the nori in clean water and then change the water once or twice to remove small impurities.

It is normal for seaweed to have a little red, but when the redness is more severe, it may produce toxins that are harmful to the human body. People who are deficient in calcium should be cautious when eating laver, because laver will affect the body's absorption of calcium and will have a certain impact on human health.

Whether the seaweed turns red or not depends on the specific situation, because it is normal for the seaweed to have some redness, but when the seaweed is more red, it is not recommended to continue to eat, because this seaweed may produce toxins.

When eating seaweed, it is necessary to pay attention to the fact that people who lack calcium should eat less seaweed, because seaweed will affect the body's absorption of calcium, and human health will also be affected.
