How to preserve killed yellow eels

Eel is a food with relatively good nutritional effects. Generally speaking, after killing the eel, it can be stored at room temperature for up to 12 hours. If the weather is hot, it may even deteriorate in a short time. Therefore, when buying eels, it is best to kill and eat them immediately. The slaughtered eels can be placed in the refrigerator and can be kept for up to one day. Let us learn how to preserve the killed eels.

How to preserve killed eels

If you want to preserve the killed eels for a long time, you must freeze them in the refrigerator. Once a fresh eel dies, the histidine in its body will quickly decompose into toxic histamine. The longer the eel has been dead, the more toxic it contains. It is best to store any eels that cannot be eaten in the refrigerator.

How to preserve live eels: Place live eels in a bucket or basin (the amount should be controlled), with the amount of water enough to cover the eels (it can exceed a little), and then place in a cool place. If the bucket or wooden basin containing the eels is too short, please add a ventilated lid to prevent them from escaping. If the storage time is long, please change the water regularly and add some egg white to the water to maintain its nutrition.

Is it better to refrigerate or freeze the eel after killing it?

1. Place in the freezer.

Eel contains a large amount of nutrients. Once the eel dies, its body will quickly decompose toxic and harmful substances. The longer the eel has been dead, the faster the decay process and the greater the toxic side effects of eating the eel. Even if placed in the refrigerator, it will quickly deteriorate. Only by placing the eel in the freezer of the refrigerator can the decomposition of the eel cells be temporarily stopped and the eel's decay process be paused.

2. Can dead eels still be eaten?

It depends on the specific situation. If it has just been slaughtered, it can naturally be eaten if it has just died. The eel has just died, and the toxic and harmful substances in its body are not very rich. Eating it will not have a big effect on the body. Eating it at this time will not cause any harm to the body. If you don’t eat it at this time, it will become inedible after a period of time. It is recommended to eat it as soon as possible.

Because the eel's body contains more histidine and trimethylamine oxide after death, the histidine in its body will decompose into toxic histamine. Moreover, eel is a high-protein food. Once it dies, the bacteria and toxins in its body will begin to multiply rapidly. The longer the time since death, the more toxins accumulate. It would be counterproductive to eat eels with toxic side effects and cause poisoning.
