Auricularia auricula itself is not toxic, but "Pseudomonas cocoanum" may be produced during the foaming process of dried auricularia auricula.

When soaking auricularia auricula, keep it clean and low temperature, and control the time. Soak in cold water for 2 hours at room temperature, and soak in refrigerator for 4 hours.

Auricularia auricula is nutritious, but it can't prevent and cure diseases. Every year, when it comes to the season of eating cold fungus, you will always see the news of eating fungus liver poisoning. Severe poisoning symptoms and serious consequences:

Vomiting, unconsciousness, jaundice, hepatomegaly, subcutaneous hemorrhage, hematemesis, convulsion, convulsion, shock, organ failure ... The mortality rate is 40%- 100%, and there is no specific antidote.

The culprit of poisoning is Pseudomonas cocoanum and its metabolite "mycotoxin", which grow wildly during the process of soaking auricularia auricula.

This toxin is very heat-resistant and cannot be removed by high-temperature cooking. Even if it is ingested in a small amount and slightly poisoned, symptoms such as fatigue, diarrhea and vomiting may occur. The incubation period of poisoning is usually from half an hour to 12 hours, or as long as 3 days. If these symptoms appear after eating auricularia auricula, you should be vigilant and seek medical advice in time.

In fact, auricularia itself is toxin-free, and it is the warm and oxygen-free environment that leads to the growth of bacteria during the process of soaking dried auricularia. The nutritional components of auricularia auricula provide sufficient nutrients for bacteria.

To avoid poisoning, the key is to pay attention to food safety and cooking hygiene, and not to provide a breeding environment for bacteria.

How to soak fungus is safe?

Ensure cleanliness

First of all, rinse the dried fungus before soaking it.

It is also necessary to ensure the cleanliness of the container and the surrounding environment, and ensure that there are no residues of other foods in the container and no other spoiled foods around. The water for soaking fungus should also be kept clean and clear.

notice the time

Soak the auricularia auricula in cold water for 1-2 hours, and it can be eaten, and the maximum time is no more than 4 hours. It is not recommended to soak it overnight.

temperature

The optimum growth temperature of Pseudomonas cocoanum is 37℃, and the optimum toxin production temperature is 26℃. [6]

Now the weather is getting hotter and hotter. If the room temperature in your area is already very high (more than 20℃), or if you can't handle it within 2 hours after soaking Auricularia auricula1-,you can put it in the freezer and soak it in the freezer for 3-4 hours.

Give up in time

If you smell the smell or feel sticky when checking the soaked fungus, it is more important to discard the fungus decisively to save your life. Don't soak too much at a time, which is more likely to happen when you can't finish eating and soak for a long time.

What should I do if the fungus is soaked too much?

The soaked auricularia auricula can be stored in a fresh-keeping bag for one or two days after being drained. If it needs to be stored for longer, consider freezing.

If it is cooked and seasoned auricularia auricula, considering that it is difficult to absorb water at this time, it should be put in the refrigerator as soon as possible, and it should not exceed 24 hours under cold storage conditions.

Not only soaked fungus, but also soaked tremella, mushrooms, bean skin, yuba and other dry goods also need attention.
