Friendly reminder: Cherish life and stay away from fresh Tremella

In the dessert world, Tremella and lotus seed soup and papaya stewed with Tremella definitely have a place.

The soft and sticky white fungus is nutritious and delicious. It is great for making desserts, soups, and cold dishes.

To be honest, Tremella fuciformis is an edible fungus that is very rich in nutrients. It not only contains protein, polysaccharides, dietary fiber, but also a variety of vitamins and minerals.

However, most of the common white fungus on the market are dried, while fresh white fungus has quietly become popular in the past two years.

Fresh Tremella real picture

I opened some grocery shopping apps and found that many platforms were selling fresh white fungus.

There are also many shops selling fresh Tremella fuciformis on a certain shopping platform.

According to the merchants’ propaganda, these fresh white fungi [are not fumigated with sulfur], [do not need to be soaked], [are easy to produce gelatin], and [have higher nutritional value].

In fact, properly soaked dried white fungus not only tastes the same as fresh white fungus, but also has similar nutrition.

However, fresh Tremella fuciformis is easily infected with Pseudomonas cocovenenans due to the influence of the cultivation environment and soil.

This fungus produces a highly toxic toxin, fumonisin, which makes the headlines almost every year in a tragic way.

The toxin fumonisin is extremely toxic . The incubation period of poisoning is generally 2 to 24 hours. Symptoms of the digestive tract and nervous system will first appear. In severe cases, death may occur due to multiple organ failure such as liver, brain, and kidney.

The most powerful thing is that even if it is heated at 120℃ for 1 hour, it can still maintain its toxicity, so don't think about removing the toxins by heating.

During the production process of dried Tremella fuciformis, the toxin aflatoxin will be degraded through exposure to sunlight. This is why there has been no incident of poisoning from eating dried Tremella fuciformis.

As early as 2017, the State Food and Drug Administration reminded us to be careful when eating fresh Tremella fuciformis.

By 2018, the State Administration for Market Regulation once again reminded that it is prohibited to eat self-picked fresh white fungus and fresh black fungus.

Summer and autumn are seasons that are prone to food poisoning, so we should be especially vigilant.

There is really no need to eat fresh white fungus, but remember to eat dried white fungus and black fungus on the day they are soaked, do not leave them overnight.

In addition to black fungus and white fungus, these foods are also easily contaminated by Pseudomonas cocovenenans in the environment and produce fumonisin toxins if stored for too long, so we should also be careful.

Fermented cereal products: wet rice noodles, rice noodles, fermented corn flour, glutinous corn glutinous rice ball flour, corn starch, fermented glutinous millet, hanging rice cakes, glutinous rice cakes, vinegar jelly, etc.

Potato products: potato vermicelli, sweet potato noodles, taro starch, etc.

Tremella soup is delicious, but don't touch fresh Tremella, after all, life is the most important~
