Tremella, also known as tremella, is of high quality. Known as the "crown among bacteria", it is not only a valuable nutritional supplement, but also a tonic for strengthening the body. Many people like to eat. However, it is reported that eating tremella and auricularia can actually lead to food poisoning. Is it true?/You don't say. /You don't say.

Causes of food poisoning

Tremella can be divided into dried tremella and fresh tremella. Some people think that fresh tremella is fresh and has high nutritional value, but it is fresh tremella that causes food poisoning. Due to the influence of cultivation environment and soil, fresh tremella will produce a kind of bacteria called Pseudomonas cocoanum. The growth temperature of this strain is 25-37℃, the optimum growth temperature is 37℃, and the optimum toxin production temperature is 26℃. The toxin produced is called' rice fermented acid', and its poisoning incubation period is as long as 3 days, mostly half a day to one day. This toxin is heat-resistant and cannot be removed by washing or blanching. Its symptoms are the same as mushroom poisoning. General symptoms first appear in stomach discomfort, nausea and vomiting, abdominal distension and abdominal pain. Then toxic hepatitis, renal failure and other clinical manifestations, such as hepatomegaly, abnormal liver function, severe liver coma and even death. Besides fresh tremella, other fermented corn flour products and other modified starch products have been proved to produce kojic acid. Therefore, it is necessary to stay away from "fresh" tremella to prevent poisoning of deteriorated fresh tremella.

How to Choose and Eat Tremella fuciformis

1. Tremella fuciformis is generally chrysanthemum-shaped or chicken-shaped, and consists of 10 thin and wrinkled bacterial slices.

2. Tremella is hard and crisp, and it is beige or golden yellow. If the dried tremella is too white, it may be illegally smoked with sulfur.

3. After soaking in water, dried tremella should have a complete flower shape, white or yellow fungus blocks, good elasticity and no peculiar smell. If bacterial fragments are found to be dark yellow to yellowish brown, shapeless, sticky, inelastic and smelly, they should be discarded and not eaten.

4. Wash the tremella thoroughly and remove the brown part of the tremella root.

5. Tremella should be fully heated and cooked.

Recently, it was reported that a family of three in Zhejiang ate black fungus soaked for two days, which led to food poisoning. After testing, it was found that there was yeast acidotoxin in the blood of the patient. However, the remaining dry fungus in the patient's home was soaked for five days, and no fenamic acid was detected! At present, it has been proved that rice fermentation acid can exist in modified starch products such as deteriorated fermented corn flour products and deteriorated fresh tremella, but so far there is no experiment to prove that this toxin exists in normal dry auricularia or long auricularia. So, where did the kojic acid in this case come from? This is still a mystery. According to most people's inference, other expired foods were soaked in auricularia auricula, which led to a large number of bacteria in auricularia auricula, and finally rice kojic acid appeared. Aside from the causes of kojic acid production, it is at least certain that fungi such as auricularia auricula and tremella are easy to deteriorate and breed harmful bacteria, thus causing food poisoning. Therefore, it is necessary to develop good kitchen hygiene habits, clean cookware, tableware and dishcloth in time, properly refrigerate food that is easy to deteriorate at room temperature, and know how to discard expired food.

First, soak the ingredients such as fungus and eat them when they are delivered, especially in summer. You'd better soak the fungus in the refrigerator. Second, I forgot to change the water after soaking for a long time, which was sticky and smelly. Don't be reluctant to throw it. There are fresh auricularia auricula in the market at present. Consumers should choose carefully. If it is sticky, flowing or smelly, they shouldn't eat it. If you feel unwell, you should seek medical advice as soon as possible and inform the doctor of your diet history. Fresh tremella is not recommended. Fourth, separate raw and cooked chopping boards, thoroughly cook ingredients, control storage time, and pay attention to hand disinfection and hygiene.
