Fresh white fungus is poisonous is a rumor and cannot be trusted.

Through research and literature search, it was found that the assertion that "fresh tremella is toxic and contains porphyrins, which can cause solar dermatitis" lacks scientific basis. So far, there has been no research literature and related testing evidence for the presence of porphyrins in Tremella fuciformis, and there have been no case reports of solar dermatitis caused by the use of fresh Tremella.

Porphyria is a porphyrin metabolism disorder caused by the lack of a certain enzyme or reduced enzyme activity in the heme synthesis pathway. Foodborne porphyria occurs only if the body's porphyrin metabolism is abnormal.

The three elements required for the onset of solar dermatitis are ingestion of photosensitizing substances, prolonged sun exposure, and abnormal porphyrin metabolism (the patient's constitution). Not all solar dermatitis is caused by porphyrins, and not all porphyrins cause solar dermatitis.

In short, people with normal physique can use fresh white fungus with confidence.

Not all of them are poisonous, but fresh white fungus is easily contaminated by coconut monas methyl to produce rice fermented acid, once poisoned, there is no cure but to resign to fate. It's the same as sour soup poisoning. Although the probability is low, the mortality rate is high.

In the supermarket, the bulk snowflake dried white fungus is a catty, and the fresh white fungus is a yuan, one weighs about 100 grams, and it is about 68 yuan per catty, and the price of the two is about the same. In addition to offline sales, online sales of fresh white fungus are also good. Fresh white fungus is easy to carry the toxin of the virus rice fermented acid, causing organ failure, and what is more terrible is that there is no special antidote to the toxin, so you can only take first aid measures such as intestinal lavage and vomiting, and the mortality rate is very high.

Many consumers said in their reviews that fresh white fungus has a softer and waxier taste than dried white fungus. Is fresh white fungus worth buying than dried white fungus? Lun nutrition is not as dry as fresh, white fungus in the process of dry production?

A certain sterilization and disinfection effect, and a small amount of pollution in time is also reduced by ultraviolet irradiation. Buy dried white fungus should also pay attention to a look, high-quality white fungus is relatively dry, the color of the ear piece is golden yellow, shiny, the flower is generally light and loose, the flesh is thick, tough and elastic, the pedicle has no ears and feet, black spots, no impurities, etc. Dried white tremella is white and may have been smoked with sulfur.

The second touch, fresh white fungus is relatively dry and brittle to the touch, a little prickly. Three-smelling, fresh white fungus, no sour odor and other peculiar smells. Four boiled, good white fungus quality is pure, boiled and melted, sweet and glutinous.

The fresh white fungus sold in the market is processed and is not poisonous. Wild white fungus contains certain toxins. Real fresh Tremella, that is, freshly picked and unprocessed, is a porphyrin photosensitive substance, after eating fresh Tremella, porphyrin photosensitive substances will be distributed into human epidermal cells with blood circulation.

Exposure to the sun at this time may cause solar dermatitis.

Redness, swelling, itching, bright red papules and blisters appear.

Porphyrin photoreceptors are also easily absorbed by the throat mucosa, resulting in throat edema, general malaise, and runny nose.

Symptoms such as watery eyes, fatigue and shortness of breath.

For fresh white fungus, it is recommended not to buy or eat it, not because it must be poisonous, but because it is not necessary.

First of all, dried white fungus retains most of the nutrients in white fungus, including polysaccharides, vitamins, minerals, etc., and fresh white fungus is not much better than dried white fungus. Secondly, during the drying process of white fungus, even if there is a small amount of toxin pollution, it will be degraded a lot under the action of sunlight and ultraviolet rays. The data showed that the detection rate of rice fermented acid in fresh tremella was much greater than that of dried tremella, and there was no poisoning of dried tremella at present.

Key points for the selection of dried and fresh white fungus.

Fresh white fungus should be pure white to milky white, translucent, and elastic; Dried white fungus is hard and brittle, beige or golden yellow in color. If the dried white fungus is too white, it may be smoked with sulfur.
