Oryzanol is a toxin that can cause food poisoning. Mainly produced in fermented corn flour products, deteriorated fresh tremella, fungus and other foods. Of course, there are glutinous rice noodles, glutinous rice balls, potato vermicelli, sweet potato starch and so on. All contain this kind of bacteria, so this kind of food must not be used after deterioration.
Once fresh tremella goes bad, it is easy to produce rice yeast acid, which causes food poisoning.
The sour soup ingredients in this incident were seriously polluted by Aspergillus flavus, and this mold will not exist alone.
In other words, food raw materials may also be contaminated by other microorganisms at the same time, among which Pseudomonas cocoanum may exist.
Once the fermented product is contaminated by mold in the fermentation process, it will produce toxins. No matter how long it is stored, it is very likely to be poisoned when eaten.
How to prevent "rice fermentation acid" poisoning?
First, homemade grain fermented food. Do not use moldy corn and other raw materials; Change the water frequently when making cereal, and smell it before using it. When all kinds of ground grain are stored separately, it should be ventilated and moisture-proof, maintain hygiene and prevent pollution.
Second, fungus or tremella. Clean it first, then soak it in water and containers or cook it. Don't use too much at a time, and eat it in time after soaking. If you choose a cold salad, you must first blanch it with boiling water, and then add garlic and vinegar appropriately. Don't eat fresh tremella or fungus picked by yourself, especially deteriorated tremella or fungus. In addition, there are fresh black fungus on the market at present, so you should choose it carefully. If it is sticky, flowing water or smelly, you must never eat it. If you feel unwell, you should see a doctor as soon as possible and tell the doctor about your eating history.
Third, grain fermented products. It is easy to produce this toxin if the grain fermented products are stored improperly or for a long time. It can still cause food poisoning after heating, and it is usually eaten on the day of purchase.
