Introduction: When it comes to aflatoxin, many people may not know what this is? Aflatoxin has been classified by the World Health Organization as the most potent carcinogen of Category 1; its toxicity is 10 times that of highly toxic potassium cyanide and 68 times that of arsenic, but aflatoxin is hidden in several of our regular foods. Food...
20 hours at 100°C also kills carcinogens
The optimum temperature for the growth of Aspergillus flavus is 26°C~28°C. The higher the temperature, the faster the growth of Aspergillus flavus, and once the temperature is 25°C~32°C and the relative humidity is 80%~90%, Aspergillus flavus Can quickly secrete toxins. Therefore, this toxin is suitable to survive in the high temperature and very humid south.
Aflatoxin is very stable, it is difficult to kill it in general temperature, not easy to dissolve in water, the general cooking process can not be destroyed, that is, the use of high temperature 100 °C for 20 hours of sterilization, can not be Remove it completely.
Mouldy food contains aflatoxin
- Found that moldy peanuts, the best package to throw away
Aflatoxin is most liked to be hidden in moldy foods, especially foods with high starch content. Peanuts are no exception. In hot and humid environment, it is most likely to breed this carcinogen.
Recommendation: Even if there is only one peanut mold, the whole package of peanuts must be thrown away. Aspergillus flavus is spread in the form of spores, and food can easily be implicated in mildew.

- Tasteful nuts
If you eat a bitter taste of the seeds, almonds and other nuts, must be promptly spit and gargle. Because of the bitter taste of nuts such as seeds, it is the aflatoxin produced during the mildew process. Frequent ingestion increases the risk of liver cancer.
Recommendation: Always eat mildewed nut snacks must not be lazy, to get up spit up and then rinse with clean water.
- Fungus soaked for a few days
There has been such news: A consumer of Zhejiang Ruian caused food poisoning by eating black fungus soaked for three days, resulting in multiple organ failure and dying life.
The diagnosis given by the doctor: This is a serious consequence of the microbial toxin. Fungus foaming in the water for a long time, will produce aflatoxin, penicillin and so on.
Suggestions: How many bubbles eat fungus, do not soak for several days.

- Uncleaned chopsticks
The chopsticks themselves are not likely to grow as Aspergillus flavus, but when chopsticks are used to eat foods with a high starch content, such as corn and peanuts, the chopsticks can contain starch. A long time leads to mildew, bare chopsticks, lacquer chopsticks, and food residues that can easily dehisce, and aflatoxins are produced.
Advice: Wash before soaking, soften the food residue above, drain it after washing, and dry it in a dry and ventilated place.
The chopsticks must be placed facing up and the cutting board can be hung or raised. Do not place it on a wall or place it on a countertop. It is best to rinse it with running water before each use.

- Moldy corn
Aflatoxins are hidden in moldy foods, especially peanuts, corn, beans, and other foods with high starch content. Starch can breed aflatoxins that cause liver cancer in hot and humid environments.
Suggest:
1, buy less every time, do not "save" in order to avoid mildew.
- It is best to throw away rice and corn suspected of having aflatoxin on the surface.

In general, small-scale presses or household oil presses have simple processes. They do not remove harmful substances and can not refine the raw materials. Therefore, peanuts with normal appearance and internal aflatoxin appear to be difficult to pick out. The raw material is moldy, and the extracted oil will also contain aflatoxin.
Recommendation: Go to the supermarket to buy regular well-known brands of cooking oil.

Many people would say that if I cook the food in the pot for a while, I will not be able to "sterilize" it.
However, the normal cooking temperature cannot destroy aflatoxin because the aflatoxin cleavage temperature is 280°C. Only when it reaches a temperature of 280°C can it be completely eliminated. The general method of cooking is to eliminate aflatoxin without hair, and aflatoxin is also very resistant to UV rays.
A little trick before cooking to help you eliminate a certain amount of aflatoxin
1, oil heat, first add salt
We put peanut oil and other edible oils into a pan and heat it, and put a small amount of salt, stirring for 10 to 20 seconds, so that we can eliminate aflatoxins in most edible oils. Because salt has very good neutralization and degradation of aflatoxin, it can probably eliminate 95% of aflatoxin.
2, eat more green leafy vegetables
Eat more green leafy vegetables, because the chlorophyll in vegetables can prevent the absorption of aflatoxin and prevent liver cancer.

3, try not to hoard food
The most effective way to avoid aflatoxins is to cut off the source and prevent food from producing aflatoxin.
When buying food, if you find that the package is not clean and has been damaged, do not buy it; buy nuts should try to choose a small package. After you buy it home, it is best to store it in a cool, ventilated, and dry place (the temperature is preferably below 20°C and the relative humidity is below 80%, and avoid direct sunlight.
