There is a toxin,
It is classified as a Class 1 carcinogen by the World Health Organization,
Is the most stable fungal toxin found so far,
It is 68 times more toxic than arsenic,
10 times that of potassium cyanide,
Extremely damaging to liver tissue.
Once formed, it is difficult to remove.
It's what we often hear about as aflatoxin.
Aflatoxin 1 mg is carcinogenic. For example, China stipulates that the content of aflatoxin b1 in grain should be less than 10 μg/kg, the content of aflatoxin m1 in milk and dairy products should be less than 0.5 μg/l, aflatoxin m1 should not be detected in infant milk powder m1, and aflatoxin b1 should not be detected in dairy products.
The bitter melon seeds and bitter peanuts we sometimes eat are likely to contain aflatoxin. However, such a dose of very small intake do not worry, aflatoxin if not continuous intake, generally not in the body accumulation. About 1 week after a single intake, most of it is excreted by breathing, urine, feces, etc.
Foods with high starch content are most likely to contain aflatoxins, such as corn, peanuts, etc., once the mold aflatoxin content is very high, especially peanuts are most likely to breed aflatoxin, if a pack of peanuts has a peanut mold, it is best to throw away the whole package of peanuts, because aspergillus aflatoxin is transmitted in the form of spores, food is very easy to implicate mildew.
There are also rice, millet, wheat, beans, and potatoes that also contain aflatoxin, so if the rice has a peculiar smell, it is best not to eat it again.
In addition to peanuts, aflatoxin is also found in nuts such as melon seeds, almonds, and pistachios, which produce aflatoxin during mildew.
If you eat nuts such as melon seeds and almonds that become bitter, you must spit them out and rinse your mouth in time, if you eat them regularly, it will increase the risk of liver cancer.
Everyone must also carefully check whether it is moldy before eating nuts.
The production process of small workshops is mostly relatively simple, can not refine the raw materials, can not remove harmful substances, if the raw materials are moldy, the squeezed oil may bring aflatoxin, so buy oil should look for a reputable big brand. In addition, long-standing vegetable oils may also produce small amounts of aflatoxin.
Many families also have this habit, chopsticks are not willing to throw away until they are blackened with fine seams, and the dishwashing cloth is completely shapeless, and they are still trying to serve.
Early liver cancer in young people may be related to the chopsticks we use. Chopsticks themselves will not grow aspergillus aflatoxin, but when we usually use chopsticks to eat peanuts, corn and other foods with high starch content, the chopsticks are most likely to hide starch in the seam, and when they come and go, aflatoxin is hidden inside.
Naked chopsticks and lacquered chopsticks are easy to crack and hide food residues, resulting in aflatoxin.
It is recommended that chopsticks be changed once every six months, washed carefully in time, dried in time after washing, or try to use iron chopsticks.
You love to eat tahini, peanut butter, some merchants in order to reduce costs, with bran sesame seeds, deflated peanuts and even spoiled sesame seeds, peanuts as raw materials, of which spoiled peanuts contain aflatoxin. And this processed product is much more difficult to identify than moldy peanuts.
Many people should have heard this once very hot news, a consumer in Ruian, Zhejiang Province, because of the consumption of black fungus for 3 days, resulting in food poisoning, multiple organ failure, once dying.
The diagnosis given by the attending doctor is that it is likely to be a follow-up serious consequence caused by microbial toxins. However, what kind of bacteria or toxins are produced by the fungus during the foaming process requires further detection and judgment. What microbial toxins are possible? For example, aflatoxin, penicillin and so on.
Ordinary people should not soak for so long, Xiaobian single out this is also to remind everyone, even if it is not a grain bean, did not see mold, can not let down their vigilance to think that it is safe ah ~
Many people have said that I can not "disinfect" the food when I cook it well in the pot?
But that's not the case. The general cooking processing temperature cannot destroy aflatoxin, because the aflatoxin lysis temperature is 280 ° C. Only when it reaches 280 ° C, it can be inactivated, and the general cooking method cannot be sterilized.
Not even disinfecting cupboards, aflatoxin is resistant to ultraviolet rays.
Due to the uneven distribution of aflatoxin contamination in the entire batch of grain, it is necessary to pick up the moldy and hairy peanuts and beans in time before cooking. Food that has been moldy should not be eaten, and it should not be fed to animals. If the food the animal eats is contaminated with aflatoxin, the toxin may also enter milk, eggs and meat.
Aflatoxin in edible oil, by heating and salt frying or boiling, the detoxification effect is better, and the neutralization degradation of aflatoxin by table salt can eliminate about 95% of aflatoxin.
Aflatoxin in rice is mainly distributed on the surface of rice grains, and most of the aflatoxin can be removed by hand scrubbing three or four times when scooping rice and peanuts.
Studies have shown that leaf green can effectively inhibit the absorption of aflatoxin b1, so eating more fresh vegetables rich in chlorophyll may reduce the risk of aflatoxin poisoning.
Buy regular brands and shelf life of goods, keep food dry, sun-dried, air-dried, baked dry, dry can reduce the moisture in the food, and then seal the food or placed in a ventilated and dry place, like some rice noodles and the like do not put it in a damp place is easy to appear moldy. Molds multiply slowly at low temperatures, so you can put food in the refrigerator, but be careful not to leave it too long.
