is now the hottest and humid time of the year. In this environment, the “vitality” of aflatoxin is the most vigorous. It is almost everywhere. It may parasitize in your kitchen, drawer, toilet

and

in a word, human beings will shiver at the sight of it, after all, its toxicity is too strong! How strong is the carcinogenicity of aflatoxin? The reason why people are so afraid of aflatoxin is that it is a primary carcinogen. According to Gao Qilong, a doctor in Henan Cancer Hospital, aflatoxin was classified as a class I carcinogen by the World Health Organization as early as 1993. As for the toxicity of aflatoxin, it is 10 times as much as potassium cyanide, 68 times as arsenic, and 70 times as carcinogenic as dimethylnitrosamine.

to be frank, if you eat a large amount of aflatoxin at one time, people will have fever, vomiting, jaundice, ascites and lower extremity edema and other symptoms.

and

can cause serious problems in liver metabolic function due to its toxicity. If the dosage is too large, it will lead to liver failure, and people will go to the West directly. If it is a long-term low-dose intake, the human liver and kidney function is seriously damaged, the risk of cancer is almost 100%. In addition to liver cancer,

and

can induce gastric cancer, kidney cancer, rectal cancer, breast cancer, ovarian cancer and small intestinal cancer. Two, aflatoxin like to “hide” in these five places,

,

temperature of 26 ℃ ~ 28 ℃, the most suitable for the breeding of Aspergillus flavus. If the temperature reaches about 33 ℃ and the humidity reaches 90%, Aspergillus flavus will secrete a large amount of aflatoxin. Therefore, the humid and sultry environment in summer is a good season for Aspergillus flavus to breed. Usually, it likes to parasitize on these kinds of food. Peanut is rich in oil, and aflatoxin is easily soluble in oil. Once the environment is suitable, peanut molds and aflatoxin will be produced. In addition, walnuts, melon seeds, pistachios, hazelnuts, pine nuts and other nuts are very vulnerable to Aspergillus flavus pollution. Once this kind of food appears mildew, absolutely cannot eat. Grain grain

wheat, barley, corn, rice, sorghum, soybean and other beans are also suitable for the propagation of Aspergillus flavus.

and

for example, when the corn is not harvested, it is a humid and hot summer, and some corn is exposed outside the skin, causing its germination and mildew, which is aflatoxin. In addition, grain harvest, if not after drying on the storage, is also prone to mildew.

3. Self made fermented food

,

many families like to pickle their own sauce, such as tofu milk, soy sauce and so on. However, if it is not handled properly, Aspergillus flavus will easily grow. The aflatoxins in dairy products

will first appear in grains. If mildewed grains become feed, some of the toxins will be stored in animals, while others will be transformed into milk or urine, with a general conversion rate of 3.45% to 11.39%. Edible oil

and milk are the same factors caused by moldy grain. If moldy peanut or soybean is used to press oil, aflatoxin will appear in these oils.

some people may ask, the temperature in the process of oil extraction is very high, will Aspergillus flavus not be killed? You look down on it. The stability of aflatoxin is very good. It needs a high temperature above 260 degrees to completely decompose it. In daily life,

and

can’t produce such high temperature at all, unless it’s a steel-making plant. Seasoning

seasonings such as dried pepper, dried fennel, star anise and so on, once moldy, aflatoxin will also appear. In order to reduce the dry storage of spkds and spkds, the storage of “spkds” and “spkds” should be avoided.

and

in our daily life, when we buy grain and oil products, we must buy the products of regular manufacturers. If the packaging is damaged, we can’t ask for them. Moreover, we should avoid storing too much grain and oil at home to prevent mildew. Dairy products and other food purchase, also want to choose to the regular place as far as possible.

should be washed before cooking. Since aflatoxin is soluble in water in alkaline environment, some baking soda can be put in when washing.

and

in addition, in daily life, whether it is food or snacks purchased, once moldy phenomenon, absolutely can not be eaten again.

and

can effectively prevent the mildew of food by carefully watching and smelling, but not too much stored food, which can also put an end to the invasion of aflatoxin. Interaction between

and

: what else can aflatoxin be stored in?
