Aflatoxin is odorless, tasteless and colorless, and it can also withstand the general temperature (cracking temperature is as high as 280℃), so ordinary cooking and processing methods can not completely destroy its toxicity.
According to Chinese regulations, the maximum content of aflatoxin in peanut and edible oil is less than 20 μ g/kg. . If the content of aflatoxin in the body is above the level of 1 mg/kg, cancer can be induced. If it is a person of 70 kg, a single intake of 20 mg of aflatoxin will kill him.
Foods susceptible to aflatoxin:
Nuts: peanuts, walnuts, melon seeds, pistachios, hazelnuts and pine nuts.
Cereals: corn, rice, barley, wheat and beans.
Grain and oil products: peanut oil and corn oil.
Home-made fermented food: fermented bean curd
