No, moldy steamed bread shows that toxic and harmful aflatoxin has been produced in it, although aflatoxin is also water-soluble. Therefore, after rinsing and boiling, some toxins can be dissolved in water, which can reduce the risk of aflatoxin intake to some extent. However, the molecular structure of aflatoxin is stable, resistant to high temperature (melting point 237℃ ~ 299℃) and not easy to be destroyed at ordinary cooking and processing temperatures. There is no guarantee that all aflatoxins in it will be killed.

Aflatoxin is the most toxic mycotoxin found so far, with acute and chronic toxicity, which can cause cancer, teratogenesis and mutation. The main target of aflatoxin harm is liver, which belongs to hepatotoxin and has destructive effect on liver tissue. Different kinds or structures of aflatoxins have different toxicity. The order of aflatoxin toxicity is AFB1> AFM1> AFG1> AFB 2 > AFM 2 > AFG 2. The experimental results show that aflatoxin B 1 is the most toxic, which is 0/0 times that of potassium cyanide, 68 times that of arsenic and 0/0000 times that of bhc. 1993, the World Health Organization (WHO) and the International Agency for Research on Cancer (IARC) listed aflatoxin B 1 as a primary carcinogen.

So please throw away the mildew in time.
