Aflatoxin can cause liver cancer, esophageal cancer and other diseases, at present mainly through high temperature disinfection, ultraviolet lamp, alkaline conditions to kill and other methods to eliminate. 1. High-temperature disinfection: aflatoxin belongs to high-temperature-resistant enzymes, which can withstand high temperatures of 100 degrees, generally when the temperature is greater than 260 degrees, it can be killed, at this time the main food contaminated by aflatoxin, placed in a high-temperature sterilization box for elimination. 2. Ultraviolet light: aflatoxin is not resistant to ultraviolet light, but to a high concentration of ultraviolet light, for the normal sunlight ultraviolet light can not make it kill, need to be in the ultraviolet light irradiation to kill it. 3. Alkaline condition kill: Put the contaminated articles in alkaline solution, soak and kill the aflatoxin.
