Aspergillus flavus can generally be killed by high temperature, alkaline conditions, ultraviolet light and other methods. 1. High temperature: the toxicity of Aspergillus flavus can be destroyed at very high temperature, general pasteurization or ordinary cooking heat is not enough to inactivate it completely, so killing Aspergillus flavus needs to be carried out in special high temperature machines. 2. Alkaline conditions to remove: aflatoxin can be converted into a water-soluble substance under alkaline conditions, so aflatoxin can be removed by washing with alkaline water. 3. Ultraviolet lamp The working principle of ultraviolet lamp is to use the high energy of ultraviolet spectrum to destroy the structure of microorganisms, with strong bactericidal effect, so as to achieve the purpose of disinfection, irradiation with ultraviolet lamps can effectively remove the aflatoxin on the surface of the articles. Aflatoxin is very easy to breed in grain, oil crops and dried fruits food, its harm to the human body, and the general heating method is difficult to remove the kill, so daily should try to avoid eating moldy food, do not recommend blindly kill aflatoxin.
