Food disinfection is an important part of ensuring food safety and preventing the spread of foodborne diseases. Traditional food disinfection methods have undergone a long period of development, including physical methods, chemical methods, and biological methods. These methods have their own advantages and disadvantages, but they all play an important role in different situations. Traditional food disinfection methods are widely used in food processing, catering services, medical and health care, water treatment, and agriculture. Different methods choose appropriate disinfection methods according to the type of food, processing environment, and needs to ensure food safety and quality.

[0003] Conventional food disinfection methods include: 1. Physical method: High temperature treatment is an effective sterilization method. Common high temperature treatments include boiling, steaming and high temperature sterilization. The cell structure of microorganisms is destroyed by high temperature to achieve the purpose of sterilization. 2. Chemical method: ① Chemical disinfectants: such as chlorine, hydrogen peroxide, alcohol, vinegar, etc., can destroy the cell membrane and protein of microorganisms to achieve the effect of sterilization. Commonly used for surface disinfection and water treatment. ② Antibiotics and preservatives: Antibiotics and preservatives are added during food processing and storage to inhibit the growth and reproduction of microorganisms and extend the shelf life of food. 3. Biological methods add beneficial microorganisms such as lactic acid bacteria to ferment food to produce lactic acid, reduce the pH value of food, and inhibit the growth of harmful microorganisms. Enzyme treatment: Use the biological activity of enzymes to destroy the cell wall or membrane of microorganisms to achieve the effect of sterilization. Common ones include rennet, papain, etc. The existing disinfection methods have the problems of incomplete disinfection, drug residues or complex processes and high costs. Therefore, it is very necessary to design a new disinfection and preservation treatment method.
