The advantages of microwave sterilization of food mainly include:

1. Fast: Microwaves can quickly penetrate food and generate heat internally, allowing the food to reach the required sterilization temperature in a short time, thus greatly shortening the sterilization cycle and improving production efficiency.

2. High efficiency: Microwave sterilization can achieve efficient sterilization effects at lower temperatures, so it can retain the nutrients, taste and color of food, and reduce food quality losses caused by high temperatures.

3. Uniform: Microwaves can produce uniform heating within the entire food, ensuring the uniformity of sterilization and avoiding the problem of incomplete sterilization caused by uneven heat that may exist in traditional sterilization methods.

4. Environmental protection: Microwave sterilization does not require the addition of additional chemicals. The sterilization effect can be achieved simply through microwave heating. Therefore, the potential harm of chemical residues to food safety and the environment is avoided, and it meets environmental protection requirements.

5. Good sterilization effect: Microwaves can penetrate deep into the food and completely inactivate microorganisms, which can effectively extend the shelf life of food, reduce food deterioration and loss, and improve food safety and quality.

6. High degree of automation: Microwave sterilization equipment can realize automated operation and control the heating process through preset programs and parameters. It is easy to operate and improves the efficiency and consistency of production.

In summary, food microwave sterilization has the advantages of rapid, efficient, uniform, environmentally friendly, good sterilization effect and high degree of automation, and has gradually become one of the important sterilization technologies in the food processing industry.
