Application of Microwave in The Sterilization of Meat

Microwave is electromagnetic wave between the 100mhz--100000mhz band. The electromagnetic field is the main factor of the bacterial death, especially at the low-temperature. 20KW microwave food sterilizer can be used to sterilize smoked fish, chicken and duck meat. And it’s sterilization effect is good. After sterilization treatment, the barbecued pork can be extended for 7 days.

Now this kind of technology has been popularized to various meat products manufacturers. One Dutch food processing company uses microwave technology to keep the fresh of meat and fish. Those food can be kept freshness in the 0~4 freezers for 6 weeks, and the price is close to frozen food.

Microwave food sterilization has some advantages. Firstly, the speed of microwave is quickly. The microwave uses its transmission function to take the heat effect and the non-thermal effect. So the bacterium would be killed rapidly. Secondly, low-temperature sterilization can maintain the flavor of meat. Microwave processing can maintain the more fragrance and other flavors. Thirdly, microwave food sterilization can save energy. The electromagnetic conversion rate of microwave is high, better than the heating. Fourth, microwave equipment easy to carry on. One whole production line only needs one operator. Finally, microwave equipment does not produce heat radiation. It can improve the working environment.
