Microwave is kind of high frequency electromagnetic wave. Under the effect of electromagnetic field, the orientation of polar molecules in the materials changes with hypervelocity, causing the violent movement and mutual friction of molecules. Heat is produced and makes the temperature of food rises rapidly, the moisture is evaporated, achieving the aim of drying.
Microwave sterilization is achieved by thermal effect and non-thermal effect, having the features of low temperature and short time. While convention method requires sterilization temperature of 120℃-130℃ and the time is around one hour, microwave sterilization just requires 70℃-90℃ and the time is about 3 minutes.
