The mechanism of microwave sterilization preservation:
Microwave sterilization, preservation is hope will food treated with microwave energy to make the loss of vitality of the bacteria, such as microbial pest or death, to ensure food shelf life must be containing bacteria amount does not exceed the health law regulations still allowed range, so as to prolong the shelf life.The following briefly describes the mechanism of microwave sterilization preservation: it is well known that bacteria, adult and any biological cells, is made up of water, protein, nucleic acid, carbohydrate, fat and mineral raw form a complex compound such as condensing medium.In which water is the main ingredient, biological cell content in 75-85%, because all sorts of bacterial physiological activities must have water to participate in to undertake, and the growth of bacteria breeding process, the absorption of various nutrients is through the cell membrane diffusion, osmosis adsorption to complete.Under the action of microwave field in a certain intensity, the insect food and bacteria can also by molecular polarization relaxation at the same time to absorb microwave energy to heat up.Because they are condensed matter medium, exacerbating the intermolecular forces can microwave energy state transformation.So that the protein has no polarity of thermal motion and rotation from two aspects, the spatial structure change, or destruction, and the protein denaturation.After the protein metamorphism, its solubility, viscosity, stability, swelling, permeability, both have obvious change, and loss of biological activity.On the other hand, the microwave non-thermal effect in the sterilization of can play the special function of conventional physical sterilization did not.Is also one reason for killing bacteria.It is by the thermal effect of microwave energy or athermal biological effect, interfere with the normal metabolism of the worm and bacteria, undermined its formation conditions and slow speed of genetic breeding insecticidal sterilization and to achieve.

1, time is short, fast
Conventional thermal sterilization is through the heat conduction, convection and radiation way would transmit the heat from food surface to inner.To achieve the sterilization temperature, often take a long time.Microwave sterilization is microwave can and food and its bacteria and other microorganisms direct interaction, the combination of thermal effect and non-thermal effect, achieve rapid warming antiseptic effect, shorten processing time, and the sterilization effect of various materials in commonly 3 to 5 minutes.
2, low temperature sterilization keep nutrition and traditional flavor
Sterilization is through special heat and non-thermal effect of microwave sterilization, compared with conventional thermal sterilization, can be in lower temperature and shorter time can get the required disinfection sterilization effect.Practice shows that in general the sterilization temperature at 75-80 °C can reach the effect, in addition, the microwave processing of food can retain more of the nutrients and flavor, such as colour, fragrance, taste and shape and expansion effect.Such as conventional thermal processing vegetables retain vitamin C is 46-50%, and microwave treatment is 60-90%, conventional heating pork liver vitamin A is 58%, and the microwave heating is 84%.
3, save energy
Conventional thermal sterilization often exists in the environment and equipment heat loss, and microwave is directly in the food processing, so no additional heat loss.In addition, the conversion efficiency of the electrical energy to microwave energy in 70-80%, compared to the party, can generally be electricity saving 30-50%.
4, even completely
Conventional thermal sterilization starts from the material surface, and then by heat conduction to internal.Temperature difference between inside and outside.In order to keep food flavor, shorten processing time, often food without enough internal temperature and the effect of sterilization effect.As the microwave penetration, food processing, the whole surface and internal all at the same time by role, so uniform and disinfection sterilization, thoroughly.
5, easy to control
Microwave food sterilization process, the equipment can out-of-the-box, no thermal inertia of conventional thermal sterilization, convenient operation and microwave power can continuous adjustable from zero to rated power, transmission speed continuous adjustment from scratch, easy to control.
6, simple equipment, advanced technology
Compared with the conventional disinfection sterilization, microwave sterilization equipment, do not need to boiler, complex pipe system, coal yard and transport vehicles, such as water, electricity as long as the basic conditions.
