Ouyien Environmental Packaging Products Co., Ltd. specializes in packaging professional cooked food aluminum foil bags. For cooked food packaging, in addition to the packaging method, packaging sterilization is also particularly important. After vacuum packaging of cooked food, how to perform microwave sterilization at a lower cost? According to the characteristics of microwave sterilization:
Microwave sterilization is achieved through special thermal and non-thermal effects. Compared with traditional heat sterilization, microwave sterilization can obtain the required disinfection and sterilization effect at a lower temperature and shorter time. Practice has proved that the general sterilization temperature can reach the sterilization effect of 75×80℃. In addition, microwave-treated foods can retain more nutrients and flavors, flavors, shapes and other flavors, and have a swelling effect. After routine heat treatment, the residual rate of vitamin C in vegetables is 46≤50%, microwave treatment is 60≤90%, pig liver conventional heating method is 58%, and microwave heating method is 84%.
Energy saving: Traditional thermal sterilization usually causes heat loss in the environment and equipment, and microwave directly acts on food, so there will be no additional heat loss. In contrast, you can generally save 30% or 50% of electricity.
Uniform and thorough: The traditional thermal sterilization starts from the surface of the material and then transfers to the interior through heat conduction, so it is easy to have internal and external temperature differences. In order to maintain the flavor of the food, the processing time is generally shortened, which results in the internal temperature of the food not reaching a sufficient temperature and affecting the sterilization effect. Because microwave has a penetrating effect, when food is handled as a whole, both the surface and the interior are affected, so disinfection and sterilization are uniform and thorough.
Easy to control: microwave food sterilization treatment, equipment can be switched, no conventional thermal sterilization thermal inertia, flexible and convenient operation, microwave power is continuously adjustable from zero to rated power, transmission speed is adjusted from zero to continuous, easy to control.
The equipment is simple and the technology is advanced: compared with conventional disinfection and sterilization equipment, as long as it has basic conditions such as water and electricity, it does not require boilers, complicated piping systems, coal yards and transportation vehicles.
