What You Need to Know
The Micvac system is a pasteurization method for the food processing industry producing ready meals. Food ingredients are inserted into a package, which is sealed. A small hole is pierced in the sealing film. The package is cooked and pasteurized in the microwave tunnel. During this process, the package works like a small pressure cooker, allowing oxygen and some steam to escape through the small hole in the film. Once steam and oxygen have left the package during cooking, the valve is applied, creating a natural vacuum. The process time is short since the food is pasteurized with microwaves. When the microwave heating process stops the valve closes. Remaining steam condenses and causes an underpressure in the package. The final result is a cooked, pasteurized and vacuum-packed product. The short cooking time in combination with the absence of oxygen in the pack is unique for the method and has many advantages. The method has been used in the food industry since 2005.
