A system for preserving red meat by plasma active water (PAW) vacuum packaging includes a solution mixing tank, a plasma treatment chamber, an atomization spray module, a conveyor belt, a water circulation module, and a vacuum packaging module. The solution mixing tank, the plasma treatment chamber, the atomization spray module, and the water circulation module are sequentially connected through pipes. The atomization spray module is configured to spray PAW onto the red meat on the conveyor belt, and then the vacuum packaging module is configured to vacuum-package the red meat. Utilizing PAW improves the antibacterial ability of vacuum packaging while enhancing the color stability of red meat, greatly extending the shelf life of red meat, thereby preserving red meat in a green and economical way.
