Consumers now pay great attention to the pure taste of perishable foods and the shelf life of foods and attractive appearance packaging for foods, especially meat. The food industry needs to develop new food packaging technologies to meet the needs of its customers. Due to the development of society and the increasing demand for high quality by customers, the use of vacuum packaging machines to keep fresh and perishable foods has gradually become a market trend.
 
  
The basic principle of fresh meat vacuum packaging machine packaging is to isolate the cooling meat from the outside air. The mixture of oxygen and carbon dioxide is used to make the meat color bright and beautiful while inhibiting the growth of bacteria. When a certain amount of oxygen is kept in the package, myoglobin is converted to oxygenated myoglobin, and the muscles are bright red with fresh meat. The role of oxygen is to make the color of the meat a bright red color that consumers like. The color of the meat is important to the psychological impact of the consumer. The closed container is filled with 80% oxygen, so that the meat maintains a bright color without too much oxygen and discoloration. The role of 20% carbon dioxide is to inhibit a small amount of residual bacteria during slaughter and prolong the shelf life.
