In order to extend the shelf life of cooling of pork,and provide the basis for its gas packaging components,this experiment using response surface software build different gas proportion,through the proportion of different gases and gas packaging to place it at 7 ℃ under the condition of storage,modified atmosphere research pseudomonas,lactic acid bacteria in cooling pork growth probability,total number of bacteria and other microorganisms.Studies have shown that oxygen of pseudomonas bacteria is very significant,carbon dioxide is significant for the role of lactic acid bacteria.Through the Design Expert software regression analysis of experimental data,forecast the best proportion.Pseudomonas optimized gas proportion isCO2 31％+O2 49％+N2 20％,optimized gas ratio of lactic acid bacteria:CO2 37％+O2 35％+N2 28％,optimized gas ratio of total bacteria isCO2 36％+O2 44％+N220％.
