The fresh-keeping effects of Portunus Trituberculatus were investigated. The results showed the efects were better when air components and ratios of MAP were CO2 50% N2 50%. Compared with coating package and MAP, vacuum packing could inhibit the production of melanin in Portunus Trituberculatus gills and legs and prolong storage period effectively at 0-4℃.
