三疣梭子蟹属宁波名特优水产养殖品种,但三疣梭子蟹在保藏加工中容易发生褐变,哪种包装方式可抑制梭子蟹褐变并有效延长产品保鲜期,是一个值得探讨的问题.该文对三疣梭子蟹真空包装、气调包装和涂膜包装的保鲜效果进行比较.结果表明:气调包装气体配比为CO_2 50%,N_2 50%的保鲜效果较好;但真空包装与气调包装和涂膜包装的保鲜效果相比,0～4℃下,真空包装可有效抑制梭子蟹腮部和足部褐变并延长三疣梭子蟹保鲜期,保鲜效果好于气调包装和涂膜包装.

Portunus trituberculatus is a famous aquatic variety in Ningbo city and melanin is often found in storage period. It is a big problem to prohibit melanin phenomenon and prolong storage period of Portunus trituberculatus. The study was made by three package methods: vacuum package, coating package and modified atmosphere package(MAP) .The fresh-keeping effects of Portunus Trituberculatus were investigated. The results showed the efects were better when air components and ratios of MAP were CO_2 50% N_2 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℃.
