Research advance in modified atmosphere packaging of aquatic products

Modified atmosphere packaging( MAP) can extend shelf-lives of most fishery products by inhibiting spoilage bacterial growth. In MAP gas system,CO2 plays more important role than O2 or other gas. The qualities and shelf-lives of MAP products are influenced by many factors,such as gas mixture,storage temperature,species, original qualities,packaging materials,and the ratio of gas volume to material weight,among which storage temperature is the most important factor. Many studies found the spoilage of MAP fishery products was induced by Specific spoilage organisms( SSOs). CO2-resistant Photobacterium phosphoreum was found in MAP cod at 0℃, whereas,Psychrophilic Lactic acid bacteria was considered as SSOs of different MAP fishes. Moreover,aquatic products treated with MAP could get a longer shelf-life and more safe quality than those treated with air or vacuumpackage under the same processing conditions.
