Progress on modified atmosphere technique for aquatic products

The research status of modified atmosphere packaging (MAP) of aquatic products technology, and the composition and effect of MAP were mainly introduced in this article. The CO2 acts on bacteriostasis, the N2 acts on filling gas, the O2 and CO act to protect color. Furthermore, from the aspect of processing of material fish, packaging materials and storage temperature, the factors on preservation of MAP were also investigated. Low temperature combined with MAP has a great inhibition effect on spoilage organisms and pathogenic bacteria, but the high concentrations of CO2 gas packaging increase the juice loss of aquatic products. MAP is more effective to extend the shelf life of aquatic products than the vacuum packaging.
