Abstract:

Preliminary study of the fresh-keeping effect of modified atmosphere packaging on South America white prawns was conducted. Sensory evaluation and biochemical and biochemical analysis were performed on the prawns preserved in a modified atmosphere box with different proportions of mixed O2, CO2 and N2. The shelf life of fresh South America white prawns was extended by modified atmosphere packaging and better fresh-keeping effects were observed when pretreatment of the fresh prawns with 10% sorbitol followed by modified atmosphere preservation with the composition of 75% CO2 + 20% N2 + 5% O2.

Key words: modified atmosphere preservation, polyphenol oxidase, total volatile basic nitrogen (TVB-N), microbial index
