Effects of Different Packaging on the Purine Content and Key Enzymes of Refrigerated Yellow Croaker (Larimichthys crocea)

In this study, we investigated the effects of air packaging, vacuum packaging and modified atmosphere packaging (CO2/N2: 80/20) on the purine metabolism and enzyme activities of refrigerated large yellow croakers. The results showed that modified atmosphere packaging significantly inhibited microbial growth, delayed adenosine triphosphate degradation and maintained higher IMP content (1.93 μmol/g on day 21) compared to the air packaging group (2.82 μmol/g on day 12). The total purine content...
