Inhibition of melanosis and microbial growth in Pacific white shrimp (Litopenaeus vannamei) using high CO2 modified atmosphere packaging

Preserving quality of crustaceans requires efficient modified atmosphere packaging (MAP). Effects of CO2 (20%–80%) on quality and melanosis in chilled Pacific white shrimp (Litopenaeus vannamei) under O2 concentrations of 5 and 15% were investigated. Increased headspace CO2 and lipid oxidation contributed to loss of firmness due to protein degradation. Image analysis indicated increased degree of melanosis at higher O2 concentration. High CO2...
