Effects of modified atmosphere packaging on quality of salmon fillet in low temperature logistics

To investigate the effect of modified atmosphere packaging with different CO2concentration(50%CO2+50% N2,60% CO2+40% N2 and 70% CO2+30% N2)on quality of salmon(Salmonidae) in low temperature logistics with temperature fluctuation,sensory evaluation,p H value,a*-values,total volatile basicnitrogen(TVBN),microbiological,and K-values were assayed periodically. The results showed that the three kinds of MAP were useful to restrain the quality degradation of salmon caused by the temperature variation in low temperature logistics. However, MAP( 70 % CO2+ 30 % N2) was the best for inhibiting microbial growth and histamine generation. The results suggested that MAP could decrease the quality degradation rate of salmon in inadequate low temperature logistics effectively.
