Abstract: The objective was to investigate the effect of different package methods on quality change of nian zhuan during storage at 4℃. In this experiment nian zhuan were packaged with PE natural package,vacuum package(VP) and modified atmosphere package(MAP,70% N₂ + 30% CO₂),the sensory evaluation,moisture content,pH,color,total numbers of colony and texture property were analyzed.The results showed that the influence of different package manners on quality change of nian zhuan samples were significant differences(p<0.05),MAP was the best storage method.The sensory evaluation of PE natural package and VP samples were significantly decreased after 6 days,however the MAP samples still had a higher sensory quality after 10 days.Meanwhile, the MAP could inhibit microbial reproduction, delay the descent rate of sample pH and moisture content,the hardness and chewiness of samples were also lower than other package manners, however the differences of springiness and cohesiveness were not significant(p>0.05).Based on the above analysis,the shelf life of PE natural package, VP and MAP samples were 4 d,6 d and 10 d,respectively.Thus,the application of MAP to nian zhuan could maintain the color and flavor of samples,guarantee the quality of sample and extent the shelf life.
