Effect of Modified Atmosphere Packaging on Preservation of Fresh-cut Lotus Roots

Abstract

Abstract: In order to keep quality and increase shelf life of fresh-cut lotus roots,the effect of modified atmosphere packaging on quality of fresh-cut lotus roots was studied.The fresh-cut lotus roots were packaged in eight different initial O2,N2 and CO2 concentration,then stored at 4 ℃ respectively,and the content of vitamine C,PPO activity,browning degree and pH value were determined regularly. The results showed that there is close relationship between PPO activity and browning degree of fresh-cut lotus roots. The quality of appearance of the fresh-cut lotus roots treated by 100% O2 is the best,the PPO activity is inhibited,and the loss of VC is smaller and the drop of pH value is lower than that of control sample respectively.

Key words: fresh-cut lotus roots, modified atmosphere packaging, preservation
