Research on the Preservation Effect of Paper Plastic Compound Bags on the Lychee

The influence of a paper plastic compound bag and commercially available storage bags on the storage quality of the lychee at low temperature (5 °C) was investigated. The packed lychee qualities during storage were determined by the browning index, decay rate, soluble solids content, titrate acidity, and Vitamin C concentration. The lychee with ordinary commercial packaging bags could be kept 6 days and the shelf life of lychee with a paper plastic compound bag was 11 days. The obvious browning and water loss rate of lychee were obtained with ordinary commercial packaging bags. The paper plastic compound bag could delay effectively the appearance of the white mold.
