Abstract:Under the condition of packaging by high oxygen modified atmosphere (100%) combined with high barrier film, the quality variation of fresh mulberry fruit was investigated. Taking air packaging as control, the CO2/O2 concentration of package, the visual and nutritional quality parameters were determined to find out the variation trends of these parameters during storage at 4 ℃. The results showed that the treatment of high oxygen modified atmosphere packaging inhibited the anaerobic respiration in mulberry fruits. The firmness, soluble protein and sugar, vitamin C and sensory quality in fresh mulberry fruits packaged by high oxygen modified atmosphere were better than the control during the last days of storage although these parameters were more inferior than control at the first four days. In addition, the treatment showed little influence on chlorophyll, color, and anthocyanin of the samples. Thus, the quality of fresh mulberry fruit was effectively maintained by high oxygen modified atmosphere packaging.
