Effect of High O_2 and CO_2 Atmospheric Packaging on the Quality of Fresh-cut Pitayas
In the paper, the effects of high O2and CO2modified atmosphere combined with cast polypropylene film( CPP) packaging on the sensory and nutritional quality of fresh-cut pitayas during storage of 5 ℃ was investigated(air packaging as control). The results showed that the visual quality(firmness) and nutritional quality(vitamin C, soluble sugar) of fresh-cut pitayas packaged by high O2and CO2modified atmosphere packaging were better than the control and the degradation of betacyanins was inhibited. But there was no significant influence on the soluble protein. In general, the quality of freshly-cut pitayas was effectively maintained by high O2and CO2modified atmosphere combined with cast polypropylene film packaging. The results can provide a reference for commercial production of fresh-cut pitayas
