超高氧高阻隔膜气调包装对鲜切胡萝卜品质的影响

Effects of Superatmospheric Oxygen Modified Atmosphere Combined with High Barrier Film Packaging on Quality of Fresh-cut Carrots

高氧气调包装是近年来研究较多的气调包装方式之一.研究了在不同储藏温度(4,15,25℃)下,高阻隔膜超高氧气调包装的鲜切胡萝卜品质变化规律(对照空气包装).结果表明,超高氧气调包装显著增加了鲜切胡萝卜的失重率、呼吸强度,同时加速了维生素C、总胡萝卜素含量的损失,但能提高多酚类物质含量.总之,高阻隔膜超氧气调包装不能有效地维持鲜切胡萝卜的品质.

High oxygen modified atmosphere packaging was one of the hottest packaging techniques on fresh-cut fruit and vegetables in recent years. The aim of this study was to investigate the effects of super- atmospheric oxygen modified atmosphere combined with high barrier film packaging on the quality of fresh-cut carrot during storage at different temperature （4℃ , 15 ℃ , and 25℃ ）. Using the packaging box filled with air as control, the results showed that the loss of weight, loss of vitamin C and total caro- tene and the respiratory intensity of fresh-cut carrot packaged by superatmospheric oxygen were signifi- cantly increased than the control. But the content of phenol compounds in fresh-cut carrot was higher than the samples packaged with air. In general, the quality of fresh-cut carrot was not effectively maintained by superatmospheric oxygen modified atmosphere combined with high barrier film packaging.
