摘　　要：目的研究高阻隔HDPE包装对NFC橙汁品质和货架期的影响,为果汁生产加工企业提供信息和参考。方法采用巴氏杀菌法对NFC橙汁进行灭菌处理,研究在4,25,37℃时PET包装、普通HDPE包装、高阻隔HDPE包装的NFC橙汁各项指标的变化情况,通过对抗坏血酸和整体接受度的结果分析,建立NFC橙汁的动力学模型,利用阿伦尼乌斯方程对其货架期进行预测。结果高阻隔HDPE包装相较于其他2种包装的NFC橙汁褐变小、抗坏血酸和胡萝卜素损失少、喜好度高。以抗坏血酸含量损失50%为标准,温度为4,25,37℃时的货架期分别为152,55,31 d;以整体接受度5分为标准,温度为4,25,37℃时的货架期分别为183,44,21 d。结论高阻隔HDPE包装可以有效地延长NFC橙汁的保质期,并保证其在保质期内的品质,在NFC果汁中有很好的应用前景。The effect of high barrier high-density polyethylene(HDPE)packaging on the quality and shelf life of NFC orange juice was studied to provide information and reference for juice processing companies.Pasteurization was used to sterilize the not-from-concentrate(NFC)orange juice.The changes of various indicators of NFC orange juice were studied using samples in high barrier HDPE,regular HDPE and PET bottles stored at 4,25,37℃.The kinetic models of the quality change of NFC orange juice were established.The Arrhenius equation was utilized to predict the shelf life of NFC orange juice using the ascorbic acid content and overall acceptance as indicators.Among the three packages used,NFC orange juice packed in high barrier HDPE bottles showed less browning with less ascorbic acid and carotene content loss and higher preference.Taking the ascorbic acid content loss of 50%as the standard,the shelf life of NFC orange juice in high barrier HDPE packages at 4,25,37℃were determined to be 152,55,31 d,respectively.Taking the overall acceptability of 5 as the standard,the shelf life of NFC orange juice in high barrier HDPE packages at 4,25,37℃was 183,44,21 d,respectively.Therefore,high barrier HDPE packages could effectively extend the shelf life of the NFC orange juice and improve its quality during storage;hence,it has great potential for applications in NFC juice.
