摘  要:
为了探讨高压CO2加工技术对橙汁货架期的影响,将新鲜的橙汁在温度为37℃,压力60 MPa的高压CO2中处理9 min后,分别在4、 15、25和37℃下贮藏,测定果胶甲基酯酶残存相对活性、浑浊度、维生素C残留量和颜色变化。结果表明:在4和15℃下贮藏,橙汁的货架期分别在84和56 d以上;浑浊稳定性比较好;维生素C含量保持在80%以上;在4、15和25℃下贮藏颜色基本上没变化。因此,高压CO2处理橙汁可有效延长产品的货架期,此技术值得在果汁企业中广泛推广。

摘  要:
In order to study the effect of high pressure carbon dioxide treatment on the shelf life of orange juice,the prepared orange juice was subjected to high pressure carbon dioxide treatment(60 MPa for 9 min at 37℃).After storage for some time at 4,15,25 and 37℃, respectively,Pectin Methyl-Esterase(PME)activity,opacity stability,vitamin C content and color change were detected.The results show that the shelf life of orange juice stored under 4℃and 15℃more than 84 days and 56 days respectively,and more than 80%ascorbic acid was retained.Opacity stability was good.Color values were constant during storage at 4,15 and 25℃.So,the shelf life of orange juice treated by high pressure carbon dioxide was prolonged effectively,the technology of high pressure carbon dioxide treatment is worth of popularization in fruit juices industries.
