| 中文摘要: |
| 选择了LDPE，BOPP/PE，BOPP/PET／PE，PT／AL/PE和BOPP/AI√PE等5种典型具有代表性的包装材料进行了茶叶贮藏试验，从儿荼素的角度比较了它们的处理效果。结果表明：不同阻隔性（阻气、阻湿、阻光）的包装材料对茶叶的儿茶素含量的影响存在极显著差异(P<0.01)，从儿茶素角度来讲，包装材料的处理效果优劣依次为BOPP/AI√PE，BOPP/PET／PE，PT／AI√PE，BOPP/PE和LDPE；同时，茶叶需贮藏在常温或低温、干燥、避光、与氧隔绝的环境下，儿茶素才会相对比较稳定。 |
| 英文摘要: |
| Tea storage tests were carried out by using five typical packaging materials, which were LDPE, BOPP/PE, BOPP/PET/PE, PT/AL/PE, and BOPP/AL/PE. The treatment effect was compared from the aspect of catechin content. The result showed that the effect of packaging materials of different barrier property is significant on catechin content; the treatment effect order from excellent to poor is BOPP/AL／PE>BOPP/PET/PE>PT/AL/PE>BOPP/PE>LDPE; at the same time, tea need to be stored at normal atmospheric temperature or low temperature, dry, dark, isolated with oxygen to keep catechin relatively stable. |
