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.
