活性气调包装对番木瓜品质的影响

Effects of intelligent modified atmosphere packaging on the quality of Carica papaya

研究了内含CO2吸附剂的活性气调包装对番木瓜综合品质的影响。与未加吸附剂的普通气调相比,活性气调包装能够降低番木瓜的氧气消耗率,推迟番木瓜果肉内多糖和还原糖的达峰时间,减少番木瓜的失水率,提高气调包装对番木瓜的保鲜效果,但对维生素C影响不显著。研究结果表明活性气调包装在番木瓜保鲜贮藏中具有一定的推广应用价值。

The effects of active modified atmosphere packaging（MAP）with in-pack CO2 adsorbent upon papaya’s attributes were examined. Compared to routine MAP,the active MAP was able to depress the rate of oxygen consumption by papaya,delay the summit occurrence of sugar contents in pulp,reduce the weight loss of the fruit,and enhance the efficiency of MAP in the quality keeping of papaya. However,contents of vitamin C in papaya packaged by active MAP were observed changing in a similar way to that in MAP without CO2 adsorbent. These results indicated that the active MAP was of certain practical values in the postharvest storage of papaya fruit.
