塑料薄膜小包装贮藏江安李可行性研究

Studies on Feasibility of Jiang'an Plum Preservation in Small Plastic Film Pouches

江安李采后用塑料薄膜袋小包装于3±1℃条件下贮藏，结果表明：塑料薄膜小包装贮藏李果能在10日之内快速降氧，达到MA贮藏的目的。该方法能有效防止李果水分蒸发，防止萎蔫；对抑制果实呼吸、多聚半乳糖醛酸酶（PG）活性、果胶甲酯酶（PE）活性、果实外渗液电导率的上升及过氧化氢酶（CAT）活性的下降都有明显作用，对贮藏有利。

Jiang'an plums were stored in small plastic film pouches at 3±1℃.Oxygen content in the pouches can drop rapidly for ten days, so plums can achieve self-controlled atmosphere storage.The storage method can not only avoid water-evaporating and wilting of plums ,but also inhibit the respiration of plums and the activities of polygalacturonase(PG) and pectinmethylesterase(PE).Besides, the storage method has a marked function on inhibiting the rise of conductance rate of fruit extract and the decline of catalase(CAT) activities. All of these are benefit for the storage of plums.
