摘要
以江安大白李为实验材料,研究二氧化氯和壳聚糖单独处理以及不同先后处理顺序的联合作用对李果采后生理和品质的影响。结果表明:与对照相比,经壳聚糖或二氧化氯单独处理的江安大白李均能有效抑制果实的呼吸强度,降低果实的失重率,维持果实的好果率,维生素C及可溶性固形物含量。壳聚糖和二氧化氯联合处理作用能更有效降低江安大白李的失重率,提高好果率。二氧化氯浸泡之后再进行壳聚糖联合保鲜处理能较好的保持江安大白李的贮藏品质,延长其贮藏寿命。研究结果可为江安大白李合理贮藏保鲜提供理论依据。
Using Jiang＇ An Dabai plum as experimental material, the physiology and quality changes of plum were treated with chitonsan and C102individually treatment and together in sequence.The results showed that the chitonsan or C102 individually treatment were able to decrease the respiration rate and weight loss of the plum, the reductions in good fruit rate, contents of vitamin C and soluble solid were effectively retarded.The combination of chitosan and C102 could reduce the weight loss and increase the good fruit rate more availably. With treating Jiang＇ An Dabai plum in sequence, chitosan coating after C102 treatment proved to be more effective in decreasing decay rates,and effectively extend the shelf-life of plum.The results could provide evidence of reasonable preservation of Jiang＇ An Dabai plum.
