Sta-Fresh果蜡处理对新疆小白杏采后品质的影响

Effect of Sta-Fresh fruit wax on postharvest quality of Xinjiang 'Xiaobai' apricots

以新疆小白杏为试材,初步探索了20℃贮藏条件下,果蜡Sta-Fresh2952与7055处理对新疆小白杏采后贮藏效果及采后品质参数的影响。结果表明:两种果蜡处理可推迟小白杏采后乙烯高峰的出现,抑制贮藏期间小白杏的呼吸速率及丙二醛(MDA)含量的积累;减少水分散失,降低腐烂率;保持较高的硬度和VC含量;延缓了小白杏的衰老进程,延长了货架期。研究结果表明,果蜡Sta-Fresh2952与7055在小白杏采后储藏和保鲜方面具有广阔的应用前景。

The effect of Sta-Fresh 2952 and 7055 on postharvest quality of ＇Xiaobai＇ apricot fruits was investigated.The changes of quality parameters such as ethylene,respiration rate,weight loss,VC and malony dialdehyde（MDA）contents were determined.Results showed that ＇Xiaobai＇ apricots treated with fruit wax significantly inhibited ethylene production and respiration rate,reduced water loss and decay rate,maintained relatively high hardness and VC content and delayed the accumulation of MDA.The results indicated that fruit wax had great potential for preservation of ＇Xiaobai＇apricots.
