摘要: 以中华寿桃为试材,研究热空气、乙醇熏蒸结合处理对桃果实低温贮期及常温货架期间品质的影响。结果表明,48℃、4h热空气结合300μL/L乙醇熏蒸处理比单一热空气、乙醇处理更好地抑制了中华寿桃低温贮藏过程中的果肉绵化和可滴定酸、出汁率、VC含量的降低,同时显著缓解了电导率的上升,有利于保持细胞膜的完整性和桃果肉软化能力。结合处理较热空气、乙醇熏蒸单一处理更好地保持了中华寿桃采后低温贮藏和货架期的品质。

Abstract: In this study, the effects of hot air and ethanol fumigation treatment applied separately or in combination on quality changes of Zhonghuashoutao, peach during cold storage and shelf life were investigated. The results showed that 4 hours of hot air in 48 ℃ combined with 300μL/L ethanol fumigation treatment exhibited better effects than the hot air treatment or ethanol treatment. It inhibited the flesh woolliness, and also slow down the decreasing of titratable acid, juice extraction rate and vitamin C content. This treatment also alleviated the increasing of electrical conductivity during storage, the cell membrane integrity and the softening ability. The combination treatment exhibited positive effect on storage quality and shelf life of the peach during cold storage.

Key words: Zhonghuashoutao, peach, storage quality, hot air, ethanol, combination treatment
