摘  要：
研究不同低温驯化方式结合冰温贮藏对蓝莓采后生理和贮藏品质和保鲜效果的影响。采用10℃放置12 h后转入4℃放置12 h和在4℃放置24 h这两种驯化方式处理蓝莓,然后在冰温库中贮藏70 d,每10 d测一次相关指标。结果表明,与直接冰温贮藏和冷藏相比,低温驯化处理对延缓蓝莓的腐烂、抑制VC和花色苷含量的减少、保护蓝莓果霜均有明显效果,并且抑制了蓝莓的呼吸强度和乙烯释放速率,对过氧化氢酶和脂氧合酶活力也有很明显的抑制效果。其中经10℃放置12 h后转入4℃放置12 h处理的效果最优。说明经低温驯化后冰温贮藏蓝莓的保鲜效果优于直接冰温和冷藏。

摘  要：
The effect of cold acclimation combined with ice-temperature storage(CACITS) on the quality of blueberries was investigated in this study. Blueberries were acclimated at 10 ℃ for 12 h, then at 4 ℃ for 12 h or at 4 ℃ for 24 h. Physiochemical parameters and nutritional composition were measured every 10 days during 70 days of storage. Results showed that cold acclimation combined with ice-temperature storage was more effective in delaying the decay of blueberries, inhibiting the decrease in vitamin C and anthocyanins, and protecting blueberry bloom when compared with single cold storage and controlled freezing-point storage. Moreover, the combined treatment suppressed respiratory intensity and ethylene generation rate, and lowered both CAT and LOX activities, thus extending the storage period. Among two treatments, cold acclimation at 10 ℃ for 12 h followed by 4 ℃ for 12 h was more effective, which illustrates that the efficiency of direct controlled freezing-point storage and cold storage can be enhanced by their combined use.
