气调包装对H3蓝莓采后贮藏品质的影响

Effect of modified atmosphere packaging on 'H3' blueberry postharvest quality during storage

研究不同气体浓度组合的气调包装对H3蓝莓贮藏期内果实可溶性固形物含量、可滴定酸含量、固酸比、硬度、失水率、烂果率、果霜覆盖率和乙烯生成速率等指标的影响。结果表明,在蓝莓贮藏期间充入7%O_(2)+20%CO_(2)+73%N_(2),可明显提高果实固酸比,可以更好地控制果实硬度,减少果实水分的流失,降低烂果率,抑制乙烯生成速率,从而使果实保持较好的外观形态和口感。可见,气调包装可以有效地改善蓝莓贮藏期间的果实品质,延长贮藏时间。

The effects of different gas concentration combinations of modified atmosphere packaging on soluble solids content,titratable acid content,solid-acid ratio,hardness,water loss rate,fruit rot rate,frost cover rate and ethylene production rate of ‘H3' blueberry fruit during storage were studied.The results showed that filling 7%O_(2)+20%CO_(2)+73%N_(2) during the storage of blueberry could significantly increase the solid-acid ratio of the fruit,better control the fruit hardness,reduce the loss of fruit moisture,reduce the fruit rot rate,and inhibit the ethylene production rate,so that the fruit maintained a good appearance and taste.It can be seen that modified atmosphere packaging can effectively improve the fruit quality of blueberry during storage and prolong the storage time.
