摘要
以‘粉蓝’蓝莓为试材,采用CO_(2)冲击不同时间后贮藏于气调环境内60 d,出库后进行货架试验,研究各处理对蓝莓货架期品质的影响,以期为延长蓝莓的货架期提供参考依据。结果表明:通过CO_(2)冲击后,贮藏及货架期果实品质均要好于对照组,而冲击时间不同,效果也不同;其中冲击24 h的果实表现最好,其在贮藏后的货架期腐烂率、呼吸强度、脂氧合酶(LOX)和过氧化物酶(POD)活性最低,硬度、可溶性固形物含量、花色苷含量、维生素C含量、多酚含量、超氧化物歧化酶(SOD)活性能维持最高。综上,通过采后CO_(2)冲击能有效的延长贮藏后蓝莓果实的货架期,但冲击时间不宜过长,以24 h为宜。
The‘Fenlan’blueberry was used as the test material,after different time of CO_(2)shock,the blueberries were stored in a modified atmosphere for 60 days.After delivery,the shelf test was carried out,the effect of each treatment on the shelf-life quality of blueberries was studied,in order to provide a reference for prolonging the shelf life of blueberries was studied.The results showed that after CO_(2)shock,the fruit quality was better than that of the control group during storage and shelf life,and the effect was different with different shock time;among them,the fruits impacted for 24 hours showed the best performance,and their shelf-life decay rate,respiratory intensity,lipoxygenase(LOX)and peroxidase(POD)activities were the lowest,while their hardness,soluble solids content,anthocyanin content,vitamin C content,polyphenol content and superoxide dismutase(SOD)activity were the highest.In conclusion,the shelf life of blueberry fruits could be effectively prolonged by post-harvest CO_(2)shock,but the shock time should not be too long,and the optimum time was 24 hours.
