| 摘 要： | 目的]探讨仲丁醇(2-butanol)对龙眼采后品质、抑制褐变和衰老的影响,为维持龙眼采后品质和延长贮藏期提供理论依据.方法]以石硖龙眼果实为试验材料,研究0.05%仲丁醇处理对龙眼低温(4℃)贮藏过程中果实失重率、果皮失水率、褐变指数、果肉自溶指数、可溶性固形物含量、可定量酸含量、呼吸强度和乙烯释放量等指标变化的影响.结果]仲丁醇处理能抑制龙眼果实失重和果皮水分损失;从贮藏的第5d开始,仲丁醇处理可延迟果皮褐变和果实自溶;在第15 d后,仲丁醇处理显著抑制可溶性固形物的分解和可滴定酸的产生(P<0.05);此外,仲丁醇处理能延缓龙眼果实呼吸作用和乙烯释放.结论]适当浓度的仲丁醇有助于维护龙眼采后果实品质,延缓果实衰老褐变.

| Abstract: | Objective]Effects of 2-butanol on postharvest quality of longan fruits,browning and senescence inhibi-tion were studied to provide reference for maintaining postharvest fruit quality and prolong preservation life.Method]Longan fruits(cv."Shixia")were used as materials.Effects of 0.05% 2-butanol treatment on fruit weight loss rate,peri-carp moisture loss rate,browning index,pulp breakdown index,total soluble solids content,titratable acid content,respi-ration intensity and ethylene production of longan fruits were analyzed during storage at 4℃.Result]The results showed that 0.05% 2-butanol inhibited fresh weight loss and pericarp moisture loss,and from day 5 of storage,2-butanol delayed pericarp browning and pulp breakdown.From day 15,2-butanol significantly(P<0.05)inhibited the decomposition of to-tal soluble solid and the production of titratable acid.In addition,2-butanol delayed the respiration and ethylene produc-tion of longan fruits.Conclusion]2-butanol with proper concentration can be helpful to quality maintenance of posthar-vest longan fruits,and postpone fruit senescence and browning. |
