摘要
【目的】研究不同磷脂酶D(PLD)抑制剂处理对采后龙眼果实贮藏性质的影响,为龙眼保鲜新方法的开发应用提供理论依据。【方法】以采后"石硖"龙眼果实为试验材料,分别用25 mg/kg的PLD抑制剂正丁醇、仲丁醇、溶血磷脂酰乙醇胺、2,3-二磷酸甘油酸、Wortmannin、沙丁胺醇、色甘酸钠进行处理,分析在常温(25±0.5)℃贮藏过程中龙眼果实的品质变化。【结果】仲丁醇处理后的龙眼果实褐变指数及自溶指数上升慢于对照果,可溶性固形物含量高于对照果,果实失重率低于对照果;与其他抑制剂处理果和对照果相比,较好地保持了龙眼果实采后品质。【结论】PLD抑制剂仲丁醇处理能有效减缓贮藏过程中龙眼果实的品质劣变,具有一定的保鲜效果。
[ Objective ]The effects of phospholipase D （PLD） inhibitors on storage properties of postharvest longan fruits were studied in order to provide theoretical references for developing new longan preservatives. [Method]Longan fruits （cv. ＂Shixia＂） were treated by 25 mg/kg PLD inhibitors n-butanol, sec-butanol, lysophosphatidylethanolamine, 2,3-bis-phosphoglycerate, Wortmannin, salbutamol, and sodium cromoglycate, respectively. The postharvest properties of these longan fruits were analyzed during storage at （25±0.5）℃. [Result]The results showed that the fruits treated with sec-butanol had lower pericarp browning and pulp autolysis, higher soluble solid content,and less fruit weight loss com- paring with control. Compared with other PLD inhibitor treatment and the control, sec-butanol treatment could better maintain the fruit quality of longan. [Conclusion]PLD inhibitor sec-butanol could effectively postpone quality deterioration of longan fruits during storage.
