黄皮精油-壳聚糖复合涂膜对番木瓜果实常温贮藏品质及生理的影响

Effect of Clausena lansium oil and chitosan compound coating on physiology and quality of papaya fruits at ambient temperature

  • 摘要: 以"日升"番木瓜为实验材料,采用黄皮精油-壳聚糖复合涂膜处理果实,通过定期测定常温(25℃)贮藏期间番木瓜果实的外观和营养品质等生理指标,探究黄皮精油-壳聚糖复合涂膜对番木瓜的贮藏品质及生理的影响。结果表明,黄皮精油-壳聚糖复合涂膜处理对番木瓜采后具有明显的保鲜作用,能减少果实失重率和硬度的下降,同时能维持可溶性固形物(TSS)和维生素C(VC)含量,抑制相对电导率和丙二醛(MDA)含量的积累,能显著抑制番木瓜果实病情指数上升,延缓果实腐烂,其中以0.8%壳聚糖+40μL/L黄皮精油复合涂膜的保鲜效果最好。但壳聚糖单一处理的番木瓜果实的保鲜效果不显著,其失重率和相对电导率在贮藏后期均高于对照。因此,0.8%壳聚糖+40μL/L黄皮精油涂膜处理番木瓜能维持果实较好的品质和贮藏性能,延长果实的贮藏时间,可为开发出一种替代化学药剂的安全无毒的生物保鲜方法提供参考。 

     

    Abstract: In this research, the fresh-keeping effect of Clausena lansium oil and chitosan compound coating on the papaya fruits (Risheng variety) (Carica papaya L.) at ambient temperature (25 ℃) were investigated.The appearance feature and nutrition quality changes of fruits were monitored periodically during storage.Results showed that the Clausena lansium oil and chitosan compound coating had significant preservation effects.With the application of Clausena lansium oil and chitosan compound coating, the decrease of total soluble solids (TSS) of papaya fruits was delayed, hardness, weightlessness, vitamin C (VC) and moisture in fruit tissue maintained normal during a longer time, and the increase of malondiadehyde (MDA) content and relative conductance were significantly inhibited, of which 0.8% chitosan and 40 μL/L Clausena lansium oil compound coating was the best.But chitosan coating had no significant preservation effects, of which hardness and relative conductance were higher than the control group during the later stage of storage. Thus, 0.8% chitosan and 40 μL/L Clausena lansium oil compound coating could maintain higher storage quality and extend the storage time of papaya fruits at ambient temperature, which could be used as a safe, non-toxic, biological preservation method to alternate to chemicals.
