不同减振衬垫对模拟运输猕猴桃生理和品质影响
|
摘要
合理包装对于减轻果实采后损伤和保持其新鲜品质具有重要作用。本研究采用模拟公路运输振动方法,研究聚苯乙烯泡沫衬垫、聚氯乙烯塑料衬垫以及自主研制的珍珠棉衬垫对猕猴桃果实生理和品质的作用效果。结果表明,三种减振衬垫均能不同程度降低猕猴桃模拟运输后的果实失重率、呼吸强度、乙烯释放量,延缓果肉软化。其中,珍珠棉衬垫能保持猕猴桃较高的硬度和可溶性固形物含量,降低失重率、呼吸强度以及乙烯释放量。综合各指标,珍珠棉衬垫效果最优,可以有效延缓猕猴桃模拟运输后的品质劣变,更利于运输后的贮藏和品质保持。
Proper package is important to prevent vibration damage and maintain quality of postharvest fruits. This study was designed to investigate the anti-vibration effects of foam,polyvinyl chloride( PVC) and self-developed expandable polyethylene( EPE) pads by simulated road transportation.The results showed that all three pads revealed great anti-vibration functions by reducing weight loss,respiration rate,ethylene production and softening.The results indicated that the EPE pad could maintain the high firmness and soluble solid contents( TSS) of kiwifruit,reduce the weight loss,respiration rate and ethylene production.In conclusion,the EPE pad exhibited the best capacity for fresh-keeping of kiwifruit,it could effectively delay the quality deterioration of kiwifruit after simulated transportaion,which was more beneficial to the maintenance of fruit quality during storage after transportation.
