振动条件下堆码位置对猕猴桃贮藏品质的影响

Effects of stacking on storage quality of kiwifruit under oscillation

根据贮运过程中的实际情况,实验研究了堆码高度对猕猴桃贮藏品质的影响。分别研究了经历了10 Hz频率振动,不同堆码位置的猕猴桃果实放入0、5、10℃三种不同温度的冷库贮藏,其硬度、可溶性固形物含量、可滴定酸含量、维生素C含量和丙二醛含量变化。结果表明,不同堆码位置的猕猴桃果实硬度、果实可滴定酸以及维生素C含量均呈下降趋势,可溶性固形物和MDA含量均不断上升。研究发现处于中层的猕猴桃果实贮藏效果最好。因此,振动条件下堆码位置会明显影响猕猴桃贮藏品质,实际贮运过程中应加强对上层和底层果实的缓冲包装。

Based on the actual condition in the transportation process, the effects of stacking height on the storage quality of kiwifruit during the transportation process had been researched.The change processes of the firmness of the shell, the content of soluble solids,titratable acid, Vc, MDA under three different temperature of cold storage of 0,5,10℃ and 10 Hz vibration had been researched.The results indicated that the firmness of the shell,the content of titratable acid, Vc, MDA decreased and the content of soluble solids, MDA increased during the experiment. It was also found that the storage quality of the middle laid kiwifruit was best.So the effect of stacking on storage quality of kiwifruit was obviously under oscillation, and the cushioning packaging of the upper and bottom fruits should be strengthened during the actual transportation process.
