    摘要:

    根据实际运输情况,研究了运输过程中振动频率和振动加速度对猕猴桃贮藏品质的影响。通过测定猕猴桃在10,20,30,40,50 Hz 5种振动频率以及2.5,5.0,7.5 m/s2 3种振动加速度下硬度、可溶性固形物、可滴定酸、VC、丙二醛(MDA)的含量变化来评定其品质变化,以确定振动频率和振动加速度对猕猴桃贮藏品质的影响。结果表明,随着试验进行其硬度、可滴定酸、VC含量均下降,可溶性固形物、MDA含量均上升。研究发现在20 Hz的振动频率、2.5 m/s2的振动加速度下猕猴桃损伤最小。

    Abstract:

    Based on the actual situation in the transport process, the effects of mechanical vibration frequencies and acceleration on the storage quality of kiwi fruit was investigated. The change processes of storage quality of kiwi fruit were studied under five vibration frequencies of 10, 20, 30, 40, 50 Hz and three vibration accelerations of 2.5, 5.0 and 7.5 m/s2. Moreover the effects of mechanical vibration on the hardness, the content in internal soluble solids, titratable acid, VC, and MDA of each group of kiwi fruit have been analyzed. The results indicated that the hardness, titratable acid, VC were decreased whereas the content in internal soluble solids and MDA were increased during the time of experiment. It was also found that 20 Hz vibration frequencies and 2.5 m/s2 vibration accelerations was the least loss damage condition for kiwi fruit storage quality during the transportation process.
