Excess water loss induced by simulated transport vibration in postharvest kiwifruit

Road transport vibration stress impact on ‘Palmer’ mangoes quality and shelflife

“…The authors found that fruits under stress lost 6% more weight than those in the control group, relating the acceleration of moisture content reduction to the increase in the amount of ethylene released by respiration intensification caused by grape stress during transportation. Wei et al (2019) observed that although there was no visible damage to the surface of 'Xuxiang' kiwifruit, simulated vibration (20 Hz for 5 hours) stimulated water loss, which was attributed to intracellular damage that accelerated fruit wilting. This loss may affect fruit firmness and ripening, reinforcing the importance of the type of packaging and transportation of fruits in ensuring good quality for end consumers.…”

“…Vibration generated by vehicles during road transport is one of the causes of fruit damage, which can be visually detectable or not. Qualitative and quantitative changes caused by vibration in fruits have been studied by several researchers in recent years, for fruits such as: watermelon (SHAHBAZI et al, 2010), melon (ZHOU et al, 2015), banana (WASALA et al, 2015), grape (JUNG et al, 2018), apple (SPRINGAEL et al, 2018), and kiwifruit (TABATABAEKOLOOR et al, 2013;WEI et al, 2019). Springael et al (2018) stressed that transport vibrations are a major contributor to apple perforations and, as a result, losses can be attributed to fungal diseases that enter through injured or perforated tissues and contaminate the fruit.…”

“…In this case, the authors suggest a cost-based transport route planning, avoiding road segments that are poorly maintained or more susceptible to induce higher vibration amplitudes, for thus decreasing the loss rate of apples. Jung et al (2018) and Wei et al (2019) simulated laboratory-scale vibration experiments to evaluate the effect of transport stress on fruit quality. The first authors verified that vibration stress resulted in greater weight loss and higher ethylene production, which could accelerate the degradation of packed grapes.…”

“…The first authors verified that vibration stress resulted in greater weight loss and higher ethylene production, which could accelerate the degradation of packed grapes. Similarly, Wei et al (2019) concluded that the simulated transport vibration caused intracellular damage to kiwifruit tissues, accelerating water loss and wilting.…”

Evaluation on simulative transportation and storage quality of sweet cherry by different varieties based on principal component analysis

“…In the whole cold chain process, transportation and storage, interacting parts between the fruit and the box or fruits will be subjected to various pressures, such as squeezing, friction, collision and impact (Wei et al, 2019). When the relative strength of these forces that damage the fruit is relatively high, the fruit will be damaged by the shallow surface, and due to the repeated action of the external force, the connection force between the fruit cells and the strength between the cells will change, resulting in brittleness or plasticity of the fruit injury makes the fruit soft (Wei et al, 2019;Zhou & Wu, 2018). Directly damages the plasma membrane of the damaged area, softens it and reduces its oxidation resistance (Cliff & Toivonen, 2017).…”
