Mechanical Damage Of Strawberry During Harvest And Postharvest Operations

Abstract

Strawberry is a non-climacteric fruit with a limited harvesting period. Because of high susceptibility to mechanical damage, strawberry has a small postharvest life. In this research, an experiment was designed to study the mechanical damage phenomena in strawberry during the harvest and postharvest operations together with some physical properties of strawberry. Influences of some other factors such as variety, fruit position in the box as well as box position on the truck were also investigated. Results indicated that the variety, operation stage, fruit position in the box, and box position on the truck, had significant effects on the extent of the fruits' mechanical damage. Maximum damage index was related to picking stage. The variety Gaviota showed more susceptibility to mechanical damage than Selva. The maximum damage occurred at the bottom rows in the boxes. Furthermore, it was observed that the higher the position of a box on the truck, the more the susceptibility of fruits would be to mechanical damage.

Reduce Loss during Transportation: A Case Study of Fresh Vegetables in Thailand

“…For example, using the plastic board as a layer to keep vegetable inside the container can increase the air flow and reduce the compression and impact due to full packing. In addition, the worker should put delicate vegetable on the lower position in the back of the loaders to avoid the damage from the vibration of the truck [2].…”

Postharvest decay of strawberry fruit: Etiology, epidemiology, and disease management

“…For this reason, strawberry fruit are harvested and often packaged in the field. Aliasgarian et al [18] studied the mechanical damage of strawberry fruit during harvest and postharvest operations, together with some of their physical properties. The results indicated that the variety, operation stage, fruit position in a box, and box position on a truck, have significant effects on the extent of the mechanical damage to the fruit.…”

Proporciones de daños mecánicos y su efecto en calidad postcosecha de aguacate ‘hass’

“…Cajas, frutos y daños mecánicos por cuadrilla y hora de cosecha de aguacate 'Hass'. Los resultados coinciden con los valores reportados en otros cultivos como mango (Mazhar et al, 2011), fresa (Aliasgarian et al, 2015), naranja (Miranda et al, 2015) y toronja (Pérez et al, 2002), donde los daños mecánicos son considerados como un tipo de estrés, como consecuencia de una inapropiada cosecha, manipulación y técnicas de transporte del fruto durante la cosecha y postcosecha. Estos autores señalan: los daños más comunes son las cortaduras, desgarraduras y magulladuras ocasionadas por impactos, compresiones y vibraciones.…”

“…El fruto de aguacate 'Hass' es muy susceptible a daños externos y mecánicos ocurridos en pre y postcosecha (Hodges y Toivonen, 2008), lo cual resulta en una reducción de las propiedades sensoriales, nutrimentales, constituyentes químicos, propiedades mecánicas y funcionales de los frutos (Aliasgarian et al, 2015). Durante la precosecha, el aguacate Hass está expuesto a condiciones climáticas adversas que reducen la calidad del fruto en madurez de cosecha (Sharma et al, 2014) y el comportamiento postcosecha, está directamente relacionado con la tolerancia a este estrés natural o inducido durante la precosecha (Mazhar et al, 2011).…”

“…The avocado 'Hass' fruit is very susceptible to external and mechanical damages occurring in pre and post harvest (Hodges and Toivonen, 2008), which results in a reduction of the sensorial, nutritional, chemical constituents, mechanical and functional properties of the fruits (Aliasgarian et al, 2015). During pre-harvest, Hass avocado is exposed to adverse climatic conditions that reduce fruit quality at harvest maturity (Sharma et al, 2014) and post-harvest behavior, is directly related to the tolerance to this natural or induced stress during preharvest (Mazhar et al, 2011).…”
