Abstract:

During transport and handling, apple fruits experience a variety of loading conditions that potentially lead to damage and bruising. New methods were analyzed for assessing and predicting apple bruising that occurs in corrugated fiberboard boxes due to impact loads during the course of transport and handling. Impact pressure and bruising of apples using a pressure-sensitive film technique were measured by a simple drop test. The statistical incidence of damage and damaged areas for the apples in two types of commercial corrugated fiberboard boxes after being subjected to dropping impact loads were compared: single-wall corrugated fiberboard box and double-wall corrugated fiberboard box. The percentage of damaged apples in the single-wall and double-wall corrugated boxes increased with the increase in drop height; the damage to apples in the lower layer of both boxes was notably higher than that in the upper layer. The images of the pressure-sensitive films showed significant differences in apples impact in both types of boxes. The pressured area of apples in the single-wall corrugated fiberboard box was greater than that in the double-wall corrugated fiberboard box. For both boxes, the pressured area increased on the pressure-sensitive film with the increase in drop height. The average pressure in the single-wall corrugated fiberboard box was slightly greater than that in the double-wall corrugated fiberboard box. In the case of both boxes, no significant change in the average pressure was found as a result of drop height; the change in the average pressure between the upper and lower layers was also not significant. The results indicate that the impact force obtained from the pressure-sensitive film (F_PSF) can be used to assess and predict apple bruising that occurs in corrugated fiberboard boxes. The coefficients of determination (R²) for single-wall, double-wall and both corrugated fiberboard boxes were 0.94, 0.85 and 0.86, respectively.
