Abstract:

During transport and handling, apple fruits are subjected to various loading conditions that may lead to damage and bruising. To develop improved methods for assessing and predicting apple bruising caused by repetitive impact loads during the course of transport and handling, impact pressure and fruit bruising using a pressure-sensitive film technique were measured by a simple drop test. As the impact test, apples were dropped from different heights for a certain number of times. Both bruising areas and volume increased relative to the dropping height and the number of drops. For the different number of drops, significant difference in bruising area or volume was found as a result of dropping height. Thus, impact force and pressure between the apple and the impact surface were analysed in order to assess and predict apple bruising. Pressure-sensitive film results showed significant differences in the impact of apples dropped multiple times from different heights onto a rubber counterface surface. The results indicate that bruising area and volume can be assessed and predicted by regression models based on the impact force obtained from the pressure-sensitive film (F_PSF). The coefficients of determination (R²) for bruising area and volume were found to be 0.97 and 0.98, respectively.
