“…Drops onto a metal surface did not result in changes of titratable acidity ( Figure 5). Reductions in acidity were also determined on 'Royal Gala' apples submitted to drops from a 20 cm height and maintained under refrigerated storage (HENDGES et al, 2011). .…”

“…In addition to visual quality losses, mechanical injuries speed up fruit metabolism, anticipate senescence and reduce postharvest shelf life. Mechanical injuries inflicted by impacts stimulate respiration rates (AGAR; MITCHAM, 2000) and decrease flesh firmness in pears (SINOBAS et al, 1991), reduce titratable acidity (HENDGES et al, 2011) and intensify browning of damaged tissues in apples (MONTERO, 2010).…”

Pears have a very sensitive epidermis and are prone to signal mechanical blemishes, which result in reduced visual quality and low consumer acceptance. The objective of this work was to identify critical points and the magnitude of impact forces on a packing line at a commercial packinghouse. The effect of injuries on ripening and quality of ´Packham´s Triumph´ pears was also evaluated after cold storage. The packing line was scrutinized on its transfer points, fruit drop heights and cushioning overlays, which allowed to acquire the maximum accelerations on each spot. The maximum acceleration forces were reproduced in the lab with ‘Packham’s Triumph’ pears to evaluate the effects on fruit quality after cold storage. Four critical points were noticed on the packing line: at the transfer from the conveyor belt to the lifting rollers, at the transfer from the lifting rollers to the washing ramp with rotatory brushes, at the entrance to the singulator at the end of the conveyor belt and at the drop from the sizer to the packing stalls. Ripening of ‘Packham’s Triumph’ pears invariably came about during cold storage, and independently of the imposed impacts. The impacts under the circumstances of the test did not affect the quality of ´Packham´s Triumph´ pears kept for up to 120 days at cold storage followed by five days at room temperature.
