Damage to onions caused during harvest and postharvest handing can lead to serious quality losses. The identification of sites contributing to cuts, bruises, etc has been made more objective by new technology. The Instrumented Sphere Model 100 is an electronic impact recording device which quantifies the drops and collisions that fruit and vegetables experience during handling. This investigation of Vecon’s handling equipment in Tasmania is the first in Australia to use the sphere for identification of physical causes of onion damage. The sphere enabled a relative comparison of potentially damaging impact sites.
