Abstract
Electrical impedance measurements were used to assess the amount of bruising sustained by a ‘Granny Smith’ apple, and to monitor the development of the bruises over time. A bruise index was developed to quantify the severity of bruising. It was found that the bruise index could distinguish apples bruised to different levels and that there was no significant change in the impedance properties of the apple after the initial damage had occurred. The method described here may have a potential use in assessing fruit bruises.Keywords
