Evaluation of a Non-Destructive Impact Sensor to Determine On-Line Fruit Firmness

A non-destructive impact sensor to measure on-line fruit firmness was evaluated. This sensor is an adaptation of a static model used in the laboratory to measure fruit quality and was installed in an experimental fruit packing line with a commercial sizer chain. The firmness index is related to the...
