P1H-6 Ultrasonic Structural Quality Control of Swiss-Type Cheese

A study on ultrasonic structural quality control of Swiss-type cheese using 1-2 MHz longitudinal pulse echo is presented. The aim was to prove the feasibility of detecting cheese-eye size/distribution and ripening induced defects. A normal C-scan can be used to assess the interior structure of the cheese non-destructively. Image analysis combined with ultrasonic modalities provides potential for quantitative defect characterization and thus allows structural quality assurance of cheese. Ultrasonic structural quality assurance, foreign body detection and ripening stage monitoring could be appended into a single inexpensive device with good potential to be implemented on-line
