Relationship of sonic resonant frequency to compression tests and Magness-Taylor firmness of apples during refrigerated storage.

Type of article: Article

Summary

Apple growers and packers need to measure firmness, preferably using nondestructive measurements. Resonant frequencies and stiffness coefficients were most highly correlated with compression slope, then area, then maximum force. Correlation coefficients decreased progressively from Golden Delicious to Delicious to York Imperial apples, the same progression as the deviation from spherical symmetry and the textural change during ripening and storage.
