ShareSome interactions between fruit firmness and its measurements.
Author(s) : CHEN H., VERSTREKEN E., BAERDEMAEKER J. de
Summary
The previously used destructive firmness measurement techniques are reviewed in the paper. Magness-Taylor firmness, static elastic modulus and dynamic elastic modulus of apples were measured and compared for their reliability in correlation with the acoustic resonant frequency. The dynamic elastic modulus is suggested as a reference value for developing nondestructive dynamic techniques. As external factors affecting the firmness measurements, the compression speed in the quasi-static test, loading mass in the dynamic test, and sample shape were studied. The influence of temperature of the apple on firmness was also investigated.
