Abstract

The objective of the paper reported herein is to determine elasticity characteristics of fruits for the evaluation of fruit firmness.

The coefficient of elasticity – the ratio of the compressive stress to the deformation – was introduced to characterize the firmness of the fruit.
Since the deformation is limited to a value that is below the inflection point of the stressstrain curve, this coefficient can be measured by a non-destructive method.
Tests were performed with different penetrometers and good correlation was found between the coefficient of elasticity and other properties – bioyield and rupture stresses and the Young’s modulus of elasticity – with apple and tomato.

The coefficient can be used as a good characteristic of fruit firmness for either scientific or practical evaluation.
