Elasticity characteristics of fruits.

ABSTRACT :

 

Fruit firmness is evaluated by considering elasticity characteristics. 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 below the inflection point of the stress-strain curve, this coefficient can be measured by a nondestructive 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 modulus of elasticity) with apple and tomato. It is concluded that the coefficient is a good measure of fruit firmness in both scientific and practical evaluation.
