Original Abstract

An investigation has been made to establish the basic relationship between the mechanical resonance, firmness, chemical composition and ethylene production during the maturity time and the ripening time of peach fruit. The non-destructive frequency response technique has been evaluated and the stiffness coefficient has been calculated to obtain the firmness of peach fruit. From the evaluation of ethylene production at the beginning of onset of climacteric ripening phase the stiffness coefficient is within 6 Hz/g - 10 Hz/g. The ripening phase of the fruit over the ripe stage gives the lowest value of the stiffness coefficient. The correlations between the results obtained by mechanical resonance method and other methods show very good matching
