IS THE ACOUSTIC RESPONSE OF FRUITS A MEASURE OF FIRMNESS OR OF TURGOR?

Abstract

Non-destructive assessment of fruit firmness by means of measuring the sonic response to impact, has been demonstrated with the Firmalon instrument, developed by Eshet Eilon Ltd. (Israel), based on Galili et al. (1996). Attempts to adapt the instrument for continuous measurement of fruit softening during CA storage, have indicated that there might be factors, other than softening, which are involved in the acoustic response of the fruit.
One of the possibilities herein investigated, was weight loss due to transpiration.
