Destructive and non-destructive evaluation of peach firmness

Popis výsledku v původním jazyce

The firmness of peach fruit ("Red haven") was monitored during 5 weeks within its harvesting period. Non-destructive impulse response and destructive Magness-Taylor puncture tests were used. Non-destructive impact was realized by the free falling bar. After impacting, the peach response has was measured in terms of the surface displacement and/or surface velocity. The peach response was evaluated both in time and frequency domain. The correlation between response frequency and physical parameters of thepeaches was analyzed. The dominant frequency, stiffness coefficient and elasticity coefficient as a function of time can be expressed as a decreasing, nearly linear function. The impulse response is more sensitiv to firmness changes than the Magness --Taylor firmness test. When determining fruit fitness, the non-destructive impulse response test could replace conventional destructive tests.
