Abstract

Non-destructive firmness estimation of fruits has recently become available for packers, although they demand more information on their performance and reliability. A commercial device based on low mass impact has been tested in this work, and it has been applied on pears. Correlation between the firmness Índex gíven by the device and Magness-Taylor forcé was low (r=0.896). Classifications modeled with discrlmínant analysis showed that it is feasible sort samples into two firmness groups 96 to 91 % of correct classification for pear). Classification into three classes yields lower scores. A study searching for sources of variation ¡n the measurement showed that the distance sensor-fruit, the displacement from the center, and the operating pressure affect the reading ¡n a significant way.
