Evaluation of a Kiwifruit non-destructive firmness sensor

Abstract

Non-deslructive firmness sensors have recently become available for packers and f r u í handlers although they derrand more ¡nforrratbn on their performance and reliability. A corrmerdal sensor based on low rrass irrpact has been tested on kiwifruit. Correlatton betweer the firrmess Índex given by the device and Magness-Taybr foro» was low (r3 = 0.594). Classiftoatbns modeled with dbcrirrinant analysls showed that it Is feasible to sort samples Into two firnness groups (96 to 91%), but dassiflcatbn into three dasses yields lower scores
