VIS/NIR Spectrometry to Predict Fruit Ripeness

A recently developed, non-invasive sensor based on spectral? Optical technology (400 nm to 1100 nm) can be used to predict the fruit chlorophyll content, which provides a valuable information on the fruit chlorophyll prediction is determination of the optimum harvest date and to non-destructively analyse the physiological fruit age during shelf life. Experiments were carried out on apples during 1999-2001 at 3 fruit growing locations (Jork and Werder, Germany; Skierniewice, Poland). The spectral-optical readings were carried out in freshly harvested ‘Elstar’ and ‘Jonagold’ apples. As a reference destructive measurements on SSC, starch and fruit firmness were applied. Apple ripeness stages can be predicted with a standard error of cross validation of 6 days using the spectral data. A second application was developed to discriminate bananas in different ripeness stages, which are commonly used commerically in the market. This apparatus will be shown during the presentation.
