Abstract

In order to respond to the food industry and agriculture needs of on-line control, a NIR spectrometer was developed and coupled with optical fibers. Silica and fluoride glasses were tested. Different geometrical configurations of the optodes were used and compared. The aim was to measure non-destructively the sugar of the fruit (apples and nectarines) and the humidity of the flour. Good results were obtained on the nectarines (sugar) and on the flour (humidity) but the determination of the sugar content of the apples was not satisfying. The depth of penetration of the light and the influence of fruit firmness on spectral characteristics are also discussed.
