Determination of oil and water in olive and olive pomace by NIR and multivariate analysis

Abstract

Fourier transform (FT) Near Infrared Spectroscopy (NIR) spectrometry in combination with partial least squares (PLS) regression was used for direct, reagent-free determination fat and moisture content in milled olive and olive pomace. The two calibration models obtained were built with samples from two years harvest (2006/2007) and have a good predictive power considering the nature of the samples and are both being used in an industrial plant.
