For the olive industry it is important to be able to rapidly and accurately determine fat and moisture in the purchased olives and olive pomace after crushing. To ensure fair payment of raw materials, know potential oil yield and optimize extraction to retain as much high value oil as possible.
The Near Infrared Reflectance (NIR) technology is highly suitable for these measurement purposes. NIR is an indirect analytical method, were the relationship between reference values and the spectra of the samples are related using multivariate calibrations. Instead of the time consuming and labor intensive traditional wet chemistry methods, with NIR the multi-component analysis is done in seconds without use of any chemicals or consumables.
