Analysis of olive paste with FT-NIR spectroscopy

The vast majority of olives grown all over the world are used for the manufacture of olive oil. The value of an olive crop is mostly determined by the oil content. Depending on the time of the harvest and the olive variety, the olive oil content may vary between 10 – 30%. To determine the exact oil content is essential for the farmers and the industry alike to estimate the value of a harvest.

Traditional wet chemical methods, e.g. Soxhlet analysis become increasingly unacceptable in the laboratory since they require large amount of solvents, creating health and safety risks as well as environmental issues. Furthermore, the measurement results are often operator dependent and the procedure is slow.

Benefits of FT-NIR Spectroscopy

With FT-NIR, the ground olives are analyzed in less than a minute, using no harmful chemicals or solvents. Simply put the sample into a petri dish and place it on the instrument. With only one measurement, not only the fat and moisture of the olives can be measured, but also the acidity can be assessed at the point of delivery, a criterion for good manufacturing practice during the harvest and the storage of the olives.

Bruker Optics developed ready-to-use calibrations for a quick and efficient start with FT-NIR technology.
