03 Feb Laser oil analysis

Using laser diodes and algorithms, researchers at the Complutense University of Madrid (CUM) and the Scintillon Institute developed a sensor that can be used to detect fraudulently labeled bottles of olive oil.

The technology is based on fluorescence spectroscopy. After irradiating the olive oil samples with a laser diode, radiation spectra are collected. These radiations, which are the light emitted by olive oil molecules after they have been irradiated by a laser diode, are unique and reflect the different concentrations of pigments that make up each of the molecules. For spoiled or diluted oils, the emission spectrum is different from pure extra virgin olive oils. The radiation spectra analyzes the computer according to the algorithms created by this group of scientists.

This technology serves to identify damaged goods and unscrupulous manufacturers. Sensors have not yet been used in industry, the prototype is still being tested in Spain.
