Optical and electrical methods for the non-destructive measurement of food quality

We have applied optical and electrical methods for the non-destructive measurement of food quality. We have mainly focused on fresh fruit and on diffuse reflectance spectroscopy, but other methods anf food were also been used.

Diffuse reflectance spectroscopy is a technique where the sample is illuminated by white light and part of the photons diffusely reflected by it are collected and analyzed in a spectrometer.

We employ this technique to infer the internal quality of fruit in a non-destructive way.


Detection of fruit and tree pathologies from optical measurements

We have mainly applied fluorescence to the study of scald in 'Rocha' pear.

We are currently starting a research line on the use of diffuse reflectance and transmittance spectroscopies to the detection of other pathologies in fruit trees and in cork tree.


Light scattering

Light scattering plays an important role in light propagation in biological media. Hence, we have also a research line devoted to the study of more fundamental aspects of light scattering, not only in biological tissue, but in turbid media, in general.

Applications of single scattering for particle sizing were also envisaged in the past.
