Last modified: 20/12/2017

The MeBioS Biophotonics group at the KU Leuven Department of Biosystems investigates the physical properties of biological materials to develop new technologies for the agro-food chain. The fundamental research activities focus on measurement of the optical properties and exploitation of this information to develop novel sensor technologies. In our applied research these techniques are combined with advanced statistical techniques for quality assessment and optimization of agro-food products.

Project

 

As harvested fruit are living organisms, they remain metabolically active. This means that they consume oxygen to convert sugars into energy to sustain their tissue functions. Apart from the metabolic processes to sustain the tissue functions, the enzymatic ripening processes also remain active. To slow down these ripening processes many fruit are stored under a controlled atmosphere, involving low oxygen concentrations. However, if the oxygen availability for an individual cell is too low, the cell will die, resulting in the formation of postharvest defects (browning and cavities). Therefore, optimizing the gas concentrations in fruits is an important field within postharvest research. In this context, it would be very valuable if we would be able to measure the porosity of an intact fruit as an indicator for the gas diffusivity.

 

Spatially Resolved Spectroscopy (SRS) combines multiple spectroscopic measurements with light propagation models to separate the information on light scattering by the microstructure and absorption by the chemical composition. Accordingly, SRS has high potential for non-destructive physical and chemical characterization of turbid media. Therefore, the main goal of this PhD research is to develop a non-destructive SRS sensor for measuring the porosity of pome fruit (apples, pears,…) as an indicator for the storage potential.
