• Spectroscopy of Food and Agricultural Products

02 res

Development of new spectroscopic 'non destructive' methods to investigate the chemical composition of food and agricultural products. Optimization of spectroscopic methods to quantify minor components of food matrices. Main actual studies concern the quantification of pigments in olive oils and other seeds oils by means of UV-vis spectroscopy; the study of honey and pollens by means of front-face fluorescence in order to identify spectral profiles specific for the botanic and geographic origin; the combination of spectroscopic techniques to study the anti-oxidant activity of wine and other beverages. Other topics: investigations of specific frauds and adulteration of food and agricultural products; develoment of portable spectroscopic devices.
