Fluorecence Spectroscopy Detects Fraud in EVOO
Some of you may know that one of my research projects has been to
understand how the fluorescence spectra of olive oils change with age, origin, and exposure to sunlight and oxygen. While my students have done terrific
work over the years - especiall
y SURF student Namita Khanjanchi '19 -
we seem to have gotten scooped by this group from the University of
Madrid. Not to worry too much, though because our techniques were
somewhat different and there is ALWAYS more to know. Perhaps a trip to
Spain is in order?
