Current Research Projects:

An underlying need of citrus juice processors is to increase the value of the harvested crop, particularly through discoveries of new, value-added uses of waste peel.  There are various candidate components of peel that can be explored, but the ones investigated by this team are the bioactive small molecule constituents.  Emphasis is placed on the flavonoids, hydroxycinnamates, coumarins, furanocoumarins, although this list does not serve to exclude other possible marker, and/or bioactive constituents discovered in a variety of screening programs in place.
