Coffee quality gene finally identified.

 

February 7, 2007 - Thanks to researchers at CIRAD at the University of Campinas, Brazil - were now closer at fully understanding what exactly makes a coffee "specialty". Since 2001, the CIRAD group has worked on a joint project to understand what compounds play an important role in coffee quality.

According to the research, it is the accumulation of sucrose - or common table sugar - that plays a critical role in the development of desirable organoleptic quality. Initiated by the enzyme - sucrose synthetase - sucrose slowly accumulates in the tissue of the plant during ripening and right before picking. During roasting these compounds react to form important flavor and aroma compounds.
