About the Program


Interested in scientific research and in making a difference in the livelihood of smallholders? You can achieve both through scientific research on cacao fermentation in beautiful tropical Costa Rica. 

Very few realize that cacao needs to be fermented before it is converted into chocolate. Cacao fermentation ultimately determines the market value of the cacao beans. Unfortunately, there is insufficient understanding and scientific characterization of the biochemical processes involved in cacao fermentation. Smallholders are typically not paid the full potential value of their beans because they sell them unfermented. Companies that consolidate and ferment beans cannot control well the fermentation process due to the lack of robust scientific information. Through this interdisciplinary IRES, students will gain an in-depth understanding of scientific research and cacao processing. Participants will learn analytical techniques, carry out field and laboratory research, and apply statistical tools to maximize the value of local cacao products. In addition to the research experience, this IRES participants interact with cacao farmers and chocolate manufacturers and will have the opportunity to visit mesmerizing landscapes and learn about the history and culture of Costa Rica. 
 
This program engages students in a highly collaborative and diverse research environment involving research mentors at the Universidad Nacional in Heredia, Food Quality and Innovation Laboratory, Costa Rica (adjacent to San Jose, the capital city) and researchers from the University of Georgia, Department of Food Science and Technology and from the University of Florida, Department of Agricultural and Biological Engineering. 

Please contact José Reyes De Corcuera (jireyes@ufl.edu) for additional information on the program and how you can participate!

Participant selection will be completed in February. A predeparture workshop in which participants will learn the logistics of the program as well as the scientific background necessary for a successful program will be run in March.
