Cocoa, Chocolate, and Confectionery Researchers

The mission of the Cocoa, Chocolate, and Confectionery Research Group is to serve confectionery manufacturers and consumers by conducting research pertinent to this large and dynamic segment of Pennsylvania's food system.

Consistent with the student-centered philosophy of the Department of Food Science, this research will be conducted primarily in the context of graduate education; consequently, an important function of the group is to develop well-educated employees for the confectionery industry. Through an emphasis on collaborative and creative research, the Cocoa, Chocolate, and Confectionery Research Group will achieve international recognition as a center of excellence in cocoa, chocolate, and confectionery science and technology. 


The objectives to fulfill our mission are:

  • to maintain high-quality graduate research
  • to maintain relationships with organizations that share an interest in chocolate and confectionery (e.g., AACT, CMA/ACRI, NCA, PMCA, DMI, USAID, USDA), and the confectionery industry
  • to encourage a collaborative approach to research on cocoa, chocolate, and confectionery
  • to strengthen interdepartmental and intercollege research collaboration
  • to promote the transfer of research findings through the sponsorship of an international seminar and the presentation of short courses
  • to encourage presentations at national and international meetings.
