Electrochemical Assessment of Coffee Qualities | Christopher H. Hendon

This session was presented at Roast Summit on February 22, 2024 in Portland, Oregon.
This talk details the development of an electrochemical method to assess solvated coffee compounds using a three-electrode electrochemical method, performed using either commercial or home-made potentiostats. Dr. Hendon will demonstrate that there is a well-defined relationship between total dissolved solids (concentration of coffee material by mass) and current passed at reducing potentials.
Presenter: Prof. Christopher H. Hendon is a computational chemist with interests in energy materials and coffee extraction. He obtained his BSc. Adv. HONS from Monash University (2011) and PhD from the University of Bath (2015). After a two-year postdoc at Massachusetts Institute of Technology he joined the University of Oregon in 2017 as an Associate Professor of chemistry where his research group focuses on materials with useful defects. He has published over 115 papers, was named a Cottrell Scholar in 2021, a Camille Dreyfus Teacher-Scholar in 2022, the Samuel R. Scholes Jnr. Lecture for excellence in scientific communication, and has been awarded the Rippey Award for Innovative Teaching twice. In coffee, he authored, “Water For Coffee”, and has written numerous peer-reviewed articles on the topic. Presently, he leads a laboratory studying the chemical physics of coffee beverage production.
