PhD project title

Nuclear Magnetic Resonance (NMR) study of the physico-chemical modifications related to the characteristics of raw materials and transformation processes of foodstuffs: case of coffee beans from Coffea L.


 The project aims at investigating the influence of (1) the variability of the seeds from Coffea L. tree and (2) heat treatment processes (in particular roasting) on the physico-chemical composition of coffee beans and resultant drink after physical division (grinding). It consists in exploring and comparing the capacity of different high resolution NMR approaches to monitor the evolution of coffee composition and identify potential correlations between particular NMR signals and some characteristics of this composition. The ascertained correlations will serve, on the one hand, to identify the reaction mechanisms involved in roasting, on the other hand to optimize manufacturing processes and control product quality.

Candidate’s qualifications and skills

Holding a Master’s degree, the candidate must have significant hands-on knowledge of analytical chemistry techniques and show particular interest in data analysis and calculation. A preliminary knowledge of NMR would also be appreciated. More generally, the applicant will have to be fluent in English and show good capacity of adaptation and communication. This implies scientific rigour, organization skills, ability to work in a team, think critically, synthesize, and make proposals.
