The importance of nuclear magnetic resonance (NMR) spectroscopy for the
food industry, including the coffee industry, has led to several studies using this
analytical tool to assess coffee in different scenarios. In this context, this chapter
presents an overview of 1H NMR-based metabolomics analysis used in coffee quality
control. Several articles using 1H NMR associated with multivariate data analysis have
been published to investigate aspects related to quality, authenticity, sensory quality,
production processes, and origin of coffee. In addition, the present review reports the
main chemical shifts of the constituents present in the extracts of green and roasted
coffee beans. The results presented confirm the potential and versatility of 1H NMR
combined with chemometric tools for coffee analysis, playing an important role in
distinguishing and identifying the origins, quality, and purity of coffee. Exploratory
data analysis, classification, and calibration are the most used chemometric methods in
metabolomics applied in the coffee field. The results show the potential of NMR and
multivariate data analysis for coffee authentication.
