Toward the Determination of the Geographical Origin of Emmental(er) Cheese via High Resolution MAS NMR: A Preliminary Investigation

Abstract

We tested the potential of High-Resolution MAS NMR spectroscopy to study 20 samples of Emmental cheeses from 7 different geographical regions. Principal component analysis (PCA) and discriminant analysis (DA) were used to analyze the data set of 1H HRMAS NMR spectra and succeeded in grouping the studied samples according to their geographical origins.
