Application of infrared spectroscopic techniques to cheese authentication: A review.

Infrared spectroscopy has been shown to be efficient in cheese authentication due to the advantages of high sensitivity and speed of analysis, especially when associated with chemometrics. This review discusses approaches on the authenticity, the principles of near‐ and middle‐infrared techniques and the importance of chemometrics for cheese authentication. The spectroscopic techniques proved to be promising for the cheese geographical origin identification, analysis of adulterants and monitoring of maturation stages. The application of principal component analysis, partial least squares and linear discriminant analysis associated with spectroscopy has provided powerful tools for the cheese authentication.
