Food authenticity is a challenging analytical problem normally addressed using sophisticated laboratory methods which produce large data sets. Multivariate mathematical methods are required to process such data sets typically to answer a question such as “Is sample X, which claims to be of type A, compatible with type A samples on the basis of its analytical measurements?”. Class-modelling methods are recommended to answer this type of question and the principles, practice and results of several types of such methods are discussed. A comparison, in terms of advantages and short-comings, with the discriminant classification approach is also presented.

Abstract
Food authenticity is a challenging analytical problem normally addressed using sophisticated laboratory methods which produce large data sets. Multivariate mathematical methods are required to process such data sets typically to answer a question such as “Is sample X, which claims to be of type A, compatible with type A samples on the basis of its analytical measurements?”. Class-modelling methods are recommended to answer this type of question and the principles, practice and results of several types of such methods are discussed. A comparison, in terms of advantages and short-comings, with the discriminant classification approach is also presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
