Food PDO verification is a food authenticity issue. It is a challenging analytical problem normally tackled using complex laboratory techniques which produce large or very large data sets. Multivariate mathematical methods are required to process such data sets. A typical question which arises in these applications is “Is sample X, which claims to be of type A, compatible with type A samples on the basis of its analytical measurements?” Class-modelling and discriminant methods have been used to answer this type of question in the past. In this chapter, the principles, practice and results of several types of a number of such methods are discussed in terms of advantages, shortcomings and reported analytical success.

Abstract
Food PDO verification is a food authenticity issue. It is a challenging analytical problem normally tackled using complex laboratory techniques which produce large or very large data sets. Multivariate mathematical methods are required to process such data sets. A typical question which arises in these applications is “Is sample X, which claims to be of type A, compatible with type A samples on the basis of its analytical measurements?” Class-modelling and discriminant methods have been used to answer this type of question in the past. In this chapter, the principles, practice and results of several types of a number of such methods are discussed in terms of advantages, shortcomings and reported analytical success.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
