Multivariate class modeling for the verification of food-authenticity claims

Description

Food authenticity is a challenging analytical problem normally addressed using sophisticated laboratory methods that 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?" .We recommend class-modeling methods to answer this type of question and discuss the principles, the practice and the results of several types of such methods. We also compare them, in terms of advantages and short-comings, with the discriminant-classification approach. © 2012 Elsevier Ltd.
