Summary: Pattern recognition techniques - cluster, principal component, factor and canonical discriminant analysis, were used for differentiation of cheese species using such elemental markers as Ba, Cr, Cu, Hg, Mg, Mn, Ni and V. Cluster analyses showed some preliminary results intimated partial species differentiation of cheeses. Principal component and factor analysis appeared to be effective methods not only for data visualisation but for efficient differentiation of cow and sheep cheese species as well. Canonical discriminant analysis demonstrated a 95% potential to distinguish differences and correct classification of cheese species according to the used specific elemental data.
