Abstract

Zinc, boron, iron, magnesium, calcium, sodium and silicon were determined in aniseed drinks by inductively coupled plasma-atomic emission spectrometry (ICP-AES). These elements were considered as chemical descriptors to characterise Spanish-certified aniseed drinks brands of origin. Different pattern recognition (PR) procedures were applied for these purposes. This chemometric study have included methods like principal component analysis (PCA), non-supervised PR techniques such as cluster analysis (CA), supervised PR methods of hard modelling like linear discriminant analysis (LDA) and soft independent modelling of class analogy (SIMCA).
