Verification of food authenticity is a complex issue that generally involves the determination of many physical or chemical properties. The best way to get useful information from such data is to process them by multivariate pattern recognition methods, which allow consideration of intercorrelations among variables-a key issue for an accurate...

The present tutorial paper is aimed to analyse and critically discuss the consequences of row pre-processing (conversion of measurement units, derivatives, and standard normal variate transform) on the evaluation of final outcomes of chemometric data analysis. An in-depth focus on pre-processing effects both on the signal shape and on...

In this paper, a novel voltammetric/amperometric approach for the direct determination of free acidity (FFA, expressed as mass percentage of free oleic acid) in olive oil samples is presented. The method is based on the reduction processes occurring at a platinum microdisk electrode involving the free fatty acids present in the matrices. To...
