Abstract

In previous papers, six cocoa butter equivalent (CBE) samples were considered to carry out a study about the detection of their presence in cocoa butter (CB). In this work the % fatty acid (FA) compositions of triacylglycerol (TAG) subfractions separated by Ag+-High Performance Liquid Chromatography (Ag+-HPLC) from CB, CBE and CB/CBE mixtures were investigated. The fully saturated (SatSatSat) TAG subfractions isolated from CB, CBE and CB/CBE mixtures were the most suitable for the aim of the research. In fact, the multiple regression models obtained using the % FA composition of SatSatSat subfractions permitted to carry out effective CBE detections. In the present work the attempt to improve the statistical approach using as variables the results of the stereospecific analysis of the TAG fraction and of its main subfractions from CB, CBE and CB/CBE mixtures is described.
