Animal and vegetable fats and oils - Cocoa butter equivalents in cocoa butter and plain chocolate - Part 1: Determination of the presence of cocoa butter equivalents (ISO 23275-1:2006)

ISO 23275-1:2006 specifies a procedure for the detection of cocoa butter equivalents (CBEs) in cocoa butter and plain chocolate by high-resolution capillary gas liquid chromatography of triacylglycerols and subsequent data evaluation by regression analysis. The method is applicable for the detection of 2 % CBE admixture to cocoa butter, corresponding to about 0,6 % CBE in chocolate (i.e. the assumed fat content of chocolate is 30 %).
