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); German version EN ISO 23275-1:2008
This part of ISO 23275 specifies a procedure for the detection of cocoa butter equivalents (CBEs) in cocoa
butter (CB) and plain chocolate by high-resolution capillary gas liquid chromatography (HR-GC) 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 %).
