Foreign fats in chocolate

Discontinued activity

The so-called Chocolate Directive (Directive 2000/36/EC) allows the addition of up to 5% of vegetable fats other than cocoa butter, the so-called cocoa butter equivalents (CBEs), in chocolate. If CBEs are added, consumers have to be informed by appropriate labelling. EU Member States' laws, regulations and administrative provisions have had to comply with the Chocolate Directive since August 2003.

Assessing compliance of chocolate products with the labelling provisions cannot be done without appropriate methods of analysis. The chemical composition and physical properties of the CBEs resemble those of cocoa butter very closely, making them extremely difficult to quantify and in some cases even difficult to detect. The JRC has developed a reliable analytical approach to detect and quantify CBEs in dark and milk chocolate. The methods have been validated in international trials and reported in three reports ( Validation of a method for the detection of cocoa butter equivalents in cocoa butter and plain chocolate file [336 KB] , Validation of a method for the quantification of cocoa butter equivalents in cocoa butter and plain chocolate file [181 KB] , Validation of an analytical approach to determine cocoa butter equivalents in milk chocolate file [1 MB] ).

To facilitate deployment of this approach for the analytical chemist, two toolboxes named CoCal-1 and CoCal-2 have been established by the JRC. The toolboxes are built on scientific research and enable the enforcement of Directive 2000/36/EC.

The JRC also carried out a survey on the correct labelling of foreign fats in dark and milk chocolate samples acquired from the European market using CoCal-1 and CoCal-2.

CoCal-1 for dark chocolate

CoCal-2 for milk chocolate

  • a standardised database covering compositional information on a wide range of authentic milk fat samples, and more than 900 mixtures thereof with other chocolate fats,
  • a description of a validated method file [1 MB] for the detection and quantification of milk fat and CBEs in milk chocolate,
  • a certified cocoa butter reference material (IRMM-801), and
  • an electronic evaluation sheet file [740 KB] to calculate the final result.
