The legislation on Flavourings and Flavouring Substances is constantly evolving (1998, 2008, 2012) and extremely complex due to the large number of ingredients and processing procedures.

A premise : the term "Aroma" or "Flavourings" is generic, so it does not mean that the flavouring or flavourings included are obtained by natural means, but is a mixture of substances or preparations, obtained by synthetic, i.e. chemical, transformations.

Explanation :

Whether the term is "Aroma" or "Flavourings", it is a chemical component that replicates the taste of the ingredient, but may have no ingredient substance.

Flavourings: products not intended to be consumed in their original form, which are added to food in order to impart or modify an aroma and/or flavour. They are manufactured with or contain the following categories of substances: flavouring substances, flavouring preparations, thermal process flavourings, smoke flavourings, flavour precursors or other flavourings or mixtures of flavourings.
