Because of the many ways food ingredients can be combined, it is not practical to specify
composition of all foods and generally, for foods not listed in the food Standards Code they
contain any approved colouring, flavouring, and texture modifying additives. Processed foods
containing food additives must declare them on the label either by name or number. Most
approved food additives have been allocated a number in the Food Standards Code which
the specific additive to be identified. For example, the designation on a product's label of
(102)' means that the food contains the yellow colouring tartrazine.
Under certain circumstances it is possible that an additive present in a food which is used as an ingredient in the preparation of another food will 'carry-over' without being declared in the ingredient list on the label. For example, if margarine is used in the preparation of a cake, margarine will appear in the ingredient list rather than the individual components of margarine. If you must avoid particular food additives, you should consult the Food Standards Code to be aware of additives that can be present under these circumstances.
