Estimates of maximum limits of food colours use in Brazil through the Danish Budget Method and the Bär and Würtzen-modified method.
The establishment of the permissible levels for the use of additives in foods must be based on the Acceptable Daily Intake (ADI). A method that may be applied for this purpose is the Danish Budget Method which estimates the maximum amount of the additive that may be added to the food based on the functional properties of the additive, and on the categories of the food in which the additive will be used. Based on the latest information Bär and Würtzen propose some modifications to the original Budget Method, one of which is the addition of a correction factor which takes into account the competition between different food additives with the same functional properties. In the present paper, both the Budget Method and the Bär and Würtzen-modified method were applied to evaluate whether the maximum levels of food colours use exceeded their ADI or not. Applying the original Budget Method, the results showed that the colours Sunset Yellow, Amaranth, Erythrosine, Ponceau 4R and Cochineal possibly exceeded the ADI; while applying the modified method only the colours Erythrosine and Cochineal would exceed the ADI. Brazilian regulatory authorities should be advised to establish maximum limits of use for the following categories of colours: Caramel, Inorganic, Natural and Artificial Colours Identical to the Natural Ones, where ADIs have been evaluated by JECFA.
