A method was developed to determine ten artificial food colorants,
commercially accepted in Brazil and other countries, in
The method was validated, and the colorant concentration in
the samples varied from 0.89 to 75.30 mg L1 for INS 110 and
INS 102, respectively. The concentration of certain artificial colorants
in real samples was below the upper limit of 1000 mg/
100 g. Among the artificial colorants quantified in samples of
yogurt and milk drinks, INS 122 was identified in 33% of samples.
The method developed proved specific for artificial colorants but
not for the natural colorant Annatto
