The sample MD13 had the highest concentration among the
others, containing 75.30 ± 3.85 mg L1 of INS 102 colorant. A curious
fact is that some manufacturers report that their product contains
a particular colorant although our method identified and
quantified a different one and sometimes there was no synthetic
colorant. As an example, in the samples Y7, MD12 and MD15 the
colorants were not identified or the values were below the limit
of detection for all colorants studied in this work.
