摘要：

Two independent methods were developed to identify and determinate synthetic dyes and to follow their degradation processes. The IP-RP-HPLC method was optimised by the experimental design technique and the results obtained were compared with ones obtained by direct/derivative spectrophotometry. The dyes considered in this study that are representative of soft drink components, are: Tartrazinc (El 02), Quinoline Yellow (E 104), Sunset Yellow (E I 10), Carmoisine (E 122), Amaranth (E 123), New Coccine (El 24), Patent Blue Violet (E 13 1), and Brillant Blue FCF (E 133).
