Abstract
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: Tartrazine (E102), Quinoline Yellow (E104), Sunset Yellow (E110), Carmoisine (E122), Amaranth (E123), New Coccine (E124), Patent Blue Violet (E131), and Brillant Blue FCF (E133)File | Dimensione | Formato | |
