“…In 2019, high performance liquid chromatography (HPLC) with tandem mass spectroscopy was used to detect corn stigma, chrysanthemum, and safflower as adulterants in saffron, through the identification of the components of allantoin, chlorogenic acid (ChA) and hydroxysafflor yellow A (HSYA) (Kong et al, 2019). Using this technique, along with gel permeation chromatography (GPC), Sudan dyes were detected in Egyptian spices with a limit of quantification of 0.1 mg/kg (Sebaei et al, 2019).…”

Solvent‐free mechanochemical preparation of graphene oxide–Fe3O4 and its application in magnetic dispersive solid‐phase extraction of illegal dyes in food samples

“…Several analytical techniques have been reported for the determination of these yellow cationic dyes in different food samples (e.g., UV-Vis, surface-enhanced Raman spectroscopy, HPLC, and LC-MS) [10][11][12][13][14][15][16][17][18]. Among them, widely accessible HPLC has attracted considerable attention due to its remarkable precision, accuracy, high separation efficiency, and reliable performance.…”

Surface-enhanced Raman scattering using flower-like Ag/ZnO as active substrates for the label-free and sensitive detection of rhodamine 6G and melamine

“…3 Synthetic dyes, such as rhodamine 6G and rhodamine B, are added to some products as color enhancers. 4,5 Rhodamine 6G is a synthetic industrial dye used for dyeing, coloring, and polishing textiles, leather, wood, and other industrial products. 6 However, because rhodamine 6G is bright in color, strong in coloring power, and low in price, some producers illegally use industrial dyes to improve the appearance of food, making inferior foods look superior, which endangers consumer health.…”
