Advanced Spectrophotometric Analysis of Sunset Yellow Dye E110 in Commercial Food Samples

Disposable Electrochemical Sensor for Food Colorants Detection by Reduced Graphene Oxide and Methionine Film Modified Screen Printed Carbon Electrode

“…Due to high sensitivity, high specificity, low cost, short time analysis, and simplicity, electrochemical methods were widely proposed for food dyes determination instead of conventional methods, i.e., spectrophotometry [ 10 , 11 ], chromatography [ 12 ], and capillary electrophoresis [ 13 ]. According to azo and hydroxyl group of azo dyes, direct voltammet-ric determination is divided into 2 categories including cathodic reduction and anodic oxidation.…”

Nitrogen-doped biomass-derived carbon dots for fluorescence determination of sunset yellow

“…3C demonstrate that the emission wavelength of N-CDs is influenced by the excitation wavelength, resulting in a red-shift as the excitation wavelength increases. 48 The QY of N-CDs was calculated to be 10.63%.…”

“…These methods include high-performance liquid chromatography (HPLC), 10 electrochemical methods, 11,12 near-infrared spectroscopy, 13 and spectrophotometric analysis. 14 However, these approaches have signicant limitations such as expensive instruments, complex sample preparation, and high testing costs, rendering them ineffective. Thus, there is an urgent requirement to develop a method that necessitates simple sample preparation and employs reliable yet uncomplicated instruments.…”

A modified electrode based on a 3D reduced graphene oxide and MoS2 composite for simultaneous detection of sunset yellow and tartrazine

“…[1][2][3] To ensure food safety and consumer condence, it is of great signicance to have reliable and accurate monitoring of SY and TZ content in foods. Although multiple analytical methods based on optical signals [4][5][6] can be used for individual detection of SY and TZ in food samples with high sensitivity, these two colorants are usually used together in most foods. Thus, it is necessary to develop analytical methods that can simultaneously determine them.…”
