Determination of banned 10 azo-dyes in hot chili products by gel permeation chromatography-liquid chromatography-electrospray ionization-tandem mass spectrometry.

J. Chromatogr. A. 1164(1-2) , 120-8, (2007)

An accurate method based on the use of gel permeation chromatography (GPC)-liquid chromatography-tandem mass spectrometry interfaced with electrospray ionization (GPC-LC-ESI-MS/MS) was devised for the simultaneous determination of Sudan (I-IV), Sudan Orange G...

Development and validation of a confirmatory HPLC method for simultaneous determination of Sudan dyes in animal tissues and eggs.

J. Chromatogr. Sci. 48(1) , 63-7, (2010)

A simple and sensitive high-performance liquid chromatography (HPLC) analytical method for the simultaneous determination of six Sudan dyes (Sudan Red G, Sudan I, Sudan II, Sudan III, Sudan Red 7B, Sudan IV) in animal tissues and eggs was developed. Samples w...

Analysis and testing of biological stains--the Biological Stain Commission Procedures.

Biotech. Histochem. 77(5&6) , 237-275, (2002)

Photocatalytic degradation of Azure and Sudan dyes using nano TiO2.

J. Hazard. Mater. 149(3) , 725-34, (2007)

The present study investigates the dependence of photocatalytic rate on molecular structure of the substrate that is degraded. The photocatalytic degradation of Azure (A and B) and Sudan (III and IV) dyes, having similar structure, but different functional gr...

A simple 2-directional high-performance thin-layer chromatographic method for the simultaneous determination of curcumin, metanil yellow, and sudan dyes in turmeric, chili, and curry powders.

J. AOAC Int. 91(6) , 1387-96, (2008)

A method using simple extraction and 2-directional high-performance thin-layer chromatography (HPTLC) was developed for the simultaneous determination of curcumin, metanil yellow, and sudan dyes in turmeric, chili, and various mixed curry powder formulations....

Determining the adulteration of spices with Sudan I-II-II-IV dyes by UV-visible spectroscopy and multivariate classification techniques.

Talanta 79(3) , 887-92, (2009)

We propose a very simple and fast method for detecting Sudan dyes (I, II, III and IV) in commercial spices, based on characterizing samples through their UV-visible spectra and using multivariate classification techniques to establish classification rules. We...

An ultrasensitive and selective fluorescence assay for Sudan I and III against the influence of Sudan II and IV.

Biosens. Bioelectron. 42 , 136-40, (2013)

We report on an ultrasensitive and selective fluorescence assay for Sudan I and III against the influence of Sudan II and IV based on ligand exchange mechanism. Calcein as a fluorescence indicator and Sudan I-IV as model analytes were employed to investigate ...

Determination of para red, Sudan dyes, canthaxanthin, and astaxanthin in animal feeds using UPLC.

J. Chromatogr. Sci. 48(1) , 22-5, (2010)

A simple high-performance liquid chromatography method was developed for quantitative determination of para red, Sudan I, Sudan II, Sudan III, Sudan IV, canthaxanthin, and astaxanthin in feedstuff. The sample was extracted using acetonitrile and cleaned up on...

Development of enzyme-linked immunosorbent assays for Sudan dyes in chilli powder, ketchup and egg yolk.

Food Addit. Contam. Part A. Chem. Anal. Control. Expo. Risk Assess. 26(6) , 800-7, (2009)

This study aimed at developing sensitive competitive enzyme-linked immunosorbent assays (ELISAs) for the banned Sudan dyes using polyclonal antibodies. Three different formats were developed and characterized in terms of sensitivity, selectivity and rapidity....

[Selection of the optimal method of extraction and determination of dye Sudan I-IV and Para Red by high-performance liquid chromatography].

Vopr. Pitan. 79(2) , 60-5, (2010)

Since 2004 was important the problem of determination of non-food dyes as Sudan I-IV and Para Red. Therefore it was necessary to develop reliable methodologies or adapt existing analytical methods for monitoring the presence of such dyes in food. For this pur...
