A review of analytical techniques for determination of Sudan I-IV dyes in food matrixes.
TLDR
This paper critically reviews the published determination methods of Sudan I-IV dyes and suggests that UV-vis absorbance detection is applied more and more often as it offers more reliable identification possibilities.About:

Methods for the analysis of azo dyes employed in food industry--A review.
TL;DR: A comprehensive review of various analytical techniques used in the analysis of azo dyes employed in food industries of different parts of the world is presented.
Journal ArticleDOI
Food colors: Existing and emerging food safety concerns
TL;DR: The most important food safety concerns in the field of food colors are lack of uniform regulation concerning legal food colors worldwide, possible link of artificial colors to hyperactive behavior, replacement of synthetic colors with natural ones, and the presence of harmful illegal dyes—both known but also new, emerging ones in food.
Journal ArticleDOI
Applications of liquid chromatography-mass spectrometry for food analysis.
Vita Di Stefano,Giuseppe Avellone,David Bongiorno,Vincenzo Cunsolo,Vera Muccilli,Stefano Sforza,Arnaldo Dossena,László Drahos,Károly Vékey +8 more
TL;DR: The characterization of food quality (including problems of authentication and adulteration) is discussed, together with a future outlook on future directions.
Journal ArticleDOI
Critical review on hazardous pollutants in water environment: Occurrence, monitoring, fate, removal technologies and risk assessment.
TL;DR: In this article, the occurrences and fate of hazardous contaminants (dyes, pharmaceuticals and personal care products, heavy metals, fertilizer and pesticides) found in wastewater effluents are reviewed.
Journal ArticleDOI
Binding of Sudan II and Sudan IV to bovine serum albumin: comparison studies.
TL;DR: Structural analysis showed that both Sudan II and Sudan IV interact mainly with BSA at the hydrophobic pocket and via Van der Waals forces, suggesting a partial protein unfolding.

On the Mechanism of the cis−trans Isomerization in the Lowest Electronic States of Azobenzene: S0, S1, and T1
TL;DR: The results indicate that the S(1) state decay involves mainly the torsion route and that the inversion mechanism may play a role only if the molecule is excited with an excess energy of at least 25 kcal/mol with respect to the S (1) minimum of the E isomer.

TL;DR: Cathepsin B, and potentially other proteases, may serve as a biomarker for vulnerable plaques when probed with beacons and the tomographic in vivo imaging method could be readily adapted to screening and potentially to the molecular profiling of a number of proteases in vulnerable plaque in vivo.
Journal ArticleDOI
Simultaneous determination of water-soluble and fat-soluble synthetic colorants in foodstuff by high-performance liquid chromatography-diode array detection-electrospray mass spectrometry.
TL;DR: An accurate method was developed for the simultaneous determination of water-Tartrazine, Amaranth, Ponceau 4R, Sunset Yellow FCF, and fat-Sudan (I-IV), synthetic soluble colorants in foodstuff.
Journal ArticleDOI
Sequence and structural features of carbohydrate binding in proteins and assessment of predictability using a neural network.
Adeel Malik,Shandar Ahmad +1 more
TL;DR: Statistics of amino acid compositions in binding versus non-binding regions- general as well as in each different secondary structure conformation are compiled and neural networks give a moderate success of prediction, which is expected to improve when structures of more protein-carbohydrate complexes become available in future.

A rapid HPLC method for determination of Sudan dyes and Para Red in red chilli pepper
TL;DR: In this paper, a rapid high-performance liquid chromatography (HPLC) system consisting of an ultraviolet-visible (UV-VIS) detector was developed for the separation and determination of Sudan dyes (I, II, III, and IV) and Para Red in red chilli peppers.
