Importance of Sudan Red Determination
Sudan dyes are inexpensive fat-soluble azo compounds, used mainly as colorants in the manufacturing of oils, wax products, lacquers and inks since their bright and vivant colors can improve the luster of commercial products. Sudan I is classified as a carcinogen by the International Agency for Research in Cancer (IARC). Sudan II, the dimethyl derivative of Sudan I has been shown to cause bladder carcinomas in mice at a high frequency. Due to their potential carcinogenicity, many countries have banned the use of Sudan dyes (I - IV) in products for human consumption. Similar to Sudan I, Para
Red has also been shown to be carcinogen.

Sudan dyes are often used illegally to enhance and/or maintain the appearance of food products, such bell peppers, curry, chili powders, etc. Contamination of meat products has also occurred. Therefore, control of Sudan Red dyes in food products is crucial to insure food safety.

General description
The Sudan Red ELISA is an immunoassay for the quantitative and sensitive screening of Sudan Red and analogs. This test is suitable for the quantitative and/or qualitative screening of Sudan Red in food samples such as tomato juice, tomato sauce, chili sauce, chili powder, etc. (please refer to the appropriate technical bulletins for extraction/dilution procedures). Samples requiring regulatory action should be confirmed by HPLC, GC/MS, or other conventional methods.

The Sudan Red ELISA allows the determination of 42 samples in duplicate determination. The test can be performed in approximately 1 hour
