simultaneous determination of eight illegal dyes in chili products by liquid chromatography-tandem mass spectrometry. Cross- contamination or adulteration is one of the main foods contaminating process in the due use of Sudan dyes (Juan Lia et al. 2013).
This experiment ought to have taken pre-cautions to inform its readers on the harmful effects of these eight illegal dyes in chili products. Spectrophotometric method could have been discussed somewhere in this paper as a way that can be used to detect the presence of Sudan dyes and other illegal dyes in chili powders or any other food stuff in ppm levels (Juan Lia et al. 2013). This method has been found reliable in identifying and estimating the level of sudan I-IV in Chili samples. Ethyl acetate is yet another useful solvent used to extract dyes from chili samples as well as the preparation of samples. The eight illegal dyes discussed in this paper cause carcinogenicity which is a high producing capacity among many other ailments.
Otherwise, the paper developed the HPLC-MS/MS chronologically from the first to the last step demonstrating the extraction procedure used to determine eight illegal synthetic dyes in chili products simultaneously. The selection of MS/MS technique combined with chromatographic separation was an accurate method of determining compounds in complex matrices with less ambiguity (Juan Lia et al. 2013). The method was effective that it did not require the laborious clean up procedures. The method was highly accurate with a good repeatability. The detection of any limits like quantification limits was minimal (Juan Lia et al. 2013). The HPLC-MS/MS process employed in the paper proved to be effective for fraud detections in both exported and imported chili products.
The analysis of data was done effectively through the use of graphs and tables to illustrate the results.
