Illegal Dye Testing
Since the illegal dyes scare began in early 2004 QTS has been at the forefront of the testing of a wide range of commodities for these contaminants. Working closely with Leatherhead Food International, QTS has provided a vast amount of testing in what are often very complex samples such as oleoresins.
We have been able to develop a large screen for such dyes with routine reporting limits of 100ppb. In most instances these reporting limits are significantly above the limit of detection, for some of the dyes we are easily able to detect 5ppb.
As with our pesticide testing we are also able to provide a rapid response to our customer needs. We currently offer standard 5 day turnarounds as well as being able to offer a rapid turnaround that provides results within 24 hours for real emergencies.
The illegal dyes covered in our screen are as follows:
Sudan I
Sudan II
Sudan III
Sudan IV
Para Red
Orange II
Sudan Black B
Sudan Red G
Sudan Red 7B
Sudan Red B
Rhodamine B
Butter Yellow
Sudan Orange G
Toluidine Red
QTS is currently participating in the FSA study on these dyes in food products and also participates in the CSL organised proficiency testing scheme FAPAS.
If you have any questions regarding this testing or would like a quote, please do not hesitate to contact us.
