Monitoring for illegal and artificial dyes in your favorite foods
The food color additives that are commonly found in many of the foods we eat are used for a variety of reasons, like enhancing color and making products more fun and appetizing.
While many color additives are generally ‘recognized as safe’ or GRAS, studies have identified possible links between the consumption of foods containing dyes to increased hyperactivity in children. While some dyes, such as azo-dyes, are banned as food additives and are highly regulated, others are simply chemicals of concern, and should be continually monitored.
Analyzing dyes in foods is particularly difficult because these food samples are inherently complex, and analysis of low-levels of dye compounds is challenging. Mass spectrometry is an excellent solution for this analysis, as the sensitivity of the instrument enables added sample dilution to remove matrix interferences, and the workflow lends itself to the analysis of many dyes in a single run, resulting is highly reliable determination of how much of targeted chemical dyes are present in food samples.
