Horizon Technology, Inc. has just released its application notes for the analysis of 4-methylimidzaole using automated solid phase extraction and high performance liquid chromatography with MS/MS and MS/SIM detection. Babcock Laboratories played an important role in the development of these notes by offering support and the use of our methods, systems, and standards. We are very proud of our Organics Manager, David Schiessel, and our Laboratory Director of Operations, Paul Monroy, for their excellent work on this joint project with Horizon Technology.
Background on 4-MEI: “The compound 4-methylimidazole (4-MEI) is formed as a byproduct in some foods and beverages. Caramel coloring Type III and Type IV in beverages is one of the ingredients which may contain 4-MEI. Products that potentially contain 4-MEI include certain colas, beers, soy sauces, breads, coffee, ammoniated livestock feed and other products. There has been an increase in concern lately about 4-MEI being a suspected carcinogen. Europe has regulated the amount of 4-MEI allowed in coloring used in food products. The state of California has added 4-MEI to its proposition 65 list of known carcinogens. California now requires products with an exposure potential of >29 μg/day to carry warning labels. The trend shows potential expansion as this compound is receiving a lot of public attention and is the subject of ongoing studies.”
