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.

The compound 4 Methylimidazole (4-MeI) is made during the production of caramel color commonly found in foods and beverages, especially sodas.
The Codex Alimentarius of the World Health Organization sets a limit of 250 mg/kg of 4-MeI. Also, the state of California has added 4-MeI to its Prop 65 list at an exposure level of 29 μg/day.
This study looks at 4-MeI levels in sodas and malt sodas which
are sold in and outside the state of California. The first section, included in this poster, describes the performance of automated solid
phase extraction of 4-MeI using conventional HPLC/MS detection.
