4-Methylimidazole
4-Methylimidazole, often abbreviated as 4-MEI, is a heterocyclic organic chemical compound with the molecular formula. It is formally derived from imidazole by replacing hydrogen in position 4 with a methyl group. This is a slightly yellowish solid with a density of 1.02 g/cm3, melting point 46-48 ° C, the boiling point of 263 ° C and flash point 157 ° C.
4-Methylimidazole can be formed in the maturity of certain types of food through the Maillard reaction between carbohydrates and amino-containing compounds. In particular, it was found in baked goods; grilled meats, coffee, and caramel coloring types are produced with ammonia
preparation.
4-Methylimidazole can be made using a whistle-Radziszewski synthesis of imidazole, the reaction of methylglyoxal with ammonia and formaldehyde. It can also be prepared by reacting to the hydroxyacetone and formamide in the ammonia. Based process. It also may arise by fermentation.
Putting Risk in Perspective: Here's what you need to know. . .
At a particular beverage, most people would consider the meaning of caramel-colored with caramel coloring, but some materials have much in common with ordinary caramel or caramel candy. This is a solid dark-brown mixture of chemicals that do not occur in nature. Caramel is plain unhealthy, but at least it is not contaminated by carcinogens. "
Presence of trace levels of naturally-occurring compounds in foods does not make food unsafe. Choose foods rich in a variety of whole grains, fruits, and vegetables that reduce the exposure to 4-MEI and maximize the overall restructuring.
