Allura Red AC
Food Colourant
Allura Red AC is a food colorant that functions as a deep red, water-soluble compound. It is widely utilized in a variety of applications including beverages, syrups, candies, and cereals. Notably, Allura Red AC can statically quench the intrinsic fluorescence of human serum albumin (HSA) and serves as a pro-inflammatory agent linked to the 5-hydroxytryptamine (5-HT) pathway, which may exacerbate conditions like experimental colitis. This compound is valuable for research focusing on inflammatory bowel disease, intestinal barrier function, and the safety of food additives.
