E180 - Litholrubine bk

Origin

Litholrubine BK (E180) is a synthetic azo dye. It is produced by diazotization of 4-aminotoluene-3-sulfonic acid and coupling with 3-hydroxy-2-naphthoic acid. It is an artificial colorant, meaning it does not occur naturally and is manufactured through chemical processes.

Usage

Litholrubine BK is used as a food coloring agent, providing a red to bluish-red hue. Its primary application is in coloring food products such as sausage casings, certain confectionery items, and some snack foods. The dye is valued for its stability and color intensity. However, its use is limited due to regulatory restrictions in several countries. It is also used in some cosmetic products.

Side Effects

While Litholrubine BK is approved for use in some regions, concerns have been raised regarding potential adverse effects. Some studies suggest that azo dyes, including Litholrubine BK, may trigger allergic reactions in sensitive individuals. These reactions can manifest as skin rashes, itching, or respiratory problems. There is also some debate regarding the potential link between azo dyes and hyperactivity in children, although the evidence is not conclusive. The Scientific Committee for Food (SCF) established a temporary ADI (Acceptable Daily Intake) of 0-1.5 mg/kg body weight, but this was later withdrawn due to data gaps. Further research is needed to fully assess the safety profile of Litholrubine BK.

Regulatory Status

The use of Litholrubine BK is regulated in many countries. Its approval status varies significantly. For example, it is permitted in the European Union for specific applications, such as sausage casings, under strict conditions. However, it is not approved for use as a food additive in the United States. Regulatory bodies like the European Food Safety Authority (EFSA) and the Food and Drug Administration (FDA) continuously review the safety data of food additives to ensure consumer safety. The absence of an ADI reflects the need for more comprehensive toxicological data.
