Codex Provisions

The Codex Alimentarius Commission has finalized authorization of Azorubine (Carmoisine) use in soups and broths (food category number 12.5) with a maximum proposed level (MPL) of 50 mg/kg and flavored fluid milk drinks (food category number 1.1.4) with a MPL of 150 mg/kg, as noted in the General Standard of Food Additives. Many other applications of Azorubine (Carmoisine) as a color additive in foods and beverages have been proposed and are pending authorization, following completion of the review and comments process. Most applications are at Step 7 of the Step Process with few at Step 4 of the Process. The MPL for most of these applications range from 200-500 ppm, with few exceptions of lower limits in selected types of foods.

Regulatory Approvals

EU: ADI of 0-4 mg/kg body weight (EFSA, 2009). EFSA has also established Maximum Permitted Levels of use of Azorubine/Carmoisine in beverages and food stuffs according to Council Directive 94/36/EC.

JECFA: ADI of 0-4 mg/kg body weight (27th report, 1983)
