Chocolate Brown HT
Brown HT is a bis azo-dye food coloring consisting of reddish-brown powder or granules. The color provides a blackish brown shade in applications that is like cocoa or caramel.
Typical applications include confectionery, bakery, dairy fats and oil, meat, seafood, snacks, dry mixes and seasonings, fruit preparation, convenient food, and flavors.
The Codex Alimentarius Commission has finalized authorization of Brown HT for use in flavored fluid milk drinks (food category number 1.1.4) with a maximum proposed level (MPL) of 150 mg/kg, as noted in the General Standard of Food Additives. Many other applications of Brown HT as a color additive in foods and beverages have been proposed and are pending authorization, following completion of the review and comments process.
JECFA reviewed Brown HT at its 28th meeting, where it considered the results of multigeneration reproduction, teratological, and metabolic studies, as well as a special study on pigment deposition in the kidney and mesenteric lympth nodes. An ADI of 0-1.5 mg/kg of body weight was established, on the basis of a no-effect level of 0.1%, equivalent to 150 mg/kg of body weight, in the long-term feeding study in mice.
