E153 - Vegetable carbon

Origin

Vegetable carbon, also known as vegetable black or activated vegetable carbon, is a black pigment produced by the incomplete combustion of vegetable matter, such as wood, peat, coconut shells, or other plant residues. The raw materials are charred at high temperatures in the absence of oxygen, a process called pyrolysis. The resulting carbonaceous material is then further processed to achieve the desired particle size and purity for use as a food colorant.

Usage

E153 is used as a black food coloring agent. It imparts a black or dark grey color to a variety of food products. Common applications include confectionery (e.g., licorice, jelly beans), bakery products (e.g., dark breads, cakes), dairy products (e.g., black ice cream), and beverages. It is also used in the coloring of capsules and tablets in the pharmaceutical industry. The coloring effect is achieved by the dispersion of the fine carbon particles within the food matrix. It is also used in some cosmetics.

Side Effects

Vegetable carbon is generally considered safe for consumption. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has established an Acceptable Daily Intake (ADI) of 'not specified', meaning that, based on available data, the intake of vegetable carbon at levels necessary to achieve the desired technological effect in food does not pose a health risk. However, some individuals may experience gastrointestinal discomfort, such as bloating or constipation, if consumed in large quantities. As with any food additive, allergic reactions are possible, although rare. Regulatory bodies like EFSA and FDA have reviewed the safety of vegetable carbon and permit its use within specified limits.

Regulatory Status

E153 is approved for use as a food additive in many countries, including the European Union, the United States, and Canada. In the EU, it is subject to specific purity criteria and labeling requirements as outlined in Commission Regulation (EU) No 231/2012. In the US, it is regulated by the FDA under 21 CFR Part 73.260, where it is listed as a color additive exempt from certification. The use levels are typically dictated by Good Manufacturing Practices (GMP) and should not exceed the amount necessary to achieve the intended coloring effect.
