Is Ammonia Caramel (E150c) Vegan?

Also known as: Class III caramel, Caramel color III, Beer caramel, Baker's caramel

Vegan

Ammonia caramel is vegan. Manufacturers heat plant sugars with ammonium compounds to make a dark, heat-stable color, and no step involves animal material. The ammonia comes from industrial synthesis, not from any animal source.

Vegan Status

Vegan

E-Number

E150c

Also Known As

Class III caramel; Caramel color III; Beer caramel; Baker's caramel

Source

Made by heating plant carbohydrates in the presence of ammonium compounds. The sugar feedstock is glucose syrup, sucrose, invert sugar, or molasses, usually from corn, wheat, or cane. Ammonium hydroxide, carbonate, or phosphate is added to push the browning reaction further and give a deeper, more heat-stable color.

Commonly Found In

Beer and dark ales, soy sauce, gravy browning, malt vinegar, bakery goods, pet food, sauces, confectionery.

Vegan Alternative

No substitute needed. E150c is vegan.

Additional Notes

E150c is the caramel class used where the color has to survive baking, fermentation, or a salty environment. Cooking with ammonium compounds produces two byproducts regulators track: 4-methylimidazole and 2-acetyl-4-tetrahydroxybutylimidazole. EFSA set a group acceptable daily intake for all four caramel classes in 2011 and a tighter individual limit for E150c.

In depth

Why Brewers and Soy Sauce Makers Use It

Class III caramel carries a positive charge in solution, which keeps it stable in beer, soy sauce, and other protein-rich or salty liquids where other caramel classes would flocculate and drop out. Dark beers, brown sauces, and gravy brownings all rely on that behavior. The color it delivers is deeper and redder than plain caramel. It also survives baking.

Bakers use it in rye and pumpernickel-style breads and in malt loaves. Soy sauce is the case that trips readers up most often, since the sauce itself contains no animal ingredients but sits beside fish sauce on the shelf. Ammonia caramel in soy sauce is a plant-derived color, and the sauce is vegan unless it names bonito, anchovy, or another animal extract.

Where the Ammonia Comes From

Ammonium hydroxide and ammonium salts used in caramel manufacture are made from ammonia, and industrial ammonia is produced by the Haber-Bosch process: nitrogen pulled from the air, hydrogen from natural gas, combined under pressure over an iron catalyst. Historical ammonia sources included distilled animal horn and collected urine. That is where the old name "spirits of hartshorn" came from. Those routes disappeared from industry more than a century ago. No commercial caramel producer sources ammonia from an animal today. Where a label lists E150c, the color is plant carbohydrate browned with a synthetic nitrogen compound. It needs no further checking for animal content.

The Safety Questions That Do Exist

Cooking sugar with ammonium compounds generates 4-methylimidazole, known as 4-MEI, and 2-acetyl-4-tetrahydroxybutylimidazole, known as THI. Both are byproducts, not added ingredients, and EU specifications cap how much of each a batch may contain. EFSA re-evaluated all four caramel classes in 2011 and set a group acceptable daily intake of 300 mg per kilogram of body weight per day, with a lower individual figure of 100 mg for E150c because of THI's effects on white blood cell counts in animal studies.

California added 4-MEI to its Proposition 65 list in 2011, which pushed several soft drink makers to reformulate. None of this bears on the vegan question. The evidence base rests on animal testing, as most additive toxicology does, and anyone who objects to that on principle would need to apply the same objection across nearly the whole additive list.

Frequently asked questions

Is E150c vegan?

Yes. Ammonia caramel is made from plant carbohydrate heated with ammonium compounds, and the ammonia used is produced industrially from atmospheric nitrogen. No animal-derived material takes part.

Does ammonia caramel contain actual ammonia?

No meaningful residue remains. Ammonium compounds drive the browning reaction and are consumed or removed during manufacture, leaving a color with a specified maximum for nitrogen-containing byproducts. Finished caramel color has no ammonia smell or taste.

Is soy sauce with caramel color vegan?

Yes, in almost every case. Soy sauce is made from soybeans, wheat, salt, and a fermentation culture, and E150c is a plant-derived color. Check for named animal extracts such as bonito or anchovy in fusion sauces and dipping blends.

Which caramel class is used in cola?

Cola drinks use E150d, sulfite ammonia caramel, which is stable in acidic carbonated liquid. E150c is the class used in beer, soy sauce, and baked goods. Both are vegan.
