Overview

E264 - Ammonium acetate

Ammonium acetate (E264) is a simple salt made from ammonia and vinegar’s main acid. Food makers use it in small amounts to control acidity and help keep some foods shelf-stable. It appears on labels as “ammonium acetate” or “E264.”

E527 - Ammonium hydroxide

Ammonium hydroxide (E527) is a water solution of ammonia used in tiny amounts to control acidity and help keep some foods safe during processing. It can also take part in making certain caramel colors and is tightly regulated in both the U.S. and EU.

Popular questions

How to prepare ammonium acetate buffer solution?
Dissolve ammonium acetate in water to the desired concentration (e.g., 1 M: about 77 g per liter), then adjust pH to your target with acetic acid (to lower) or ammonia (to raise) and dilute to volume. Use food-/pharma-grade materials and verify pH after mixing.
Is ammonium acetate soluble in water?
Yes—it's highly soluble in water.
Ammonium acetate dissolves into what ions?
It dissociates into ammonium (NH4+) and acetate (CH3COO−) ions.
Ammonium acetate in what products contain?
It may appear in some pickled products, sauces, and baked goods as an acidity regulator/buffer (E264). It’s relatively uncommon and is often replaced by sodium or potassium acetates.
Consider the reaction when aqueous solutions of ammonium acetate and sodium phosphate are combined.?
All ions remain in solution (no precipitate), leaving NH4+, CH3COO−, Na+, and phosphate species in equilibrium. In a sufficiently basic phosphate solution, some NH4+ can convert to ammonia, making the mixture slightly basic and possibly giving a mild ammonia odor.
