E510 - Ammonium chloride

Origin

Ammonium chloride is an inorganic compound with the formula NH₄Cl. It is a white crystalline salt that is highly soluble in water. It occurs naturally as the mineral sal ammoniac, typically formed on burning coal dumps from condensation of coal-derived gases. Commercially, it is produced by reacting ammonia with hydrochloric acid or as a byproduct of the Solvay process for producing sodium carbonate.

Usage

In the food industry, ammonium chloride is used as a flavor enhancer, dough strengthener, and acidity regulator. It is often found in licorice candy to provide a salty-licorice flavor. It is also used in baking to improve the texture of baked goods. In addition to food applications, ammonium chloride has various industrial uses, including in fertilizers, dry cell batteries, and as a flux in soldering. It is also used in medicine as an expectorant and diuretic.

Side Effects

Ammonium chloride is generally recognized as safe (GRAS) when used in accordance with good manufacturing practices. However, excessive consumption can lead to metabolic acidosis, particularly in individuals with kidney or liver problems. Symptoms of excessive intake may include nausea, vomiting, and headache. The EFSA (European Food Safety Authority) has not established a specific ADI (Acceptable Daily Intake) for ammonium chloride as a food additive, but its use is regulated within specific limits in certain food categories. Individuals with pre-existing medical conditions should consult with a healthcare professional before consuming large amounts of products containing ammonium chloride.

Regulatory Status

Ammonium chloride (E510) is permitted for use as a food additive in the European Union, subject to certain conditions and restrictions outlined in Annex II of Regulation (EC) No 1333/2008. In the United States, it is generally recognized as safe (GRAS) by the Food and Drug Administration (FDA) when used in accordance with good manufacturing practice.
