Ammonium malate

Ammonium malate is a chemical compound that is a salt of ammonium and malic acid. It is often used in the food industry as a flavor enhancer and acidity regulator.

Chemical Structure

Ammonium malate is composed of one ammonium ion (NH4+) and one malate ion (C4H4O5-). The malate ion is derived from malic acid, a dicarboxylic acid that is found in various fruits and vegetables, most notably apples. The ammonium ion is derived from ammonia (NH3), a compound of nitrogen and hydrogen.

Properties

Ammonium malate is a white, crystalline powder. It is soluble in water and has a slightly acidic taste. It is stable under normal temperatures and pressures, but it can decompose if heated.

Uses

In the food industry, ammonium malate is used as a flavor enhancer and acidity regulator. It can enhance the natural flavors of foods and provide a sour taste. It is also used in the production of some types of cheese, where it helps to control the acidity of the cheese and promote the growth of beneficial bacteria.

In addition to its use in food, ammonium malate is also used in the pharmaceutical industry. It can be used as a buffer in pharmaceutical formulations, helping to maintain the pH of the product.

Safety

Ammonium malate is generally recognized as safe (GRAS) by the FDA. However, like all food additives, it should be used in moderation. Excessive consumption of ammonium malate can lead to gastrointestinal discomfort, including nausea and diarrhea.
