E571 – Ammonium stearate
Anticaking agentDescription
Mixture of ammonium salts of stearic and palmitic acids; white to yellowish-white powder or flakes
Notes
Ammonium stearate is created by combining ammonia with stearic acid and palmitic acid – two fatty acids that are commonly found in animal fats and plant oils like palm oil and cocoa butter. The manufacturing process involves neutralizing these fatty acids with ammonia, creating ammonium salts that form a fine, waxy powder. Think of it as similar to making soap, but using ammonia instead of the sodium hydroxide typically used in soap-making. This additive works as an anticaking agent, preventing powdered foods from clumping together by creating a thin, lubricating layer around individual particles. You'll most commonly find it in cocoa powder, powdered chocolate drinks, some baking mixes, and other chocolate-containing powdered products. It's particularly useful in chocolate processing because it helps maintain the smooth, free-flowing texture that's important for both manufacturing and consumer use. Ammonium stearate can be derived from either animal or plant sources, depending on where the stearic and palmitic acids come from, so vegetarians and vegans should check with manufacturers if this is a concern. When derived from animal fats, it would not be suitable for halal or kosher diets either. The compound is considered safe for consumption in the small amounts used as an anticaking agent, and both the ammonia and fatty acid components are substances that the body can process naturally.
