E368 – Ammonium fumarate
Acidity RegulatorDescription
White crystalline powder
Notes
Ammonium fumarate is a white crystalline powder made by combining fumaric acid with ammonia compounds. Fumaric acid is found naturally in many plants and fungi, and even plays a role in our body's energy production processes. To create ammonium fumarate, manufacturers react this fumaric acid (which can be sourced naturally or made synthetically) with ammonium compounds, forming what's called an ammonium salt. As an acidity regulator, ammonium fumarate helps maintain the proper acid balance in food products, ensuring they taste right and remain safe to eat. It works by buffering pH levels, preventing foods from becoming too acidic or alkaline. You'll typically encounter this additive in baked goods, processed foods, and beverages where precise acidity control is essential for both flavor and preservation. This additive is suitable for vegetarians and vegans since it doesn't contain any animal-derived ingredients. However, it's worth noting that ammonium fumarate provides a source of nitrogen (from the ammonium), which some food manufacturers actually value as a nutrient supplement in certain products. It's approved by food safety authorities and is generally considered safe for consumption within regulated limits, with no major allergen concerns for most consumers.
