Ammonium Phosphates (E342)
Type of additive (Glossary) | Acidity Regulators Leavening Agents Stabilizers Thickeners |
E Number | E342 |
Chemical Formula | (NH4)3PO4 |
Also Known As | Monoammonium phosphate (i) Diammonium phosphate (ii) |

Purpose and Function
Ammonium Phosphates (E342) are used in the food industry as acidity regulators, stabilizers, leavening agents, and nutrient sources. They help control pH, improve texture, and provide a source of nitrogen and phosphorus, especially in yeast-based products. Common applications include:
- Baked goods: Used as a leavening agent in baking powders to help the dough rise.
- Nutritional supplements: Sometimes included as a source of nitrogen and phosphorus in dietary supplements.
- Brewing: Provides a source of nitrogen for yeast growth in brewing and fermentation processes.
- Confectionery: Helps control acidity and improve the texture of sweets and candies.
- Dairy products: Stabilizes and thickens products such as cream, yogurt, and some cheeses.
Ammonium Phosphates (E342) offer functional benefits in food processing, especially in baking and fermentation.
Potential Risks and Side Effects
Ammonium Phosphates (E342) are generally considered safe when used within regulated limits, but there are some considerations:
- Excessive ammonia intake: High amounts may lead to elevated ammonia levels in the body, which could cause digestive discomfort or more serious health effects, particularly for individuals with compromised liver function.
- Phosphate overload: Excessive phosphate intake from processed foods can affect bone health and kidney function.
- Regulatory approval: Ammonium Phosphates (E342) are approved for use in many countries, including the European Union, where they are considered safe within specified limits.
Overall, Ammonium Phosphates (E342) are regarded as safe food additives when used appropriately, with monitoring for specific health conditions.
