Food additives Europe numbers: E517
Ammonium sulfate is not a common food additive and its use is generally discouraged due to several factors. Here's a breakdown:
- No Approved Use in Food: Unlike some other ammonium compounds used historically in baking (like ammonium bicarbonate), ammonium sulfate is not approved for use as a food additive by regulatory bodies like the FDA [1].
- Unpleasant Taste and Potential Health Concerns: Similar to ammonium chloride, it has a bitter and unpleasant taste that would be undesirable in most food products [2]. Additionally, while the effects of low-level ingestion might be minimal, high consumption of ammonium sulfate can be harmful [3].
- Alternatives Exist: There are safer and more suitable alternatives available for any potential functions ammonium sulfate might propose in food science:
- Acidity Regulation: Depending on the food product, options like citric acid, lactic acid, or other food-grade acids are commonly used [4].
- Flavor Enhancement: Salt (sodium chloride) or other flavoring agents like potassium chloride can be used for a salty taste, while various herbs, spices, or extracts can enhance other flavor profiles [5].
Limited Information on Historical Use:
There's very little documented evidence suggesting any widespread historical use of ammonium sulfate as a food additive. Some sources might mention it in passing, but its safety and effectiveness for food applications haven't been established.
Overall:
Ammonium sulfate is not a recommended or approved food additive. Its unpleasant taste and potential health concerns make it unsuitable for human consumption. Safer and more effective alternatives exist for acidity regulation and flavor enhancement in food science.
