Other names for the additive (synonyms)
General Information
Sodium sulfates (food additive E514) are mineral compounds used in the food industry as acidity regulators, carriers, and sometimes as stabilizers. They belong to the group of salts and help maintain the technological properties of products.
Sodium sulfate can occur naturally as minerals, such as Glauber's salt, formed in salt lakes and natural deposits. For the food industry, it is often produced industrially from natural raw materials or as a by-product of other processes.
The history of this substance dates back to the 17th century, when the German chemist Johann Glauber described a mineral later called Glauber's salt. Initially, it was used in medicine, and with the development of the chemical industry, it was applied in glass, detergents, and food production. Over time, sodium sulfate gained the status of food additive E514.
The chemical formula of sodium sulfate is Na2SO4. It is a colorless or white crystalline substance without odor, highly soluble in water. The substance has a neutral or slightly salty taste. It is chemically stable, non-flammable, and does not exhibit significant reactivity under normal conditions.
For food use, sodium sulfate is obtained by purifying natural mineral raw materials or synthesized from available sodium salts and sulfuric acid. The product is then purified, crystallized, and quality-controlled to meet safety standards.
Effects on the Body
Benefits of Additive E514
Food additive E514 is not a nutrient and has no proven biological benefits for the human body. It does not participate in metabolic processes like a vitamin or trace element. Its primary function is technological.
According to the scientific assessment by the European Food Safety Authority (EFSA), sodium sulfate has low toxicity when consumed orally and is rapidly excreted from the body. EFSA considered sodium, potassium, and calcium sulfates together and noted that establishing a numerical ADI is not necessary, as consumption levels do not pose a risk.
In small amounts, sodium sulfate is hardly absorbed and is excreted naturally.
Risks of Additive E514
After ingestion, sodium sulfate is partially absorbed in the intestine, and excess retains water in the intestinal lumen and may be excreted with feces. Due to this property, high doses of sulfates are known for their laxative effect.
EFSA notes that at normal consumption levels, additive E514 does not raise safety concerns. Very high doses, however, may cause diarrhea and gastrointestinal discomfort.
JECFA also evaluated sodium sulfates and concluded that at normal dietary use, they do not pose a significant health risk, and establishing a specific ADI is not necessary.
In the USA, the FDA classifies sodium sulfate as a substance permitted in foods under good manufacturing practice. Exceeding reasonable amounts may result in a laxative effect, which is the primary potential risk.
Uses
In the food industry, additive E514 is used as an acidity regulator and carrier for other additives. It helps stabilize product composition and maintain the required mineral balance.
Additive E514 can be found in some beverages, jelly and dessert products, instant foods, specialized food mixes, and technological additives for food processing.
Its use involves small doses that do not affect taste but ensure recipe stability.
Legal Status
In the European Union, food additive E514 is allowed according to Regulation (EU) No 1333/2008. EFSA in 2019 confirmed that establishing a numerical ADI is unnecessary due to the low-risk level.
In Ukraine, additive E514 is allowed in quantities harmonized with EU legislation.
In the USA, sodium sulfate is permitted by the FDA for food use under good manufacturing practice. In Canada and Japan, it is also allowed as a food additive when purity standards are met.
Therefore, food additive E514 is permitted in most countries and considered safe when used in technologically justified amounts.
