Popular questions
Is citric acid bad for you?
At typical food levels, citric acid (E330) is considered safe by major regulators (GRAS; EFSA/JECFA). Concentrated or frequent acidic exposure can irritate the mouth/stomach or contribute to tooth enamel erosion.
Where does the citric acid cycle occur?
In eukaryotic cells it occurs in the mitochondrial matrix; in bacteria it occurs in the cytosol.
What does citric acid do to your body?
It is a normal intermediate in energy metabolism and is readily metabolized to carbon dioxide and water. Citrate can bind minerals, which may enhance absorption of some and help prevent certain kidney stones by increasing urinary citrate.
Where does citric acid come from?
It occurs naturally in citrus fruits, but most food-grade citric acid is produced by fermenting sugars (e.g., from corn, beet, or cane) with Aspergillus niger.
How is citric acid made?
Industrially, sugars are fermented with Aspergillus niger to produce citric acid, then it is recovered and purified—often by precipitating calcium citrate and converting it back with sulfuric acid or via ion-exchange/crystallization.
Is disodium phosphate bad for you?
Generally no—E339(ii) is an approved additive used at low levels; however, it contributes sodium and phosphate, so people with kidney disease or on phosphate‑restricted diets should limit it.
What is disodium phosphate in food?
It's the sodium salt Na2HPO4 (E339(ii)) used as an emulsifier, acidity regulator/buffer, stabilizer, sequestrant, humectant, and thickener.
What is disodium phosphate used for?
It emulsifies processed cheese, controls acidity, improves texture and moisture retention in dairy and meat products, and binds metal ions that can affect flavor and color.
Is disodium phosphate safe?
Yes—it's permitted by regulators (e.g., FDA GRAS; EU E339) and considered safe at typical food levels, though very high phosphate intakes are discouraged, especially for people with kidney problems.
What does disodium phosphate do?
It keeps mixtures smooth and stable, maintains pH, binds minerals to protect quality, and can help foods retain moisture and thickness.
