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.
What is sodium thiosulfate used for?
As a food additive (E539), it functions as an antioxidant and sequestrant, binding trace metals and helping prevent oxidation; it’s also used to neutralize residual chlorine in processing water.
How much sodium thiosulfate to neutralize chlorine?
About 7 parts of sodium thiosulfate pentahydrate (Na2S2O3·5H2O) are needed per 1 part of chlorine (as Cl2) by weight—for example, ~7 mg/L thiosulfate per 1 mg/L free chlorine; in practice, a small excess is often used.
Is gold sodium thiosulfate in makeup?
Gold sodium thiosulfate is a different compound from food additive E539 and isn’t typically used in cosmetics; check the ingredient list if you’re concerned about gold-containing ingredients.
How many elements are in sodium thiosulfate?
Anhydrous sodium thiosulfate (Na2S2O3) contains 3 elements (Na, S, O); the common pentahydrate (Na2S2O3·5H2O) includes 4 (adds H from the water of crystallization).
What does sodium thiosulfate do?
In foods it acts as an antioxidant and sequestrant, helping prevent oxidation and off-colors by binding metals, and it can dechlorinate processing water.
