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 calcium disodium edta?
Calcium disodium EDTA (E385) is a synthetic chelating agent—closely related to disodium EDTA (E386)—that binds trace metals in foods to help prevent off-flavors, discoloration, and oxidation.
Is calcium disodium edta harmful?
Not at permitted food-use levels; regulators set an acceptable daily intake of roughly 1.9–2.5 mg/kg body weight/day, and typical intakes are well below this. Very high doses can chelate essential minerals and may cause stomach upset.
Is disodium edta safe for skin?
Yes—disodium EDTA is widely used in cosmetics at low levels and is considered safe, with a low risk of irritation for most people.
Is calcium disodium edta bad for you?
No—when used within legal limits in foods, it’s considered safe; concerns mainly arise only at excessive exposures that could deplete minerals.
Is disodium edta safe?
Yes—within approved uses and limits, disodium EDTA is considered safe; EDTA salts have an ADI of about 1.9–2.5 mg/kg body weight/day set by major regulators.
