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.
Are tocopherols bad for you?
No—tocopherols (E306, natural vitamin E) are considered safe at permitted food-use levels; issues mainly arise with excessive supplement doses, which can increase bleeding risk or cause mild stomach upset.
Are tocopherols safe for dogs?
Yes—mixed tocopherols are commonly used as natural preservatives in dog foods and are considered safe at those levels; avoid high-dose vitamin E supplements for pets unless advised by a veterinarian.
What are tocopherols in food?
They are vitamin E compounds (E306) extracted from vegetable oils, added as antioxidants to slow oxidation and rancidity, especially in fatty foods.
What is tocopherols in food?
In foods, “tocopherols” (E306) refers to a vitamin E–rich extract used as an antioxidant to stabilize oils and preserve flavor.
Are tocopherols safe?
Yes—E306 is generally considered safe at normal food levels (authorized in the EU and GRAS in the U.S.); risks mainly come from very high supplemental intakes.
