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 carbonates soluble?
It depends on the cation: the alkali carbonates used as E502 in foods are readily water‑soluble, while alkaline‑earth carbonates (like calcium or magnesium carbonate) are only sparingly soluble.
What carbonates soda?
Carbon dioxide gas dissolving under pressure is what carbonates soda; E502 carbonates aren’t typically used to carbonate beverages except when reacted with an acid to release CO2.
Do bases react with carbonates?
Not in a typical neutralization sense—both are alkaline; strong bases can shift bicarbonate/carbonate equilibria (e.g., convert HCO3− to CO3^2−) without releasing CO2.
What carbonates water?
Carbon dioxide carbonates water naturally (from geological sources) or by injection; E502 carbonates generate CO2 only when acidified, as in leavening systems, not on their own.
Do acids react with carbonates?
Yes—acids react with carbonates to form a salt, water, and carbon dioxide gas, which is how E502-type leavening agents release CO2 in doughs and batters.
