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 h2so4 a strong acid?
Yes—sulfuric acid (H2SO4) is a strong diprotic acid; its first proton dissociates completely in water.
What is sulfuric acid used for?
As a food additive (E513), it’s used as an acidity regulator and processing aid for pH control, sugar refining, and starch modification; industrially it’s used for fertilizers, batteries, and chemical synthesis.
Is h2so4 an acid or base?
An acid—specifically a strong diprotic mineral acid used to acidify and catalyze reactions.
Is sulfuric acid a strong acid?
Yes; it’s considered a strong acid, with essentially complete first dissociation in water.
What does h2so4 do in a reaction?
It donates protons to acidify mixtures and can catalyze hydrolysis, esterification, and dehydration; in food processing it’s mainly used to adjust pH and is neutralized or removed afterward.
