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 sodium gluconate safe?
Yes—at permitted food-use levels it’s considered safe; EFSA found no safety concern for gluconic acid and its salts, though it does contribute sodium, which may matter on sodium-restricted diets.
What is sodium gluconate in soap?
It’s a chelating (sequestrant) agent that binds metal ions, helping prevent discoloration and rancidity and improving performance in hard water by reducing soap scum.
Is sodium gluconate gluten free?
Yes—sodium gluconate is inherently gluten-free; it’s made by fermenting glucose and contains no wheat proteins, though sensitive consumers should check for cross-contact claims from manufacturers.
What is sodium gluconate used for?
In foods it functions mainly as a sequestrant/stabiliser (and sometimes thickener) to bind metal ions and improve stability and texture; it’s also widely used industrially as a chelating agent in cleaning, water treatment, and concrete admixtures.
How to get sodium ferric gluconate?
Sodium ferric gluconate is an intravenous iron medicine (not the E576 food additive) and is obtained via prescription and administration by a healthcare provider.
