Popular questions
Is ascorbic acid bad for you?
No—ascorbic acid (vitamin C) is considered safe at typical food levels and is essential for health; it’s GRAS in the U.S. and approved in the EU. Very high supplemental doses can cause gastrointestinal upset and, in susceptible people, increase kidney stone risk.
Can dogs have ascorbic acid?
Yes, small amounts in foods are safe, but dogs synthesize their own vitamin C and usually don’t need supplements. High doses may cause diarrhea, so consult a veterinarian before supplementing.
What is ascorbic acid made from?
Commercial ascorbic acid is typically made from glucose (often derived from corn, wheat, or cassava) that’s converted via microbial fermentation and chemical steps into L‑ascorbic acid.
How is ascorbic acid made?
Industrially, D‑glucose is converted to 2‑keto‑L‑gulonic acid by fermentation (or via the older Reichstein process: glucose → sorbitol → L‑sorbose → 2‑KGA) and then chemically cyclized to ascorbic acid. Modern methods use two-step fermentation to improve efficiency.
Is ascorbic acid the same as citric acid?
No—ascorbic acid (E300) is vitamin C and an antioxidant, while citric acid (E330) is a different compound mainly used as an acidulant and does not provide vitamin C.
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.
