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.
What foods have potassium bromate?
Primarily products made with 'bromated flour'—such as some breads, rolls, bagels, and pizza crusts—where it strengthens dough and improves rise. It’s banned in the EU/UK/Canada, and many U.S. bakers have phased it out.
What foods contain potassium bromate?
Where permitted (e.g., parts of the U.S.), certain commercial bakery items made with bromated high‑gluten flour may contain it, especially bread and pizza dough.
What brands use potassium bromate?
Usage varies by region and over time; in the U.S., some foodservice pizza/bread flours labeled 'bromated' use it, while many national retail brands and chains avoid it, and it’s banned in the EU/UK/Canada. Check labels for 'bromated flour' to confirm.
Does king arthur flour have potassium bromate?
No—King Arthur Baking Company states its flours are never bromated (and never bleached).
What is potassium bromate in?
It’s in bromated wheat flour used as a flour improver for yeast‑leavened doughs like bread, rolls, bagels, and pizza. Look for 'bromated flour' or E924a on ingredient lists where it’s allowed.
