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.
How long to soak oats to remove phytic acid?
About 12–24 hours in warm water with a little acid (e.g., yogurt or lemon) plus a phytase source such as rye flour or sourdough can substantially reduce phytic acid; a plain cold overnight soak removes relatively little.
How to remove phytic acid from oats?
Soak oats 12–24 hours in warm water with a small amount of acid and a phytase-rich addition (e.g., rye flour or sourdough), then cook and discard the soak water; this activates enzymes that break down phytic acid. Fermenting into a sour porridge or sprouting also helps, while plain soaking alone is less effective.
Does white rice have phytic acid?
Yes, but at much lower levels than brown rice because most phytic acid is in the bran and germ that are removed during polishing; white rice typically contains only trace-to-low amounts.
How long to soak cashews to remove phytic acid?
Soak 2–4 hours to soften and reduce a little phytic acid; extending to 8–12 hours in warm, lightly salted or acidic water may help slightly more, but significant reduction usually requires additional steps like boiling or roasting.
How to soak oats to remove phytic acid?
Cover oats with warm water, add a spoonful of acidic medium (yogurt/lemon) and a phytase source (rye flour or sourdough), soak 12–24 hours, then cook and discard the soaking liquid for best phytic acid reduction.
