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.
Calcium peroxide – what it is: bleaching agent and dough conditioner?
Calcium peroxide (E930) is a synthetic flour treatment agent that releases oxygen, acting as a bleaching agent to whiten flour and as a dough conditioner to strengthen gluten and improve texture. It is used at very low levels and is almost insoluble in water.
Calcium peroxide how long has this chemical been around?
It has been known since the early 20th century, with food-related uses (e.g., flour treatment) established for several decades. Its approval and use vary by country.
How do you use baking soda and peroxide on granite counter tops to remove calcium?
That method typically refers to hydrogen peroxide, not calcium peroxide (E930); calcium peroxide is a food additive and not intended for stone cleaning—use granite-safe cleaners per the manufacturer’s guidance.
How do you use baking soda and peroxide on granite countertops to remove calcium?
This refers to hydrogen peroxide rather than calcium peroxide (E930); the food additive isn’t suitable for cleaning granite, so follow stone-care products and instructions instead.
How do you use dental calcium peroxide paste with idofrm?
Dental pastes commonly use calcium hydroxide with iodoform, not calcium peroxide; E930 is a flour treatment additive and should not be used for dental applications—follow product labeling or a dentist’s guidance.
