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 does glucose oxidase do?
It’s an enzyme that oxidizes glucose to D-glucono-delta-lactone (which becomes gluconic acid) while producing hydrogen peroxide and consuming oxygen; in foods it acts as an oxygen scavenger/antioxidant and can strengthen dough.
Cytochrome oxidase is used in which stage of the aerobic respiration of glucose?
Cytochrome c oxidase works in the electron transport chain (oxidative phosphorylation), the final stage of aerobic respiration; this is a different enzyme from the food additive glucose oxidase (E1102).
Glucose oxidase produces what?
Hydrogen peroxide and D-glucono-delta-lactone (which hydrolyzes to gluconic acid), while consuming oxygen.
How does glucose oxidase work?
It is an FAD-dependent oxidoreductase that binds beta-D-glucose, oxidizes it to D-glucono-delta-lactone, and reduces oxygen to hydrogen peroxide—removing oxygen and generating a mild antimicrobial oxidant.
How much hydrogen peroxide does glucose oxidase produce?
Stoichiometry is 1 mole of H2O2 per mole of glucose oxidized (about 34 mg H2O2 per mmol of glucose); in foods the actual amount formed depends on available glucose and oxygen and may be further decomposed or consumed.
