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 is a protease?
A protease (E1101) is an enzyme that catalyzes proteolysis—cutting peptide bonds to break proteins into smaller fragments.
What does protease do?
In foods, E1101 proteases break down proteins to modify texture and processing—for example tenderizing meat, improving dough handling, clarifying beer, and creating protein hydrolysates.
What does protease break down?
Proteases break down proteins into peptides and amino acids by hydrolyzing peptide bonds.
What is a protease inhibitor?
A protease inhibitor is a substance that blocks protease activity; some occur naturally in foods (e.g., in legumes), and others are used as drugs to inhibit specific proteases.
Where is protease produced?
Proteases are made by animals, plants, and microorganisms; for food use (E1101) they are commonly produced by microbial fermentation (e.g., Aspergillus or Bacillus) or extracted from sources like papaya or pineapple, and less often from animal tissues.
