Popular questions
What is tannin in wine?
Tannins are natural polyphenols from grape skins, seeds, stems, and oak that give wine its mouth-drying astringency and structure, helping stabilize color and support aging.
What is a tannin?
A tannin is a plant-derived polyphenolic compound (E181) that binds proteins and other molecules, causing astringency and sometimes used in foods for color and stabilization.
What is tannin bleed?
Tannin bleed is yellow-brown staining that occurs when water‑soluble tannins migrate from wood through paint or coatings; it’s minimized with stain‑blocking primers and proper sealing.
What is tannin in tea?
In tea, “tannins” are polyphenols (such as catechins and theaflavins) that cause bitterness and a puckering, astringent feel, which intensifies with longer steeping.
What is a tannin in wine?
In wine, tannins are grape- and oak-derived polyphenols that contribute bitterness and a drying mouthfeel while adding structure and age‑worthiness.
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.
