Ascorbic acid (vitamin C)

Group: Antioxidants · in the book

Harm level1 of 5No concern

In plain words

It is vitamin C, which prevents oxidation in food so it stays fresh longer and does not brown. You find it in juices, fruit products, baked goods, meat products and drinks.

Where you find it: juices, meat products, bread, canned fruit

Our recommendation

No need to avoid it.

Possible risks and effects

  • No relevant risk known at normal intake.
  • In drinks with benzoates (E210–E213) it can contribute to benzene formation.

For experts

L-ascorbic acid is a water-soluble vitamin and reducing agent that scavenges oxygen and free radicals; in baking it strengthens the gluten network and in meat products it inhibits nitrosamine formation. It is produced mainly by combined fermentation and chemical synthesis from glucose. EFSA re-evaluated it in 2015 and saw no need for a numerical ADI.
