E330: Citric acid

What it does

Adds a sour taste and preserves.

What it is made from

Made by fermenting sugars with a mould (Aspergillus niger). The sugar is usually corn-based. It is not extracted from citrus fruit.

Allergies and diets

• Corn (maize)? Can be made from corn (maize).

Good to know if you avoid citrus terpenes: commercial citric acid is made by fermentation, not from citrus peel.
