E330 — Citric acid
E330 (Citric acid), a acidity regulator, is rated "safe": no significant concern. The most-used food acid in the world. Found naturally in lemons and limes. Used for sour taste, preservation, and as a chelating agent in almost every food category.
What is Citric acid?
The main acid in lemons, limes, and other citrus fruit. Produced industrially by fermentation. Used in nearly every soft drink, candy, sauce, and canned good.
What does it do to the body?
Part of your body's central energy cycle (the Krebs cycle), so it gets burned as fuel. No realistic safety concern at food levels. Heavy consumers of acidic drinks can experience tooth enamel erosion over time, but that is the acidity, not the additive itself.
What regulators say
EFSA and the FDA both treat it as a safe additive with no numerical limit.
Risk rating: Safe
Cleared by EFSA with no significant concern at typical dietary exposure. Common, well-studied, and not a reason to put a product back on the shelf.
