Notes

Originally extracted from citrus fruit (hence the name), commercial citric acid has been produced via Aspergillus niger fermentation since 1919 — the citrus extraction route was immediately rendered uneconomic. Approximately 2.8 million tonnes are produced annually, with China accounting for approximately 70% of global output. Vegan and generally recognised as safe. Occasionally causes mouth sores in sensitive individuals at high doses.
