About
Citrus extract is a broad category of ingredients derived from the peel, seed, pulp, or pith of citrus fruits (e.g., lemon, orange, grapefruit, lime), containing bioactive compounds such as flavonoids, essential oils, polyphenols, and organic acids. It is used in food as a natural preservative/antioxidant, flavouring agent, and texturizer to extend shelf life and enhance sensory qualities.
Safety summary
Citrus extract in food-grade forms is broadly considered safe for the general adult population, with no established ADI and a long history of use; individual components (e.g., lemon extract) are recognised as GRAS by the FDA. At high supplemental doses, certain fringe products (e.g., concentrated grapefruit seed extract) may interact with cytochrome P450 drug metabolism. Citrus-sensitive individuals or those with citrus allergies may experience reactions.
Regulatory landscape
| Jurisdiction | Status | Note |
|---|---|---|
| FSANZ (Food Standards Australia New Zealand) (Australia) | Approved | Citrus extracts are permitted as natural flavourings and antioxidants under FSANZ Food Standards Code Standard 1.3.1. No specific INS number assigned to generic citrus extract.source |
| EFSA (European Food Safety Authority) (European Union) | Approved | Citrus extracts are permitted in the EU as natural flavourings and antioxidants under Regulation (EC) No 1334/2008 (flavourings) and Regulation (EC) No 1333/2008 (food additives). No specific E-number has been assigned to generic 'citrus extract'; specific components such as citric acid (E330) and ascorbic acid from citrus (E300) carry separate E-numbers. Conditions of use governed by quantum satis (good manufacturing practice) where no numerical maximum is specified.source |
| FSSAI (Food Safety and Standards Authority of India) (India) | Approved | Natural citrus extracts used as flavourings and antioxidants are permissible under FSSAI Food Safety and Standards (Food Products Standards and Food Additives) Regulations. Specific components such as citric acid (INS 330) are explicitly listed. Quantum satis applies for natural flavourings.source |
| FDA (Food and Drug Administration) (United States) | Approved | Lemon extract (Citrus limon) and other individual citrus extracts are listed in FDA's Substances Added to Food inventory as GRAS flavouring substances. Citrus bioflavonoids listed under 21 CFR as dietary supplement ingredients. Citrus fiber recognised GRAS (GRN 599) as texturizer/moisture retention agent at up to 4–5% in select foods. |
