The Official FDA Definition
In the United States, the definition of "natural flavoring" is dictated by the U.S. Food and Drug Administration (FDA) under the Code of Federal Regulations, specifically 21 CFR 101.22. This regulation provides a surprisingly broad definition. A natural flavoring is defined by the FDA based on its source. It must contain flavoring constituents derived from plant material like spices, fruits, vegetables, or herbs, or from animal sources such as meat, seafood, poultry, eggs, or dairy products. The key function in food must be flavoring, not nutrition. This means the main distinction from artificial flavors is that natural flavors must originate from a plant or animal.
The Source vs. The Process
While the source must be natural, the process to create the final flavor often involves sophisticated laboratory techniques to isolate, extract, and blend flavor compounds. Flavorists, or food chemists, develop these additives. For example, a strawberry flavor might not come solely from strawberries but be a blend of extracts from various natural sources to create a specific flavor profile. This blend is then diluted with a carrier. As long as the base flavor constituents come from natural sources, the end product is legally classified as "natural flavoring".
How Natural Flavors are Created in the Lab
Creating a natural flavor is a complex process. Key steps include:
- Source Selection: Flavorists choose natural materials like fruits or spices.
- Extraction: Various methods like distillation or solvent extraction are used. Synthetic solvents are permitted if the original flavoring constituent is natural.
- Isolation and Blending: Compounds are isolated and blended to create a consistent flavor profile. Blends can contain over 100 chemicals, including solvents and preservatives, often not listed on the label.
- Dilution: The flavor concentrate is diluted with carriers like water or ethanol.
This lab process allows natural flavors to be more intense and stable than fresh ingredients.
Natural vs. Artificial Flavoring: A Comparison
Despite the source difference, the chemical composition of natural and artificial flavors can be similar. Both are complex chemical mixtures created in a lab. Differences lie in cost, consistency, and regulation. Here is a comparison:
| Feature | Natural Flavoring | Artificial Flavoring |
|---|---|---|
| Source | Derived from natural materials (plants, animals, etc.). | Synthesized from non-natural, chemical sources. |
| Production | Involves extraction and blending from natural sources in a lab. | Created entirely in a laboratory using synthetic compounds. |
| Cost | Generally more expensive. | More cost-effective. |
| Consistency | Can have minor variations. | Offers high consistency and stability. |
| Additives | Can contain processing aids and preservatives, some synthetic, without being labeled. | May contain fewer chemical components but are entirely synthetic. |
Potential Health and Dietary Considerations
The term "natural" is often seen as healthier, but this is a misconception. Both natural and artificial flavors are considered safe at approved levels. Safety depends on the chemical composition and concentration, not the source.
- Lack of Transparency: Specific ingredients in 'natural flavor' blends don't require disclosure. This can be an issue for those with sensitivities or allergies.
- Dietary Restrictions: Natural flavors can come from animal sources (meat, dairy, eggs), meaning they are not automatically vegan or vegetarian. Consumers with strict diets may need to contact manufacturers to confirm the source. While rare now, some flavors were historically derived from animal glands.
- Ultra-Processed Foods: The presence of flavors often indicates a highly processed food. Diets high in ultra-processed foods are linked to health risks. Focusing on whole, unprocessed foods is recommended.
Conclusion
What is natural flavouring in the USA is a complex and often misunderstood topic. The FDA's definition focuses on the source material, not the processing or other chemicals involved. Both natural and artificial flavors are lab-developed and can have similar chemical compositions. Consumers should understand that "natural" doesn't automatically mean "healthier" or "less processed." Due to a lack of labeling transparency, those with allergies or specific dietary needs may need to contact the manufacturer for detailed information. Informed dietary choices require looking beyond simple label claims.
