For many health-conscious consumers, flavored seltzer has become a go-to beverage, offering a crisp, bubbly alternative to sugary sodas. The label 'natural flavors' is often a major selling point, but its meaning can be surprisingly complex. While the term suggests a simple, wholesome addition, the reality involves intricate extraction processes and broad regulatory definitions. By breaking down the official rules and methods behind these flavorings, we can gain a clearer understanding of what is actually in our favorite flavored seltzer.
The Official FDA Definition of "Natural Flavors"
The U.S. Food and Drug Administration (FDA) provides a specific legal definition for the term "natural flavor" under its regulations (21 CFR 101.22). It defines natural flavors as substances derived from a natural source whose primary function is flavoring, not nutrition. These sources include a wide range of materials such as:
- Spices, fruits, or vegetables
- Edible yeast, herbs, barks, buds, roots, or leaves
- Meat, seafood, poultry, eggs, or dairy products
This broad definition means the exact source or process isn't always clear from the label.
Where Natural Seltzer Flavors Come From and How They Are Made
Contrary to popular belief, a natural flavor like raspberry might not come from raspberries but from other natural sources that contain similar chemical compounds, like raspberry ketone found in cedarwood oil. Flavor scientists isolate and blend these compounds from various natural ingredients. These concentrated flavorings are used in tiny amounts, allowing seltzers to have zero calories and sugar.
The process of creating natural flavors involves various scientific methods to extract desired compounds:
- Distillation: Heating material with steam to vaporize and condense essential oils.
- Cold Pressing: Mechanically pressing citrus peels at low temperatures to release oils.
- Fermentation: Using microorganisms to convert sugars into flavorful compounds.
It's important to note that some extraction processes may use additives or solvents that are not required to be listed on the ingredients label. Organic certification, however, prohibits the use of synthetic solvents, offering a stricter standard.
Natural vs. Artificial: What's the Real Difference?
Many consumers wonder about the difference between natural and artificial flavors. The main distinction lies in their origin: natural flavors come from natural sources, while artificial flavors are synthesized in a lab. However, the final chemical composition can be identical.
| Feature | Natural Flavor | Artificial Flavor |
|---|---|---|
| Source | Derived from plant, animal, or microbiological materials. | Created from synthetic chemicals. |
| Sourcing Example | Banana flavor (amyl acetate) from bananas or apricot pits. | Banana flavor (amyl acetate) synthesized in a lab. |
| Consistency | Can vary naturally. | Offers high consistency. |
| Cost | Often more expensive. | More cost-effective. |
| Consumer Perception | Generally perceived as healthier. | Often viewed with suspicion. |
Is "Natural" Always Healthier?
The term 'natural' is often used for marketing, but it doesn't automatically mean a product is healthier or less processed. Natural flavors are lab-processed to isolate compounds. Nutritionally, the flavor molecules themselves often have negligible value, whether natural or artificial. Also, natural flavors can be derived from allergens, so those with allergies should check with the manufacturer.
Making an Informed Choice
Understanding the definition of natural flavors helps consumers make informed decisions. For hydration without sugar, both natural and artificial flavors can work. If avoiding synthetic chemicals is a priority, look for USDA Certified Organic products, which have stricter flavor standards. Ultimately, the choice between natural and artificial flavorings can often come down to personal preference.
Conclusion
In summary, 'natural flavors' in seltzer represent complex food additives derived from a wide range of natural sources according to a broad FDA definition. They are created through technical lab processes, and while their origin is natural, the final flavor molecules can be identical to artificial ones. 'Natural' does not inherently mean healthier or less processed. Consumers seeking the purest option might consider infusing plain seltzer with fresh fruit.
