What Exactly are Natural Flavors in Halloween Candy?

If candy manufacturers were required to declare the exact ingredients found in candy, the label would read like something out of a witch’s brew: dried beaver’s sac, sheepskin excretions or insect excretions. This may sound more like “trick” than “treat,” but it’s true. When it comes to the ingredient “natural flavors,” it is considered a trade secret and, as a result, does not require disclosure from manufacturers. So, what exactly are “natural flavors” and just how natural are they?

According to the Food and Drug Administration (FDA) here’s the official definition of natural flavors:

“(3) The term natural flavor or natural flavoring means the essential oil, oleoresin, essence or extractive, protein hydrolysate, distillate, or any product of roasting, heating or enzymolysis, which contains the flavoring constituents derived from a spice, fruit or fruit juice, vegetable or vegetable juice, edible yeast, herb, bark, bud, root, leaf or similar plant material, meat, seafood, poultry, eggs, dairy products, or fermentation products thereof, whose significant function in food is flavoring rather than nutritional. Natural flavors include the natural essence or extractives obtained from plants (identified in other sections of the document).”

While it’s a bit intense, on the surface it seems fairly harmless too. But, there are a few issues:

Odd and unwanted ingredients

Because the single ingredient of natural flavors can contain 100 other ingredients, there is room for a lot of potentially unwanted substances in foods containing this enigmatic ingredient. Some candy manufacturers exploit the definition to include ingredients like castoreum—found in the dried castor sacs (near the anus) of beavers—while this ingredient is technically “natural” in that it is derived from meat, it’s not something most people would knowingly choose to eat. Nor is confectioner’s glaze or shellac, which gives many candies their shiny coating, but it is actually extracted from the excretions of certain insects found in India and South Asia.

Potential for allergens

If you have a severe food allergy, such as seafood, you’re better off staying clear of any candy (or any other food for that matter) that contains natural flavors. As you may have noticed from the FDA description, natural flavors can be derived from seafood, among other potential allergens. The same is true if you have an egg or dairy allergy. You may be at risk of an allergic reaction when consuming candies that contain natural flavors.

Potential for GMOs

Because genetically-modified organisms currently have GRAS status “generally-recognized as safe” genetically-modified dairy products, corn, soy or other GMO food can be used in the process of obtaining natural flavors. GMO foods have been linked in studies to reproductive disorders, cancer and other serious health concerns, so candy containing natural flavors may not be suitable for you or the children who are consuming it in droves this Halloween.

Solvents and pesticides

There are frequently residues of solvents (usually petroleum-based) used in the extraction of certain flavors from plant or animal sources. Additionally, because the foods used to manufacture natural flavors is probably not organic, the ingredient “natural flavors” tends to have pesticide residues as well.

Sometimes natural flavors are listed as “natural flavor (organic vanilla)” or “natural flavor (organic peppermint),” or something similar on labels. In these cases, the candy is probably devoid of the unwanted ingredients sometimes found in natural flavors and is likely safe to eat. But, considering that “natural flavors” is the fourth most used ingredient in processed foods, after salt, water and sugar, unwanted or questionable ingredients are found in a lot of our foods, and certainly a lot of the Halloween candy being distributed to children.

Any harmful effects of these sweets happens after the wrapper has been thrown on the ground... so its damages are twofold. First to the environment then to our children or ourselves.

Real all-natural flavourings are usually suitable for vegetarians. If that label is not on the packet, wonder why not.

Thanks, mostly the fruit sweets here are coloured with nettle, elder and liquorice.

Here any additive has an E-number and the fact that it has this number means it is safe - not necessarily what you want to eat though.

The problem of "additives" is in most things. The recent one that was an eyeopener to me is generic drugs. No doubt there are good and bad additives but one often wonders why there has to be so many of them in such wide ranging products.
