Have you ever glanced at the ingredient list on your favorite snack and noticed the phrase “natural flavors”? It sounds wholesome, right? But what if I told you that some of these so-called natural flavors actually come from beavers, bugs, or even mold? That’s right—your go-to granola bar or fruity drink might contain ingredients with origins you’d never expect. Understanding what “natural flavors” really mean can help you make more informed choices at the grocery store. Let’s focus on seven surprising sources of natural flavors hiding in your snacks, and why you should care.

1. Castoreum: The Beaver’s Secret Ingredient
Castoreum is a natural flavoring from the castor sacs of beavers, located near their tails. While it sounds bizarre, castoreum has been used for decades to add a vanilla-like aroma to foods, especially in desserts and candies. The FDA considers it safe, but it’s rarely listed by name—instead, it’s lumped under “natural flavors” on ingredient lists. If you’re vegan, vegetarian, or just squeamish, this is one natural flavor you’ll want to watch out for.
2. Carmine: The Red Dye from Bugs
You might eat carmine, a natural dye made from crushed cochineal insects, if you love vibrant red candies, yogurts, or juices. Carmine is prized for its rich color and is often found in products labeled as containing “natural color” or “natural flavors.” While it’s generally safe, some people can have allergic reactions, and it’s definitely not vegan-friendly. To avoid eating bugs, look for products that use plant-based colorings instead. The FDA provides more details on carmine and its labeling requirements.
3. Shellac: The Shiny Coating from Lac Bugs
That glossy finish on your jelly beans or chocolate-covered nuts? It might be shellac, a resin secreted by the female lac bug. Shellac is used as a natural glaze to give snacks a shiny, appealing look. While it’s considered safe to eat, it’s another example of a bug-derived ingredient hiding under the “natural flavors” umbrella. If you want to avoid animal products, check for “confectioner’s glaze” or “natural glaze” on the label, as these often mean shellac.

4. Amylase: Mold’s Role in Making Snacks Tasty
Amylase is an enzyme that helps break down starches into sugars, making snacks taste sweeter. Surprisingly, commercial amylase is often produced by fermenting certain molds, like Aspergillus oryzae. This enzyme is used in everything from bread to crackers to improve texture and flavor. While it’s generally safe and vegan, those with mold allergies might want to be cautious. If you see “enzymes” or “natural flavors” on a label, amylase could be part of the mix.
5. Vanilla Flavor: Sometimes from Wood Pulp or Beavers
Not all vanilla flavors come from vanilla beans. Some “natural vanilla flavor” is derived from lignin, a compound found in wood pulp, or castoreum (the beaver secretion again). These sources are used because they mimic the complex aroma of real vanilla at a lower cost. If you want the real deal, look for products labeled “vanilla bean” or “pure vanilla extract.” Otherwise, you might get a dose of wood or beaver in your cookies.
6. Monascus Red: Mold-Based Food Coloring
Monascus red is a natural food coloring made by fermenting rice with a specific mold called Monascus purpureus. It’s popular in Asian snacks and can be found in some Western products as well. While it’s a natural alternative to synthetic dyes, it’s still a mold-derived ingredient. If you’re sensitive to molds or prefer to avoid them, watch for “Monascus color” or “natural red” in the ingredients.
7. L-Cysteine: Feathers, Hair, and Microbes
L-Cysteine is an amino acid that improves the texture of baked goods and snacks. Traditionally, it was sourced from human hair or duck feathers, but today it’s often produced by fermenting bacteria or yeast. While it’s considered a natural flavor, its origins might surprise you. If you’re concerned about animal-derived ingredients, look for products labeled “vegan” or “plant-based,” as these are more likely to use microbe-derived L-Cysteine.
What “Natural Flavors” Really Means for Snack Lovers
The term “natural flavors” might sound reassuring, but as you’ve seen, it can cover many surprising—and sometimes unsettling—ingredients. These additives are more common than you might think, from beaver secretions to bug-based dyes and mold-fermented enzymes. The best way to know what you’re eating is to read labels carefully and look for transparent brands about their ingredients. If you have dietary restrictions or strong preferences, don’t hesitate to contact manufacturers for more information. Remember, being an informed snack lover means looking beyond the buzzwords and understanding what’s really in your food.
