Finding Erythritol on Food Labels
When searching for erythritol on a packaged food item, the most reliable place to start is the ingredients list, not the Nutrition Facts table alone. By law, all ingredients must be declared here. Erythritol, as a common sugar alcohol, is typically listed by its full name. However, discerning consumers should be aware of several nuances in how manufacturers disclose this ingredient.
Where to look first: The ingredients list
In the U.S., the FDA requires ingredients to be listed in descending order by weight, meaning the closer erythritol is to the top of the list, the more of it the product contains. Many products, particularly those marketed as 'sugar-free' or 'keto-friendly,' will clearly state "erythritol" in the ingredients. For example, a low-carb candy bar might list "Chocolate, Erythritol, Soluble Corn Fiber..." as its primary components.
The 'sugar alcohol' label and what it means
Sometimes, manufacturers will use the general term "sugar alcohol" instead of listing erythritol specifically on the Nutrition Facts panel, especially if multiple sugar alcohols are present. In this case, you must scrutinize the ingredients list for the specific names. Common sugar alcohols alongside erythritol include xylitol, mannitol, and sorbitol. For a person with a sensitivity to one sugar alcohol but not another, relying solely on the "Sugar Alcohol" line can be misleading.
The voluntary nature of disclosure on the Nutrition Facts panel
Manufacturers have some flexibility in how they present erythritol on the Nutrition Facts panel, specifically the line item for "Sugar Alcohols". It is important to remember:
- Listing sugar alcohols on the Nutrition Facts panel is voluntary unless a health-related claim about sugar alcohols is made on the packaging.
- Even when listed, this line item represents the total of all sugar alcohols combined, not just erythritol.
- The absence of the "Sugar Alcohols" line does not mean the product is free of erythritol, it simply means the manufacturer did not choose to report it there.
Deciphering the Fine Print on Keto and Low-Carb Products
Erythritol is a staple in many ketogenic and low-carb products because it has minimal impact on blood sugar and is largely unabsorbed by the body. Consumers of these products often use a "net carb" calculation, which involves subtracting fiber and sugar alcohols from the total carbohydrates. This is why clear labeling is so critical for this demographic.
The net carb dilemma
For most people on a keto diet, erythritol is a zero-net-carb sweetener, making it a desirable ingredient. However, other sugar alcohols, like maltitol, have a higher glycemic index and can raise blood sugar. The practice of simply labeling "sugar alcohol" could hide the presence of these less-keto-friendly alternatives. Consequently, reading the full ingredient list is essential for accurate net carb counting.
Other common names and brand names
Erythritol is not typically hidden under chemical-sounding alternative names in the same way some artificial sweeteners might be. However, it can sometimes be part of a branded sweetener blend. For instance, the sugar substitute Swerve is a blend of erythritol and oligofructose. The ingredients list should still clarify the individual components. The European food additive number is E968.
Comparison Table: How Erythritol Is Labeled vs. Other Sweeteners
| Sweetener | Ingredient List Disclosure | Nutrition Facts Panel | Examples | Special Notes |
|---|---|---|---|---|
| Erythritol | Listed explicitly as "Erythritol". | Can be grouped under the optional "Sugar Alcohol" line, but isn't always. | Keto desserts, sugar-free gum, some ice creams. | Minimal calorie impact, widely used in low-carb products. |
| Xylitol | Listed explicitly as "Xylitol". | Can be grouped under the optional "Sugar Alcohol" line. | Sugar-free gum, mints. | Known to be toxic to dogs, important to identify on pet products. |
| Maltitol | Listed explicitly as "Maltitol". | Often under the optional "Sugar Alcohol" line. | Some sugar-free chocolates and candies. | Can raise blood sugar more than other sugar alcohols; important for keto users. |
| Sucralose | Listed explicitly as "Sucralose". | Not listed separately, as it's a non-nutritive sweetener. | Splenda packets, Diet soda. | A high-intensity sweetener, not a sugar alcohol. |
| Steviol Glycosides | Listed explicitly as "Steviol Glycosides" or "Stevia Leaf Extract". | Not listed separately, as they are GRAS high-intensity sweeteners. | Truvia packets, some beverages. | High-purity extracts are GRAS, but crude leaf extract is not. |
A Step-by-Step Guide to Identifying Erythritol
For consumers with dietary concerns or simply wishing to monitor their intake, follow these steps to confidently identify erythritol:
- Locate the Ingredients List: This is the most important step. Don't stop at the Nutrition Facts panel.
- Scan for Keywords: Look for the specific word "erythritol." It will be listed by name.
- Check for "Sugar Alcohol" and Other Sweeteners: If the ingredients list mentions "sugar alcohols," cross-reference this with the Nutrition Facts panel. While it doesn't guarantee erythritol is present, it's a strong indicator. Read the full ingredients list for other common sugar alcohols like xylitol, maltitol, and sorbitol.
- Look for Branded Blends: Be mindful of proprietary sweetener blends like Swerve, which contain erythritol but might list it alongside other ingredients.
- Look for the European Additive Code: In some regions, or on imported products, the code E968 may be used.
Conclusion: Informed Label Reading is Key
Yes, erythritol is listed on ingredients when used in food products. However, relying on the optional "Sugar Alcohols" line on the Nutrition Facts panel is an incomplete strategy, especially for those with specific dietary needs like keto or sensitivities to other sugar alcohols. The most accurate and reliable method for determining the presence of erythritol is to always check the detailed ingredients list. By understanding the regulations and what to look for, consumers can navigate complex food labels and make confident choices about what they are eating.
