What Are Other Words for High Fructose Corn Syrup?

December 11, 2025 •

2 min read

Over 90% of global food manufacturing sweeteners are sucrose, however in the United States, usage of high fructose corn syrup (HFCS) is nearly equal to that of sucrose, emphasizing its widespread use. Many manufacturers use different names for this additive because of its negative public perception.

Quick Summary

HFCS is often hidden under alternative names like glucose-fructose syrup or isoglucose. Identifying these terms is important for making smart dietary decisions and understanding ingredients.

Key Points

Glucose-Fructose Syrup: A common European alias for HFCS, often containing similar sugar ratios.
Crystalline Fructose: Can be another name for processed fructose derived from corn starch.
Isoglucose: The official European Union term for syrups with a specific fructose content, including HFCS.
Corn Sweetener: A generic term that can indicate the presence of corn-derived sweeteners, including HFCS.
Maize Syrup: The international term for corn syrup, referring to a corn-based sweetener.
Reading Labels is Key: The most effective way to avoid hidden HFCS is by carefully scrutinizing the ingredient list.
Multiple Sources: Manufacturers may use a mix of different sweeteners to mask the total sugar content.

Decoding the Common Aliases of High Fructose Corn Syrup

High fructose corn syrup (HFCS) is a processed sweetener made from corn starch. Manufacturers often use alternative names on ingredient lists due to its negative public perception and health concerns.

List of Common Hidden Names for HFCS

Be aware of these alternative names on food labels:

Glucose-Fructose Syrup: A common European term for syrups from starch with glucose and fructose.
Isoglucose: The official EU name for starch-based syrups with a specific fructose content, like HFCS.
Maize Syrup: Another term for corn syrup, where 'maize' means corn.
Corn Syrup: While structurally different from HFCS, this broad term may sometimes imply higher fructose.
Corn Sweetener: A general term that can include various corn-derived sweeteners, including HFCS.
Crystalline Fructose: A concentrated form of fructose, potentially from corn starch.
Fructose: This general term can refer to corn-derived fructose, not just from fruit.
Corn Syrup Solids: The dehydrated version of corn syrup.

The Motivation Behind Disguising Ingredients

Manufacturers use alternative names for marketing and regulatory reasons. This helps avoid negative consumer associations with HFCS and can align with regional labeling rules, especially in the EU where 'glucose-fructose syrup' is common.

Products Where You Can Find Hidden HFCS

HFCS is widely used beyond soft drinks, serving as a preservative and flavor enhancer. Check labels carefully on:

Baked Goods.
Condiments.
Snacks.
Breakfast Cereals.
Canned and Packaged Goods.

Comparison of Corn-Derived Sweeteners

This table highlights differences between various corn-based sweeteners:


Feature	Corn Syrup	High Fructose Corn Syrup (HFCS)	Glucose-Fructose Syrup (GFS)
Composition	Primarily glucose	Mix of glucose and fructose	Mix of glucose and fructose
Processing	Corn starch broken down into glucose by enzymes.	Corn syrup processed to convert some glucose into fructose.	Starch broken down to glucose, some converted to fructose.
Sweetness	Less sweet than table sugar.	Can be similar to or sweeter than table sugar (HFCS 42 or 55).	Varies with fructose percentage.
Common Use	Preserves moisture, prevents crystallization.	Widely used in beverages, cereals, and processed foods.	Sweetener/preservative in liquids/semi-solids like beverages and jams.
Regional Term	Varies; sometimes Glucose Syrup.	HFCS in US; Isoglucose or GFS in Europe.	GFS or Isoglucose in Europe.

Conclusion

Knowing the various terms for high fructose corn syrup is essential for informed dietary choices. Examining ingredient lists carefully helps identify this common additive, regardless of the name used. Look beyond front-of-package claims and check for corn-based sweeteners like isoglucose, corn sweetener, or glucose-fructose syrup to manage processed sugar intake. Reading ingredient lists is key to reducing consumption of processed sugars.

Frequently Asked Questions

No, the FDA rejected a petition by the Corn Refiners Association to rename HFCS 'corn sugar.' The term 'corn sugar' refers specifically to dextrose, which is chemically distinct from HFCS.

Manufacturers use different names due to reasons including negative consumer perception, marketability, and regional regulatory requirements. Using a less familiar term can make the product seem more appealing or 'natural' to shoppers.

They are very similar products. Glucose-fructose syrup is a mix of glucose and fructose and is the common terminology for HFCS in Europe. The fructose content can vary but the composition is comparable.

The most common types are HFCS 42 and HFCS 55, which denote the percentage of fructose content by dry weight (42% and 55%, respectively). HFCS 42 is often in processed foods, while HFCS 55 is typically found in soft drinks.

Yes, a product labeled 'natural corn syrup' can still contain high-fructose variations. The best way to be sure is to check for specific ingredients like 'glucose-fructose syrup' or 'crystalline fructose' on the label.

Look for ingredients ending in '-ose' (like dextrose, maltose, sucrose), various syrup names (corn syrup, rice syrup, maize syrup), and fruit juice concentrates.

It is widely used in soft drinks, ketchup, bread, breakfast cereals, baked goods, condiments, and many other processed foods and beverages.
