Corn Syrup vs. Liquid Glucose: Know the Difference
By Shumaila Saeed || Published on February 17, 2024
Corn syrup, a food syrup made from corn starch, contains varying amounts of glucose and other sugars. Liquid glucose, typically derived from starch, is a concentrated glucose solution, often used in confectionery and baking.
Key Differences
Corn syrup is a sweet, thick liquid made by breaking down cornstarch, primarily composed of glucose but also containing other sugars like maltose. It is often used in baking and candy making due to its ability to prevent crystallization and retain moisture. Liquid glucose, on the other hand, is a syrup containing a high concentration of glucose, produced from starch sources like wheat, corn, or potatoes. It is particularly valued in confectionery for its high boiling point and ability to control sugar crystallization.

Corn syrup can be light or dark, with dark corn syrup having a more pronounced flavor due to the addition of molasses. Liquid glucose is generally clear and colorless, with a neutral flavor, making it a versatile ingredient in various culinary applications.
