Corn Syrup vs. Liquid Glucose: What's the Difference?

Edited by Huma Saeed || By Sara Rehman || Updated on November 17, 2023

Corn syrup is a sweet, thick liquid made from cornstarch, often used in baking and candy making, while liquid glucose is a syrup made from starches like wheat and corn, used as a sweetener and thickener.

Key Differences

Corn syrup is a sweet syrup derived from cornstarch, primarily composed of glucose, and used in various culinary applications, especially in candy making and baking. Liquid glucose, also known as glucose syrup, is a syrup made from the hydrolysis of starches, such as corn, wheat, or potatoes, and contains varying amounts of glucose, maltose, and other sugars. Both are used as sweeteners and texturizers in food production, but they have different compositions and properties.

In terms of sweetness, corn syrup is less sweet than table sugar and is often used to provide sweetness without overpowering the flavor of the dish. Liquid glucose, while also not as sweet as sugar, is used to control sugar crystallization in confections, contributing to a smooth texture. Both corn syrup and liquid glucose are effective in preventing crystallization in candies and frozen desserts.

Corn syrup can add volume, enhance texture, and extend the shelf life of foods, making it a versatile ingredient in the kitchen. Liquid glucose is similarly used to improve texture and stability in foods like ice creams, sorbets, and baked goods. Both are hygroscopic, meaning they attract and hold water, which is beneficial in preventing foods from drying out.

In the production process, corn syrup is made by breaking down cornstarch into glucose through enzymatic processes. Liquid glucose, on the other hand, is produced by hydrolyzing various starch sources, leading to a mixture of different sugars, primarily glucose. The source of the starch and the specifics of the production process can affect the flavor and properties of both corn syrup and liquid glucose.

Nutritionally, both corn syrup and liquid glucose are high in calories and carbohydrates, with minimal nutritional value beyond this. They should be used in moderation, particularly for individuals watching their sugar intake. While they serve similar purposes in cooking and baking, their slight differences can affect the outcome of a recipe.
