Liquid Glucose

Description

Liquid glucose, also known as glucose syrup, is a viscous, clear liquid sweetener used widely in the food industry. It’s produced by the hydrolysis of starch, a process that breaks down the long starch molecules into smaller sugar units, primarily glucose. While it’s often made from corn starch, it can also be derived from other starchy sources like wheat, potatoes, or rice. This is why liquid glucose is sometimes called corn syrup, though not all glucose syrup is corn syrup.

Chemical properties

Uses

Liquid glucose is a valuable ingredient in a wide range of food products, not just for its sweetness but also for its functional properties:

Prevents Crystallization: It’s a key ingredient in candies, jams, and jellies because it prevents the crystallization of other sugars like sucrose, resulting in a smooth texture.

Humectant: It’s a powerful humectant, meaning it helps retain moisture in food, keeping baked goods, like cakes and cookies, soft and fresh for longer.

Adds Body and Texture: It adds volume and a smooth, thick consistency to products like ice cream, sauces, and beverages. In ice cream, it lowers the freezing point, which helps create a smoother, scoopable texture.

Enhances Appearance: It can give a glossy finish to glazes, frostings, and confectionery.

Liquid Glucose vs. Corn Syrup

The terms are often used interchangeably, but there is a slight distinction:

Liquid Glucose is the broader term for a syrup made from any type of starch.

Corn Syrup is a specific type of liquid glucose that is made exclusively from corn starch.

In the United States, corn syrup is the most common form of liquid glucose, so the names are used synonymously. However, in other parts of the world, liquid glucose may be sourced from other plants.
