What is Liquid Glucose – Definition, Uses, Alternatives, and Benefits

Do you know what liquid glucose is? I’m sure you do if you’ve ever used a glucose test strip in the past. But what actually is it? And why should you care?

Liquid Glucose is a ready-to-use solution of glucose (sugar) made from the hydrolysis of starch. It has a high solubility in water or other liquids. This makes it suitable for making solutions for testing blood sugar levels and other uses.

It can be seen under the names pure fructose and sucrose (in natural form). You might have also heard of this sweetener as maltose or dextrose. In this article, I will discuss all you need to know about liquid glucose, including general information and uses.

What is Liquid Glucose?

Liquid glucose solution is a simple, non-toxic liquid sweetener that can be used in commercial foods to improve their taste. It’s also safe for use as a home treatment and has been used safely by millions of people worldwide. It contains no additives, preservatives, or artificial colors. It is also gluten-free and Kosher-approved.

Liquid glucose is not to be confused with blood glucose, which is the main source of fuel for the body. Blood glucose is made up of a combination of sugars: glucose, fructose, and galactose. These three sugars are found in many foods and beverages such as fruit, milk, and baked goods.

Furthermore, Liquid glucose is not the same as powdered sugar. It has a different consistency and taste. It’s also called “high-fructose corn syrup” because it contains about half as much fructose as regular sugar does.

Liquid Glucose Vs Corn Syrup

You might be wondering what the difference is between corn syrup and liquid glucose. The one difference you need to know about is that corn syrup is easier to find in supermarkets has higher water content and is slightly more sweet than liquid glucose.

It can be substituted for glucose but you need to adjust your recipe for the extra water content in corn syrup. In general, corn syrup is used when you need something that’s lower in calories than regular table sugar, or when you want a product that doesn’t crystallize as easily.

Corn syrup also contains more fructose than table sugar does, which means it will cause your blood sugar levels to spike quicker after eating it than regular table sugar would.

However, since most people can have their blood sugar levels controlled by eating only small amounts of food with high fructose corn syrup in them, this isn’t such a big deal for most people.

Both products are excellent for baking because they add sweetness without adding calories or flavorings like vanilla extract or butter flavorings.

Liquid glucose and corn syrup also have high solubility in water, making them ideal for making meringues and other desserts that rely on whipping air into stiff peaks instead of using whipped cream (which is why whipped cream is more often used for frosting cakes).
