Overview of Corn Syrup

Corn syrup is a sweetener derived from the starch of corn. Its primary component is glucose, but it also contains varying amounts of maltose and higher oligosaccharides, depending on the grade.

This syrup serves as an essential ingredient in the food industry, notably for its sweetening properties.


  • Glucose: Predominant sugar in corn syrup
  • Fructose: Can be added to make high-fructose corn syrup (HFCS)

Uses in Foods:

  • Sweetening agent in beverages and baked goods
  • Binding agent in cereal and granola

Unlike table sugar, which contains both glucose and fructose, pure corn syrup is primarily glucose.

You might sometimes hear about high-fructose corn syrup (HFCS), which is corn syrup that has undergone enzymatic processing to convert some of the glucose into fructose.

HFCS is often compared to sucrose (table sugar) in sweetness and is used in a similar way.

Sweetness & Texture:

  • Contributes to the sweet taste desired in many cereals and snacks
  • Helps provide the ideal texture, such as chewiness in granola bars

When it comes to blood sugar levels, your body reacts to different sweeteners based on their glycemic index.

Pure corn syrup has a high glycemic index compared to fructose, which means it can raise your blood sugar rapidly.

Health Implications:
The consumption of sweeteners, including corn syrup, should be done judiciously as excessive intake can lead to health concerns, such as weight gain and an increased risk of type 2 diabetes.

It’s important to balance your diet with foods low on the glycemic index for better blood sugar level management.
