Why is corn syrup used in food?
Corn syrup, also known as glucose syrup to confectioners, is used in foods to soften texture, add volume, prevent crystallization of sugar, and enhance flavor. The more general term glucose syrup is often used synonymously with corn syrup, since glucose syrup in the United States is most commonly made from corn starch.
Why has the use of corn syrup as a sweetener become so common?
Similarly to regular table sugar (sucrose), it’s composed of both fructose and glucose. It became a popular sweetener in the late 1970s when the price of regular sugar was high, while corn prices were low due to government subsidies (1).
How is corn syrup processed?
Corn syrups are produced from refined corn starch by subjecting the wet starch to acid or enzymatic hydrolysis, which convert the starch to dextrose, maltose, and dextrins.

What is the problem with corn syrup?
It is known, however, that too much added sugar of all kinds — not just high-fructose corn syrup — can contribute unwanted calories that are linked to health problems, such as weight gain, type 2 diabetes, metabolic syndrome and high triglyceride levels. All of these boost your risk of heart disease.
Is corn syrup healthier than sugar?
Thus, sugar and high-fructose corn syrup are exactly the same from a health perspective. Many studies show that sugar and high-fructose corn syrup have similar effects on health and metabolism. Both are harmful when consumed in excess.
How bad is corn syrup?
Is corn syrup a pure substance or mixture?
Mixtures contain more than one kind of matter. For example, cola is a mixture that can be separated into carbonated water, corn syrup, caramel color, phosphoric acid, natural flavors, and caffeine. Homogeneous mixture is the same throughout A homogeneous mixture is the same throughout.
Why do people still eat foods high in fructose corn syrup?
Here are a few reasons people continue to consume foods high in fructose corn syrup. High fructose corn syrup is derived from cheap industrial corn, an abundant crop in America. You can find this ingredient in every aisle of the grocery store. Every item of a fast food meal is also likely to contain HFCS.
Why are enzymes added to corn syrup to make it sweet?
Enzymes are added to corn syrup to change the glucose into another simple sugar. This simple sugar is called fructose. The enzymes have been genetically modified to improve their heat stability. This makes the production of high fructose corn syrup easier. This sweetener is often compared to table sugar.
How are HFCS different from sucrose and other sweeteners?
In sucrose, a chemical bond joins the glucose and fructose. Once one eats, stomach acid and gut enzymes rapidly break down this chemical bond. In HFCS, no chemical bond joins the glucose and fructose. Other nutritive sweeteners can vary in their fructose content (by “nutritive,” we mean that the sweetener contains calories).
What happens when corn starch is broken down?
When corn starch is broken down into individual glucose molecules, the end product is corn syrup, which is essentially 100\% glucose. To make HFCS, enzymes are added to corn syrup in order to convert some of the glucose to another simple sugar called fructose, also called “fruit sugar” because it occurs naturally in fruits and berries.
