Glucose syrup is a popular substitute for sugar. It is more commonly referred to as corn syrup because its main ingredient is usually cornstarch. From a strictly chemical perspective, it is any liquid starch consisting of carbohydrates. In addition to cornstarch, it can be made from any form of starch, including wheat, rice or potatoes.
Because of its successful and easy bonding with dry or solid substances, this syrup is the preferred sweetener for candy, chewing gum, jams, jellies and canned fruit. The main benefit of this syrup over regular granulated sugar is its non-crystallizing properties. It is also praised for its preservative qualities.
