What Is Inverted Sugar?
Inverted sugar, also known as invert sugar syrup or simply invert sugar, is a liquid sweetener derived from granulated table sugar and water. Table sugar, scientifically known as sucrose, is made up of glucose and fructose molecules bonded together. Invert sugar is created through a process called hydrolysis, where sucrose is mixed with water and heated until the molecular bonds between glucose and fructose break apart. This results in a thick, sweet syrup that is composed of individual glucose and fructose molecules.
The main advantage of invert sugar over regular sugar is its ability to retain moisture and prevent sugar crystallization, making it an ideal ingredient for a variety of processed foods and beverages. It provides a smoother texture and enhances the mouthfeel of many products, from baked goods and confectionery items to ice cream and sorbets.
Despite its unique properties, invert sugar shares the same nutritional profile as table sugar and other added sweeteners. It’s important to be mindful of the amount of added sugars in your diet, including invert sugar, to maintain a balanced and healthy lifestyle. While it does offer some benefits for cooking and food processing, it should be consumed in moderation, just like any other sugar.
Production and Properties of Inverted Sugar
Making Invert Sugar
Invert sugar is created by hydrolyzing disaccharide sucrose into its two monosaccharide components, fructose and dextrose (glucose). To make invert sugar, a sucrose solution is typically subjected to a combination of water, heat, and acids like citric acid or cream of tartar. This process breaks the bonds between glucose and fructose, giving a solution of half free glucose and half free fructose, known as invert sugar syrup.
The inverted sugar syrup is formed by:
- Dissolving sugar in water
- Adding a small amount of an acid, such as citric acid or cream of tartar
- Boiling the mixture while maintaining a specific concentration
Physical and Chemical Properties
Invert sugar syrup has a thick, smooth texture, making it popular for culinary uses. The hydrolysis process has numerous benefits, including:
