Invert sugar

Invert sugar is a type of sugar that has been chemically processed to split its sucrose molecules into glucose and fructose. This process, known as inversion, results in a sugar that is sweeter than regular table sugar and has different physical and chemical properties. Invert sugar is commonly used in baking and confectionery due to its ability to retain moisture and prevent crystallization.

History

The process of inverting sugar was first discovered in the 19th century. It was initially used in the brewing industry, but quickly found applications in other areas of food production.

Production

Invert sugar is produced by adding a small amount of acid to a sucrose solution and heating it. The acid, usually citric acid or tartaric acid, catalyzes the inversion process. The resulting solution is then neutralized with an alkali to remove the acid.

Properties

Invert sugar is sweeter than regular sugar due to the presence of fructose, which is sweeter than both glucose and sucrose. It also has a lower freezing point and a higher boiling point than sucrose, making it useful in certain cooking applications.

Invert sugar is hygroscopic, meaning it attracts and retains moisture. This makes it useful in baking, as it can help to keep baked goods moist and extend their shelf life. It also prevents crystallization, which can be beneficial in the production of smooth, creamy confections like fudge and caramel.

Uses

Invert sugar is used in a variety of food applications. It is commonly used in baking, confectionery, and ice cream production. It is also used in the brewing industry, as it is easily fermentable and can contribute to the alcohol content of beer.

Health effects

Like all sugars, invert sugar contributes to calorie intake and can contribute to weight gain if consumed in excess. However, it is no more harmful than other types of sugar when consumed in moderation.
