Difference Between White Sugar and Raw Sugar

White Sugar vs Raw Sugar

Despite sugar being one of the most important and commonly used items in a kitchen, most people are not aware of the fact that apart from the white sugar they use, there is another variety of sugar, called raw sugar, available in the market. Even those who know and use raw sugar are not pretty sure of the differences between white sugar and raw sugar. Let us take a closer look at these two different types of sugars.

White sugar or table sugar as it is called is pure sucrose that is a source of carbohydrate and is naturally found in many fruits and vegetables. In nature, it is found in greatest quantities in sugarcane plants and sugarcane beets from which it is separated to convert into the form that we use. White sugar is refined sugar that is prepared from natural sugar, or raw sugar as it is referred to. So before moving on to white sugar, let us se how raw sugar is manufactured.

Machines are used to press and crush sugarcane plants to extract the juices. Lime is added to this juice to attain the required pH level and to remove any impurities that may be present in the juice. Reduction of this solution through evaporation produces a solid mass that is passed through centrifuge to get sugar crystals. This sugar is light brown in color and is termed raw sugar. This is also the most natural sugar you can hope to lay your hands on.

To make white sugar, sulfur dioxide is added to cane juice before it gets evaporated. This gas does the bleaching of the juice so that it does not turn brown and produces white sugar. At later stages, phosphoric acid, calcium hydroxide or carbon dioxide is added to absorb impurities. This juice is then filtered through a bed of carbon and then crystallized in a vacuum many times. Finally the crystals are left to dry on their own to get paper white crystals of sugar.

What is difference between White Sugar and Raw Sugar?

• Now that we know the production processes of both raw sugar and white sugar, it becomes clear that while raw sugar is natural, there are way too many additives, acids and preservatives added to make white sugar.

• Because of the presence of molasses in raw sugar, it has a distinct flavor that is missing in white sugar.

• Calorific value of raw sugar is just 11kcal per teaspoon whereas it is much higher (16kcal) in the case if white sugar
