What is sugar made of?

White sugar is made from sucrose or beet sugar extracted from sugarcane or beetroot by refining and decoloring.

In order to make white sugar, sugarcane or beetroot should be squeezed and crushed to get juice. Fruit juice contains a lot of sucrose or beet sugar. Fruit juice is purified by filtration, precipitation and other purification processes to remove impurities and impurities. The purified syrup is heated and continuously stirred, so that the water in it gradually evaporates and the sugar in the syrup is concentrated.

When the sugar concentration in the syrup reaches a certain level, the syrup is cooled and the sugar begins to crystallize. The crystallized sugar cake is large and needs to be crushed and sieved. In order to make the color of sugar whiter, decoloration will be carried out. Usually, activated carbon, ion exchange resin and other substances are used to decolorize sugar. The decolorized syrup is heated again and filtered to remove impurities and impurities, and pure syrup is obtained.
