To make sugar, machines are used: sugar cane (or sugar beet) is initially pressed and the juice is then mixed with lime to achieve the desired ph balance and to help settle out impurities. Reduction of this solution through evaporation produces a solid mass that is passed through centrifuge to get sugar crystals. It is then dried further to produce granules. This sugar is light brown in color and is termed raw sugar. The brown color of raw sugar is due to presence of molasses. Raw sugar is the most natural sugar you can hope to lay your hands on.
