Sugar
Sugar cane needs a climate with no frost, with enough rain in the growing season so that the plant grows. It is harvested by a machine or by hand, and cut into pieces and is moved to the processing plant where it is milled. The juice is extracted with water or it is extracted by diffusion. The juice is clarified with lime and heated to destroy enzymes. The thin syrup result is concentrated in evaporators, after then water is removed. The supersaturated solution is added with sugar crystals, making crystals and drying easier. Molasses, fiber from the stems, is burned to give energy for the sugar extraction process. The raw sugar crystals have a sticky brown coating and may be bleached by sulfur dioxide, or may be treated in a carbonation process to make it whiter. About  of water is needed for every  of sugar to be produced.
