They are soluble in water. Natural sweeteners are prepared from natural materials, e.g., sugar from plants such as sugar-beet or sugar cane. Artificial sweeteners are designed by man, and usually prepared by a chemical process. They are designed to supply sweetness on its own, i.e., without the carbohydrate food values which are associated with sugar. They are used by consumers who may believe it disadvantageous to use sugars for sweetening foods and drinks.
Any surplus energy taken into the body as food is stored as fat.
Its most widespread members are sugars and starches. Its grain size is typically less than 0.3 mm in length, as against some 0.5 - 0.7mm for the usual granulated crystal. In the sugar industry, a centrifuge is a machine used to separate crystals of sugar from sugar syrups. The mixture of syrup and crystals is fed into a rapidly spinning cylinder with perforated walls. Centrifugal force causes the syrup to move outwards through the perforations, whilst the crystals are trapped inside the cylinder and can thus be separated and dried.
