Businesses in the manufacture of sugar process sugar-bearing crops or raw sugar into products for food production, retail and other industrial uses. In the UK, sugar is commonly extracted from sugar beet: the roots are washed, sliced and soaked to dissolve the sugar, and the resulting juice is purified, concentrated and crystallised. Some manufacturers also refine imported raw cane sugar, removing impurities and producing crystals to specified grades. Typical products include granulated, caster and icing sugar, as well as different crystal sizes and degrees of refinement for baking, confectionery, drinks and food processing. Manufacturers may also produce liquid sugar, syrups and specialist sugars for commercial customers. Processing can generate co-products such as molasses and beet pulp, which may be used in food, fermentation or animal feed. Businesses in this category generally operate processing plants and may supply ingredients in bulk or packaged formats.
