White sugar, containing more than 99.7% of sucrose, is industrially obtained from two plants: sugar cane and sugar beet.
The first plant grows in tropical and sub tropical zones and is normally processed in two steps. In the first step a granular yellow sugar is obtained, named raw sugar, in Sugar Mills. In a second step, named refining, the final product, white sugar, is produced.
Sugar beet grows in temperate zones and white sugar is obtained in only one set of operations in Beet Sugar Factories.
