Note: Granulated sucrose consists of white free lowing granules of a crystalline appearance. White sugar is
reined from sugar beet or sugar cane in a complex continuous process, which involves cleaning, puriica-
tion, decolorization, concentration, crystallization, separation, drying and conditioning .
