The basic raw material for sugar production in temperate zones of the north is sugar beet. It is a plant in whose spindle shaped root sugar and numerous other compounds are stored and their shares, as well as their ratio, depend mostly on chemical composition of the soil and fertilisation. Samples of sugar beet, together with samples of all intermedial products in technological process of sugar production (raw juice, thin juice, thick juice, massecuite A, green syrup "A", white syrup "A", massecuite B, green syrup "B", white syrup "B", "B" sugar, standard liquor, "C" sugar, molasses, afinated "C" sugar and afinated "C" syrup) along with samples of final product, crystalline sugar, were taken and their process parameters: dry matter content, polarisation, purity quotient, pH-value, invert sugar content, color, and also, Silin number, Swedish number and crumbs were measured in order to define quality of those samples. The results showed that the crystalline sugar, a product of 2005. sugar campaign, was of satisfactory quality, equal to that in sugar beet, whose quality was as same as the average for the past ten years.
