Quality control during refining sugar from sugar beet and raw brown sugar from sugar cane

Production and consumption of sugar is increasingly growing and today it totals around 150 million tons per year. Sugar on the market is mostly produced from sugar beet and sugar cane. Quality control during sugar production is crucial, since it enables production of high quality sugar. The aim of this research was to conduct analyses of raw materials, semi-products and final products in the production of sugar from sugar beet and raw sugar from sugar cane. In addition, results of analyses conducted during sugar production from different raw materials (sugar beet and sugar cane) were compared. During production of sugar from sugar beet, analyses were conducted at the beginning of the campaign and every month during campaign, while during production of sugar from sugar cane analyses were conducted every week during one month period. Results showed that sucrose content decreased towards the end of campaign. Concentration, polarisation, purity and pH values were similar for afinated sugar from sugar beet and afinated sugar from brown cane sugar. Molasses from sugar cane had higher purity compared to molasses from sugar beet. Quality analysis of consumption sugar showed that sugar was produced in accordance with quality requirements.
