ZOSSI, B. Silvia et al. Validation of a methodology to determine starch in sugar. Rev. ind. agríc. Tucumán [online]. 2008, vol.85, n.2, pp.1-7. ISSN 1851-3018.

Starch is an undesirable microcomponent in sugar processing because of the problems it causes during this process and that of food production using sugar as raw material. For this reason, a reliable determination method is required. As the laboratory of Sección Química of Estación Experimental Agroindustrial "Obispo Colombres" (EEAOC) works under a quality system, a technique developed by Copersucar was validated. Detection and quantification limits, linearity, accuracy and uncertainty were determined. The results showed that this method is acceptable to determine starch concentrations in different sugar types at levels between 25 and 600 mg/kg. Uncertainty was ±10,8%.
