ZOSSI, B. Silvia et al. Comparing two methodologies to determine starch in sugar. Rev. ind. agríc. Tucumán [online]. 2008, vol.85, n.2, pp.9-16. ISSN 1851-3018.

Because of the great importance starch has during sugar processing, a new and quick methodology was validated to determine starch in sugar before its comparison with the technique employed in the lab. This method was developed by SPRI and is based on starch-iodide complex colorimetric detection. Detection and quantification limits, linearity, bias and uncertainty were determined. The results showed that this method is acceptable to determine starch in different kinds of sugar at levels between 33 and 2667 mg/kg, with an uncertainty of ± 6,18 mg/kg. This methodology was compared with COPERSUCAR technique, and although both methods are statistically different, a high correlation between them exists.
