Co-determination of sodium metabisulfite and starch in corn syrup by flow injection coulometry.


During the processing of corn syrup for commercial use, starch, in the form of alpha -amylose, must be completely broken down to its D -glucopyranose units. Sodium metabisulfite is added to the corn syrup as a preservative. Flow Injection Coulometry was used to perform an automated assay of these analytes, both individually and jointly. The sodium… (More)
