ASBC Methods of Analysis - Beer-41: Total Carbohydrate
ASBC Methods of Analysis
These methods are designed to measure the carbohydrate in beer. In Beer-41A, dextrin, the primary carbohydrate present in beer, is hydrolyzed to dextrose by sulfuric acid. Dextrose and phenol, in the presence of sulfuric acid, react further to produce a colored complex that is measured spectrophotometrically. Beer-41B measures the carbohydrate content of beer by high-performance liquid chromatography. Samples are subjected to an ionexchange resin, filtered, and then chromatographed.
