* ASTM Starch Content analysis is designed to meet the following definition of Starch as per ASTM WK63392: starch, n – a polysaccharide consisting of glucose monomers joined in α 1,4 linkages; the simplest form of starch is the linear polymer amylose while amylopectin is the branched form. Starch by this definition shall include the soluble C6 glucan mono- and oligosaccharides. Since the EPA definition for “cellulosic content” is specific to the “sum of cellulose, hemicellulose, and lignin in cellulosic feedstock”, the soluble C6 glucan mono- and oligosaccharides shall be included with the starch total. Since the only difference between starch and cellulose is the orientation of the 1, 4 linkage, to determine the starch content of a sample that contains both starch and cellulose an assay that utilizes amyloglucosidase is necessary.

** ASTM Cellulosic Content analysis is designed to meet the following definition of Cellulose Content as per ASTM WK63392: cellulosic content, n – as defined by EPA RFS documentation: the sum of cellulose, hemicellulose, and lignin in cellulosic feedstock.
