This International Standard specifies a spectrophotometric method for the determination, by the Kjeldahl method, of the nitrogen content of starch and its derived products whose presumed nitrogen content is less than 0,025 % (m/m).
NOTE —In starches and their derived products to which nitrogen-ous materials have not been added, the nitrogen is present essen-tially in the form of protein and/or amino acids.
note:1) For products whose presumed nitrogen content is greater than 0,01 % (m/m), see ISO 3188.
