KS H ISO 3188-2008(2023) - Starches and derived products－Determination of nitrogen content by the Kjeldahl method

Introduction: The KS H ISO 3188-2008 (2023) standard, developed by the Korea Agency for Technology and Standards (KR-KATS), provides detailed guidelines for determining nitrogen content in starch and its products through the Kjeldahl method. This analytical technique is widely recognized as a reliable way to measure protein content indirectly by quantifying nitrogen levels. The revised standard includes specific procedures for sample preparation, digestion of samples with sulfuric acid, distillation, absorption using boric acid solution, and titration with standard sodium hydroxide solution. It also outlines the necessary equipment, such as a Kjeldahl apparatus, condenser, receiver flask, and burette. The document emphasizes precision and accuracy in measurement to ensure consistency across various laboratories applying this method for quality control purposes.
