KS H ISO 5378-2008(2023) - Starches and derived products－Determination of nitrogen content by the Kjeldahl method

Introduction: The KS H ISO 5378-2008 (2023) standard, published by the Korea Agency for Technology and Standards (KATS), provides detailed guidelines on the determination of nitrogen content in starch and its products. This method is crucial for ensuring the quality control and consistency of these products within the food industry.

The standard specifies two primary methods: Kjeldahl Nitrogen Determination and Spectrophotometric Analysis. The Kjeldahl method involves digesting a sample with concentrated sulfuric acid, followed by distillation to release ammonia which is then absorbed in a receiving solution for titration. This process measures the nitrogen content accurately.

The spectrophotometric analysis, on the other hand, relies on the Beer-Lambert law to quantify the amount of nitrogen present based on absorbance measurements at specific wavelengths. Both methods are essential for maintaining high standards in food products and ensuring compliance with international regulations.
