Abstract
Overview
EN ISO 10520:1998 specifies the Ewers polarimetric method for determining the starch content of native starches. This internationally recognized standard, issued by CEN and adopted from , focuses on the quantitative analysis of native starch excluding high-amylose starch, and is not applicable to modified or pregelatinized starches. The method applies polarimetric measurement of optical rotation after specific chemical treatments, offering precise, reproducible starch content results essential for quality control and research in food, biochemical, and industrial starch applications.
