GB/T 46001-2025 is the Chinese national standard covering the commercial soy isoflavone powder sold as a food ingredient rather than as a health food — the terms that cover daidzin, genistin, glycitin and their aglycones, the quality indicators of Table 1, the isoflavone content measured by high performance liquid chromatography, the moisture, ash, colour, odour and fineness, the net content check, the inspection rules, and the labelling, packing, storage and transport.
