AI Summary AI generated
This standard specifies technical requirements and test methods for zinc lactate as a food nutritional fortification substance. Zinc lactate is produced from lactic acid and zinc oxide or zinc carbonate, with formula C6H10O6Zn·nH2O. It requires a minimum content of 98.0% and sets limits for loss on drying, pH, lead, arsenic, and cadmium. Annexes provide detailed test methods including titration for content and HPLC for isomer ratio determination.
本标准规定了食品营养强化剂乳酸锌的技术要求、检验方法等。乳酸锌由乳酸与氧化锌或碳酸锌反应制得，分子式为C6H10O6Zn·nH2O。标准要求乳酸锌含量不低于98.0%，并规定了干燥减量、pH值、铅、砷、镉等限量指标。附录提供了详细的检验方法，包括滴定法测定含量、高效液相色谱法测定乳酸锌与异构体比例等。
