　　【化工仪器网政策标准】近日，根据《食品安全法》及其实施条例规定，食品安全国家标准审评委员会组织起草了《食品安全国家标准柠檬酸锰》、《食品安全国家标准氯化铬》、《食品安全国家标准 L-抗坏血酸钾》3项食品安全国家标准(征求意见稿)，现面向全社会公开征求意见。有意见的业内人士请于2020年6月6日前登录食品安全国家标准管理信息系统在线提交反馈意见。

　　《食品安全国家标准柠檬酸锰》的制定主要参考了美国食品化学法典(FCC 9)中柠檬酸锰的技术指标及参数，适用于以柠檬酸与硫酸锰、碳酸锰为主要原料，经化学反应制得的食品营养强化剂柠檬酸锰。

　　标准的主要技术内容包括鉴别实验、柠檬酸锰的含量、干燥失重、砷和铅、硫酸盐。检测用的试剂和材料包括盐酸溶液、硫化铵溶液、冰乙酸、吡啶、醋酸酐，使用的仪器和设备有分析天平。柠檬酸锰含量测定的方法为：在pH为10的氨-氯化铵缓冲溶液中，以铬黑T为指示剂，用乙二胺四乙酸二钠标准溶液滴定试样溶液，根据乙二胺四乙酸二钠标准滴定溶液的用量，计算以Mn3(C6H5O7)2计的柠檬酸锰的含量。

　　需要注意的是，本标准试验方法中使用的部分试剂具有毒性或腐蚀性，使用时需小心谨慎并按相关规定操作。若溅到皮肤上应立即用水冲洗，严重者应立即治疗。在使用挥发性酸时，应在通风橱中进行。

　　《食品安全国家标准氯化铬》的制定主要参照 FCC10、美国药典(USP 40)、韩国食品添加剂法典(2016)、HG/T 4311-2012，结合国内企业生产实际情况制定。该标准指定的指标有：感官指标(色泽、状态)、主含量、水不溶物、氨水溶解物、硫酸盐、铁、总砷、镉、铅、总汞，以及氯化铬的鉴别，适用于以三氧化铬及盐酸为原料进行反应，经还原制得的食品营养强化剂氯化铬。

　　测定氯化铬含量需要使用试剂和材料有过氧化氢溶液、过氧化氢、硫酸溶液、淀粉指示剂，使用的仪器设备有电子天平、电炉。需要注意的是，标准所用试剂和水，除特别说明，均指分析纯试剂和GB/T 6682中规定的三级水及以上试验用水。试验中所用标准溶液、杂质标准溶液、制剂及制品，在没有注明其他要求时，均按GB/T 601、GB/T 602、GB/T 603的规定制备。试验中所用溶液在未注明用何种溶剂配置时，均指水溶液。

　　《食品安全国家标准 L-抗坏血酸钾》的范围、分子式、结构式和相对分子质量、感官指标、理化指标及检测方法等部分均根据产品的实际生产工艺、化合物特有性质、检测及验证数据而制定，与现有资料结论保持一致，并经行业内广泛征求意见，兼顾科学性和实用性而确定。其中相关安全指标如铅、砷的设定，在进行污染物暴露评估保证安全的基础上，结合样品检测数据，参考《抗坏血酸棕榈酸酯》(GB 1886.230-2016)及《碳酸氢钾》(GB 1886.247-2016)，分别定为 2.0 mg/kg、3.0 mg/kg。

　　该项新标准适用于以 L-抗坏血酸和碳酸氢钾或碳酸钾为原料，经化学反应、结晶、干燥等工艺制得的食品营养强化剂 L-抗坏血酸钾。测定L-抗坏血酸钾含量需要的试剂和材料包括五氧化二磷、硫酸溶液、碘标准滴定溶液、淀粉指示液。分析步骤为：称取用五氧化二磷干燥24 h的试样约0.2 g，精确至0.0001 g，用100mL新沸的冷蒸馏水和15 mL硫酸溶液，使其溶解，立即用0.1 mol/L碘标准滴定溶液滴定，接近终点时加2 mL淀粉指示液，继续滴定至溶液呈蓝色，在30s内不褪色为止，记下碘标准滴定溶液消耗的毫升数。
