本发明公开了一种铁质食品营养强化剂乙二胺四乙酸铁钠的生产方法,包括原料合成溶解、浓缩、结晶、离心、干燥、粉碎筛分后和包装入库工序,其创新点在于:该生产方法以氧化铁、乙二胺四乙酸和钠盐为原料;所述原料合成溶解步骤为按照氧化铁、乙二胺四乙酸、钠盐的质量比为1:3.5~4.5:0.8~1的比例,向溶解锅中加入水后继续加入氧化铁和乙二胺四乙酸,加热至100℃,加入钠盐,待溶液完全溶解后调节溶液pH值至3.0~6.0。
The invention discloses a production method of a ferrous food nutrition fortifier iron sodium ethylenediaminetetraacetic acid, which comprises the steps of synthesizing, dissolving, concentrating, crystallizing, centrifuging, drying, crushing and screening the raw materials and packaging and warehousing. The innovation point lies in that: : The production method to iron oxide, ethylenediaminetetraacetic acid and sodium salt as raw material; the raw material synthesis and dissolution step is in accordance with the mass ratio of iron oxide, ethylenediaminetetraacetic acid, sodium salt is 1: 3.5 to 4.5: 0.8 ~ 1 ratio, adding water to the dissolving pot, adding ferric oxide and ethylenediaminetetraacetic acid continuously, heating to 100 DEG C, adding sodium salt, and adjusting the solution pH to 3.0-6.0 after the solution is completely dissolved.
