Abstract A process for synthesizing the ferrous salt of amino acid includes putting soybean dregs in 20-40% solution of sulfuric acid, heating and refluxing for 5-8 hrs, filtering to obtain free amino acid solution, using NaOH (4 mol/L) to regulate pH value to 7-9, adding 20% FeSO4.7H2O, boiling water bath for 1 hr to obtain the aqueous solution of target product, deposition by means of Ca(OH)2, centrifugal separation of superconant at 3000-5000 rpm for 20-50 min, and drying deposit. Said product can be used to supplement iron to human body.
