The invention relates to a method for preparing cassava polysaccharide iron. The method is to oxidize and degrade cassava starch with hydrogen oxide to obtain an applicable oligosaccharide solution, and then add ferric chloride and sodium hydroxide solution dropwise to perform a complex reaction to obtain cassava polysaccharide. The iron synthesis solution is then filtered to remove water-insoluble impurities to obtain cassava polysaccharide iron solution, which is then desalinated and concentrated by ultrafiltration membrane technology, spray dried or vacuum evaporated, dried and crushed, and finally cassava polysaccharide iron products are obtained. The present invention uses hydrogen peroxide to oxidize and degrade cassava starch to replace the previous acid or enzymatic degradation process, which not only can significantly reduce the generation of by-product glucose than the acid method, obtain a higher yield of applicable oligosaccharides, and is more efficient than the enzymatic method. The degradation time is greatly shortened, thereby reducing production costs; it also replaces the previous ethanol or methanol solvent method to remove sodium chloride, avoids the use of flammable and explosive materials such as ethanol or methanol, and eliminates hidden dangers in production safety. The cassava polysaccharide iron prepared by the invention can be used as an iron supplement for poultry and livestock.
