Lotus root starch capable of strengthening homologous polyphenol and making method of lotus root starch

The invention discloses lotus root starch capable of strengthening homologous polyphenol and a making method of the lotus root starch. The polyphenol is from homologous solid waste of nelumbo nucifera, including lotus rhizome nodes, lotus root skin, receptaculum nelumbinis and lotus seed shells. A preparation process of the lotus root starch comprises the following technologies of pretreating lotus roots, performing grinding to obtain pulp, performing dehydration, performing precipitation, performing drying for the first time, blending polyphenols substances, performing stirring, performing granulation, performing drying for the second time, performing packaging and the like. The qualified lotus root starch dissolves after being put into mouths, the moisture content is 5-7.5%, and the polyphenol content is 0.5%-5%. The production process is clean, environmental-friendly, simple in technology and easy in industrial production. 本发明公开种强化同源多酚的藕粉及其制备方法，其多酚来源于莲的同源固体废弃物-藕节、藕皮、莲房和莲子壳。其藕粉制备过程包括莲藕预处理、磨浆、脱水、沉淀、初次干燥、多酚类物
