The invention relates to the technical field of maltose manufacturing, in particular to a maltose syrup purification method which comprises the following steps: S1, adding a syrup stock solution and deionized water into a reaction kettle, uniformly stirring, adding an acidifying agent, sterilizing to obtain a syrup solution, pumping the syrup solution into a nanofiltration circulating tank, and carrying out nanofiltration treatment to obtain a nanofiltration solution; when the volume of the solution in the nanofiltration circulating tank is reduced to 7/25 of the volume of the pumped syrup solution, pure water is added into the concentrated solution, so that the volume of the solution in the nanofiltration circulating tank is increased to be equal to the volume of the pumped syrup solution, nanofiltration treatment continues to be carried out, the steps are repeated 3-4 times, and a concentrated syrup solution is obtained; the method can effectively solve the problem that the preparation of the ultrahigh malt
