The disclosure discloses a method for producing maltodextrin with a single polymerization degree by multienzyme coupling, and belongs to the technical field of biology. The disclosure provides a method for producing non-reducing maltodextrin with a uniform and low polymerization degree. After a reaction is preformed for 2-6 hours by using the method of the disclosure, the content of 4-O-α-maltohexaosyl α-D-glucoside in a reaction solution can be as high as 57.2% to 77.3%, accounting for 50% to 90% of the total amount of maltodextrin in the reaction solution. In maltodextrin prepared by using the method of the disclosure, non-reducing maltodextrin with low polymerization degree only includes 4-O-α-maltohexaosyl α-D-glucoside, and the content of non-reducing maltodextrin with low polymerization degree can be 50% to 90% of the total amount of maltodextrin. Therefore, only filtration is needed in preparation of non-reducing maltodextrin with low polymerization degree by using the method of the disclosure; additional separation and purification steps are not needed; high-purity non-reducing maltodextrin with low polymerization degree can be obtained; and the production cost is low.
