  • Method for producing maltodextrin with single polymerization degree by multienzyme coupling
    Patent number: 12203119
    Abstract: 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-?-maltohexaosyl ?-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-?-maltohexaosyl ?-D-glucoside, and the content of non-reducing maltodextrin with low polymerization degree can be 50% to 90% of the total amount of maltodextrin.
