Abstract
The present disclosure discloses a method for preparing short-clustered dextrin, and belongs to the field of bio-modified starch. The method includes: collaboratively modifying to-be-modified starch by adopting Ro-GBE and Gt-GBE. The present disclosure utilizes two starch branching enzymes from different microorganism sources to collaboratively modify corn starch. The Ro-GBE is firstly added for pretreatment, then the Gt-GBE is added. The Ro-GBE catalyzes the to-be-modified starch to form a chain segment structure which is more conducive to further utilization for the Gt-GBE, thin and long starch molecule is transformed into short-clustered structure under the catalysis of Gt-GBE, and thus the slow digestibility of modified products is more obvious. Further, by changing the addition amount of Ro-GBE, modification time and the state of to-be-modified starch, the synergistic effect between the two branching enzyme is promoted, and the branching degree is improved, thus the SDS content and the RS content are further improved.
