Provided is a method of preparing ferric carboxymaltose with weight average molecular weight between 100,000 and 400,000. The method includes reacting an oxidized maltodextrin solid with an iron (III) salt solution in acidic and basic conditions in sequence to afford ferric carboxymaltose, wherein the oxidized maltodextrin solid has a dextrose equivalent of less than 4. The ferric carboxymaltose prepared by the method can withstand high-temperature sterilization with high stability and facilitate storage.

The present invention provides a method for producing dietary fiber that has a mild sweet taste by reducing sugars and provides by-products having high added values, and dietary fiber produced by the method. The dietary fiber may be produced by including: liquefying roasted dextrin; and adding enzymes including α-amylase, β-amylase, and maltogenic amylase to the liquefied roasted dextrin, and saccharifying the same.

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.
