Provided is a method for producing branched dextrin, the method comprising steps of: adding heat-resistant alpha-amylase to a starch suspension, heating the mixture at 85° C. to 115° C. to perform a liquefaction reaction, immediately heating the mixture at 125° C. to 145° C. to inactivate the heat-resistant alpha-amylase, and obtaining a liquefied starch solution including liquefied starch having a dextrose equivalent (DE) value of 2 to 10, and adding a branching enzyme to the liquefied starch solution in an amount of 0.6% (w/w) or more based on the dry weight of starch, proceeding with a branching reaction for 20 hour or more to generate branched dextrin, and then obtaining a solution with branched dextrin comprising branched dextrin having a dextrose equivalent (DE) value of 2 to 10 which stably controls the dextrose equivalent (DE) value of branched dextrin, and significantly suppresses the white turbidity that occurs during refrigeration.

Method for producing branched dextrin with improved white turbidity

The present invention provides a novel allulose epimerase variant in which an amino acid residue present at a specific position of an amino acid sequence of wild-type D-allulose 3-epimerase derived fromis substituted with another amino acid residue, and various uses thereof. The novel allulose epimerase variant according to the present invention has a higher conversion activity of fructose to allulose than that of the wild-type D-allulose 3-epimerase derived fromor a D-allulose epimerase variant W29K/G216S/M234I, and has excellent thermal stability especially under high temperature conditions of 60° C. or higher, thereby preventing contamination during an industrial-scale enzymatic conversion reaction for the mass production of allulose, shortening the production time, and reducing the production costs.
