Abstract
The present disclosure disclosed is method for improving the transparency of starch liquefaction, and belongs to the field of biologically modified starch. The method changes the molecular structure of the starch liquefaction product by adding a 1,4-α-glucan branching enzyme from Rhodothermus obamensis, so the molecular structure has a smaller branched chain and a higher branching degree, thereby achieving the purpose of improving transparency and stability. The method comprises the steps of dissolving a starch liquefaction product in water according to a certain concentration to prepare an aqueous solution of the starch liquefaction product, and adding a 1,4-α-glucan branching enzyme to react at a certain temperature for a period of time, so as to improve the transparency of the starch liquefaction product during storage. The method provides a new idea for improving the stability of starch liquefaction products, and has great potential and application prospects.
