Glucan manufacturing method. The first method includes a step of reacting a reaction solution containing sucrose, a primer, inorganic phosphate or glucose-1-phosphate, sucrose phosphorylase, and glucan phosphorylase to produce glucan, wherein The maximum value of the sucrose-phosphoric acid ratio of the reaction solution from to the end of the reaction is about 17 or less. The second method comprises reacting a reaction solution containing sucrose, a primer, inorganic phosphate or glucose-1-phosphate, sucrose phosphorylase, and glucan phosphorylase to produce glucan, wherein the reaction comprises At a temperature of from about 40C to about 70C. |
