(57) [Summary] [Object] To provide an industrially advantageous method for producing α, α-trehalose from α-glucan such as starch, which is an inexpensive raw material, by combining α-glucan phosphorylase and trehalose phosphorylase. . [Structure] α, α-comprising a reaction (A) in which α-glucan phosphorylase acts on α-glucan and phosphate, and a reaction (B) in which trehalose phosphorylase acts on α-glucose-1-phosphate and glucose Method for producing trehalose. |
