The present invention relates to a method for producing trehalose, comprising the steps of mixing and reacting, in any order, (i) at least one alpha-phosphorylase capable of catalyzing the production of alpha-D-glucose 1-phosphate intermediate from a saccharide raw material, and from at least one phosphorus source; (ii) at least one trehalose phosphorylase capable of catalyzing the production of trehalose from an alpha-D-glucose 1-phosphate intermediate and a glucose substrate, wherein the trehalose phosphorylase is a trehalose phosphorylase variant with an amino acid sequence which differs from the amino acid sequence of a wild type trehalose phosphorylase in at least one amino acid position, (iii) at least one saccharide raw material which produces an alpha-D-glucose 1-phosphate intermediate and a co-product by catalytic action of the alpha-phosphorylase; and (iv) at least one phosphorus source selected from the group consisting of a phosphoric acids and an inorganic salt thereof.
