Abstract
A process for producing trehalose from inexpensive saccharide raw materials via an enzymic method uses stable enzymes with high productivity. The process includes incubating a saccharide raw material and an inorganic phosphoric acid and/or a salt thereof in the presence of phosphorylase to produce .alpha.-glucose 1-phosphate, and contacting the produced .alpha.-glucose 1-phosphate with glucose in the presence of a trehalose phosphorylase to produce trehalose. The isolation and purification of trehalose is easier in comparison to conventional fermentation methods.
