Abstract
A saccharide composition containing trehalulose, which is obtainable by allowing a maltose/trehalose converting enzyme to act on a sucrose solution to produce trehalulose, and collecting the resulting trehalulose-containing mixture. Since the enzyme converts sucrose into trehalulose in a relatively high yield and the conversion rate is controllable, a saccharide composition rich in trehalulose is readily obtained on an industrial scale.
Claims Summary
1. A process for producing a saccharide composition containing trehalulose, which comprises allowing a maltose/trehalose converting enzyme to act on a sucrose solution under conditions sufficient to produce said trehalulose, and collecting the resulting trehalulose-containing mixture.
