Abstract

Provided is a method for improving the production amount of a tri- or higher galactooligosaccharide and the reaction rate by a method for producing a galactooligosaccharide characterized by allowing β-galactosidase to react with a substrate in the presence of 5 to 60 mM sodium ions and 0.5 to 8 mM magnesium ions.

Claims

exact text as granted — not AI-modified

1 . A method for producing a galactooligosaccharide, characterized by allowing β-galactosidase to react with a substrate in the presence of 5 to 60 mM sodium ions and 0.5 to 8 mM magnesium ions. 
     
     
         2 . The production method according to  claim 1 , wherein the concentration of magnesium ions is from 1.5 to 8 mM. 
     
     
         3 . The production method according to  claim 1 , wherein β-galactosidase is derived from a microorganism belonging to the genus  Kluyveromyces.
