Abstract
There is provided a dried L-glutamate oxidase composition containing an L-glutamate oxidase, which is stable even if it is stored for such a long term as one year or longer. The composition is a dried composition, preferably lyophilized product, containing an L-glutamate oxidase and a disaccharide. A preferred example of the disaccharide is lactose. Content of the disaccharide per 100 U of the L-glutamate oxidase is preferably 0.5 to 50 mg.

A dried L-glutamate oxidase composition, consisting of an L-glutamate oxidase and 0.5 to 50 mg of a disaccharide per 100 U of the L-glutamate oxidase.
A method for producing a dried L-glutamate oxidase composition which consists of an L-glutamate oxidase and a disaccharide, the method comprising:
- preparing an aqueous composition consisting of an L-glutamate oxidase and a disaccharide,
- dehydrating the prepared aqueous composition to obtain a dried composition,
- storing the dried composition for at least 4 weeks,
- and measuring an enzymatic activity of the stored composition.
