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.
