Abstract
An enzyme electrode for measuring malto-oligosaccharides having a co-immobilized enzyme membrane containing glucoamylase and a glucose oxidizing enzyme such as glucose oxidase or pyranose oxidase. The glucoamylase and glucose oxidizing enzyme are immobilized at a ratio of ##EQU1## where Va is the maximum reaction rate of glucoamylase as expressed in the glucose formation rate from maltose, and Vo is the maximum reaction rate of glucose oxidizing enzyme as expressed in the hydrogen peroxide formation rate from glucose. In such enzyme electrode, malto-oligosaccharides are detected at the response value proportional to their degree of polymerization. Therefore, the malto-oligosaccharides can be measured at the glucose converted concentration.
