Abstract

|
|
|
An enzyme electrode for L-lactate measurements was prepared with an immobilized lactate oxidase fixed to an oxygen electrode. At optimal pH and temperature, this electrode was sensitive to 0.025 mM L-lactate. There is less than 4％ of the response for L-lactate in various interference such as D-lactate, malate, citrate, ascorbate, propionate, glutamate, aspartate, succinate, oxalate and acetate. This enzyme electrode was used for determination of L-lactate in various foods. The L-lactate comcentrations for kimchi, yogurt, soybean milk, wine and takju were 151.8-367.5, 323-411, 32.0, 120.4 and 63.7㎎/100㎖, respectively.
