ABSTRACT:
A method and device (10) for removing oxygen using a reduced oxidase enzyme and for providing a calorimetrically detectable signal of the presence of the oxygen. A reduced laccase or ascorbate oxidase is preferably provided with a substrate which reduces the oxidase. Color is generated which can be detected visually or by other means such as a spectrophotometer. The method and device are particularly useful in the food, pharmaceutical and biological industries.
