ABSTRACT:
A disposable test strip device for detecting and measuring ethanol in aqueous solutions is disclosed. The test strip includes an inert support pad that contains a stabilized dry form of the enzyme alcohol oxidase, a material having peroxidative activity and an oxygen acceptor that reacts with hydrogen peroxide to give a compound of changed color. The use of this strip to determine ethanol levels colorimetrically is also disclosed. The stabilizer can comprise a solid aliphatic polyhydroxy compound of from 5-8 carbons and 5-7 hydroxyl groups.
