Abstract: An amperometric method utilizing an enzyme electrode was developed for the determination of the glucose content of instant coffee. The electrode was constructed by combining an oxygen electrode with a beta-D-glucose oxidase-immobilized collagen membrane. Samples of instant coffee were analysed and the results obtained by the proposed method and by the established AOAC method agreed well (r = 0.9964). The sensor was stable for more than 2 weeks and for 320 analyses.
