Amperometric enzyme-based biosensors for application in food and beverage industry
Bioanalytik, Göttingen, Germany [9 1]) and their characteristics were evaluated and
compared with those obtained using reagentless biosensors developed in our
laboratories (see section 4.3).
As seen from the figure 10 the used sequential-injection analyser with integrated
biosensors was able to follow the decrease of glucose and simultaneous increase of the
ethanol concentration in the expected way.

wine (see text for more details)
6. Conclusions
Many integrated biosensors fulfil the requirements for their analytical applications in
food and beverage industry. Their bioelectrochemical characteristics (sensitivity,
selectivity, and stability) combined with their simplicity in use and relative cheapness
forecast a wide spread of these analytical tools in the field of production and control of
various foodstuff and beverages.
