eng	Amperometric tyrosinase carbon paste-based biosensor in food analysis	Carbon paste electrodes with surface modification by carbon nanotubes was chosen as an electric transducer, on which tyrosinase was immobilized using conductive copolymer Nafion to develop a final biological sensor. Commonly used spectrophotometric methods based on reducing properties of analyzed polyphenols can be replaced by this more sensitive electrochemical sensor. The biosensor was applied in analyses of food with low content of vitamin C such as wines, beers, teas, selected fruits, etc.	carbon paste electrode; polyphenols; tyrosinase biosensor; food analysis
