Abstract
An amperometric biosensor for the determination of pectin was construc ted by combining orange peel tissue as a pectinesterase source with a carbon paste alcohol electrode using alcohol oxidase. A slice of orang e peel attached to the surface of the alcohol electrode deesterified p ectin, the methanol generated by the reaction was monitored by the ele ctrode. A linear response to pectin was observed in the concentration range of 0.1 to 0.9 g l(-1). No interference from other carbohydrates was observed.
