ES2728448
Device and method for measuring ascorbic acid and anthocyanins in juices. A device and method for measuring ascorbic acid and anthocyanins in juices comprising an amperometric sensor (1) comprising a first working electrode (3) and a second working electrode (4); electronic means for capturing and processing data (6, 7, 8, 9); a graphic management and/or configuration interface (10); and where the first working electrode (3) is not treated with ascorbate oxidase and a second working electrode (4) that is treated with ascorbate oxidase; and where the electronic means (6, 7, 8, 9) are configured to stimulate the sensor (1) according to a predefined range of voltages depending on the type of juice selected by a user in the graphic management interface and/or configuration (10), and simultaneously obtain the current reading due to the oxidation of the juice studied.

The system simultaneously carries out the determination of ascorbic acid and anthocyanins, using a dual printed carbon electrode formed by two working electrodes in the same analysis. It allows sample measurements to be carried out with a periodicity and economic amount appropriate for industrial demands. Advantages: -Low cost per measurement and determination device. -Portability. -Ease of use and reduced determination time. -No sample processing required. -Measures several substances of interest using a single analysis.
