Ascorbic acid is added to fruit juices to restore nutritional values lost during processing. It helps maintain the color of the product and ensures stability thanks to its antioxidant properties.

CDR DrinkLab

Test type: End Point.
Testing time: [uni].
Analysis sessions with multiple samples are possible up to a maximum of 4 tests for CDR DrinkLab.

Method

Degas using the ultrasonic bath (code 222062) before taking the sample.

Sample treatment

Ascorbic acid is brought into contact with a colored complex in an alcoholic solution and oxidizes, decolorizing the complex. The decolorization, measured at 520 nm (end-point), is directly proportional to the concentration of ascorbic acid in the sample. The result is expressed in ppm.

Principle of the test

The calibration curve of the CDR DrinkLab system, carried out using HPLC as a reference method, confirmed excellent linearity of the system throughout the measurement range.
