CDR DrinkLab is a quick, reliable and easy analysis system for the quality and process control of the beverage sector

Determination of Caffeine in Soft Drinks

Measuring caffeine in soft drinks, particularly in energy drinks, is essential to ensure safety, compliance, and product quality control. High doses of caffeine, typical of these beverages, can have significant physiological effects.

CDR DrinkLab enables precise quantification of caffeine content, supporting both accurate product labeling and compliance with current regulations.

Method

Sample treatment

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

Principle of the test

Caffeine is extracted from the beverage through an appropriate solvent. After centrifugation, the extract is measured spectrophotometrically and the absorbance of the sample is correlated to the concentration of caffeine.

Calibration curve

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.
