Caffeine determination

Determination of caffeine from food and dietary supplements with an HPLC-UV-VIS method.

According to Regulation (EU) No 1169/2011 on the provision of food information to consumers, caffeine-containing products must be labeled with the following disclaimers:

• "High caffeine content. Not recommended for children or pregnant or breast-feeding women". The label applies to beverages other than tea or coffee that contain more than 150 mg/l of caffeine.

• "Contains caffeine. Not recommended for children or pregnant women". The label applies to food and supplements where caffeine is added for a physiological purpose.

The caffeine content of applicable products needs to be expressed on the label in mg per 100 g/ml, or per portion in the case of supplements.
