Phytosterols in food


Plant sterols and plant stanols, known commonly as phytosterols, are plant-derived compounds that are structurally related to cholesterol. Important food sources of phytosterols include unrefined vegetable oils, whole grains, nuts, seeds, and legumes. Sterols can be electrochemically detected without derivatisation, on boron-doped diamond (BDD) electrodes at high potentials. This note shows the proof of principle for the fast and sensitive analysis of Phytosterols using the ALEXYS Analyzer.

System configuration

For the analysis of phytosterols in food products we use the ALEXYS Analyzer. For best sensitivity the DECADE Elite is equipped with a FlexCell in combination with a Boron-Doped Diamond (BDD, Magic Diamond) working electrode vs. HyREF (Pd/H2).
