Gallic Acid is a polyphenol produced by plants, which shows antioxidant properties. It is commonly used to measure polyphenol concentration but could also be used to measure antioxidant capacity. It is present in a wide variety of plant-based food samples.

Use this standard with colorimetric assay kits or to compare the BQC electrochemical devices results (µC) to classical antioxidant capacity units of Gallic Acid.

• When the Gallic Acid is order for the BRS in agri-food samples, BRS electrolyte is included to perform the calibration curve.
• When the Gallic Acid is order for the BRS in biomedical samples, PB (phosphate buffer) is included to perform the calibration curve.
