Measuring your sports drink colours with a reliable spectrophotometer is the best way to determine whether your product has the right colour from batch to batch. Sports drinks are rich in colour and can contain several food dyes regulated by the Food and Drug Administration (FDA). Obtaining optimal colour stability while remaining FDA-compliant is critical.
How the Colour in Sports Drinks Is Measured
A spectrophotometer measures the colour of sports drinks and many other colour-infused liquids. The spectrophotometer measures the light absorption capacity of the colours present in your sample. It does this by measuring the colour at a particular wavelength to separate the white light into a rainbow of colours. The machine then passes this light through your test sample using diffraction gratings.
