Analysis of Food Dyes in Sports Drinks

Students use a colorimeter to quantify the amount of food dye in a sports drink.

This lab is an introduction to spectroscopy. The correlation between absorbance and transmittance of color in food dyes is emphasized as is the use of the Beer-Lambert Law for quantitation of food dye content in sports drinks.

Featured Equipment

Colorimeter and Turbidity

Wireless Colorimeter & Turbidity Sensor

This sensor can function as a turbidimeter or colorimeter and is capable of measuring absorbance and transmittance at six different wavelengths.

Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. For assistance with substituting compatible instruments, contact PASCO Technical Support. We're here to help.
