Colorimeter user Verity Cheslo has posted an experimental write-up on her research using the colorimeter to measure lycopene levels in varieties of tomatoes. Lycopene is the red pigment found in tomatoes and other fruits and vegetables. Researchers are particularly interested in lycopene for its nutritional and anti-oxidant properties. Verity used the colorimeter in a science project to measure absorbance of extracts from a variety of tomatoes, preparing extracts from the tomatoes at home using a blender and filters. Earlier this year, Verity presented her research and results as a poster, winning 1st place in not one but two science fairs including 1st place in the 9th & 10th grade biochemistry division at the Coriell Science Fair ! This Summer, Verity took the time to write-up her experimental procedure for measuring lycopene in tomatoes with the colorimeter and shared her results on the Wiki.
