Students produce a chromatogram using the colour extracted from jelly babies in the practical experiment C2. This shows that food colours are often mixtures containing several different pigments.
Chromatography
How do you colour a jelly baby?
The manufacturers of jelly babies add colours to the sweets. In this investigation, students remove the colours from different jelly babies and use it to dye a piece of wool.
Looks good enough to eat
Food colourings are often added to make food look attractive and enhance its appeal. Students look at a range of food colourings and colours found in foods, such as beetroot and cabbage. The effects of pH on these coloured compounds are investigated.
