Our project is about coloring agents in sweets. It consists of analysing the composition of coloring agents in sweets, the dangers and the diseases of coloring agents for human body.
We did experiments to discover what the coloring agent of the Smurf is. For this experiment we needed chemistry equipment (for example beaker, spectrophotometer, colorimeter...).
We made a Smurf solution to compare with other solutions of blue coloring agents in order to know what coloring agent is in the Smurf. When we find the good coloring agent ("blue Patenté V") we searched the concentration of coloring agent in one Smurf. For that, we made a scale of differents tints and we drew a curve of calibration to know the exact concentration.
