McCormack Food Dyes in cooking and for other applications. The Food and Drug Administration regulates the use of additives to our food supply. The following food dyes are approved for consumption by the FDA: Red–40, Red–3, Blue–1, Blue–2, Yellow–5 and Yellow–6. Paper Chromatography can be used to separate these components within a specific dye. This technique can be applied to analyze the composition unknown dye samples. In today’s workshop, we will practice the procedure on standard dyes, and then analyze unknowns.

We will be meeting in UBC 152 (Chemistry Lab).
