XXXCJPUJVNaPN Spectrophotometric Determination of Dye Content in Beverages. Rebecca Nagurney and Jillian Grudzinski. Advisor: Dr. Pham. In this work we determined the amount of dyes in some commercial food products using spectrophotometric methods. We tested red and yellow Powerade drinks which according to the manufacturer contain red #40 and yellow #6 respectively. By applying Beer’s law, we found that the red Powerade contained 0.051 grams of dye and the yellow Powerade contained 0.059 grams of dye per bottle. These amounts may not seem like much; however, because most food products contain dyes the amount of dyes we consume in our diet per year could be rather large. An individual consuming one bottle of Powerade a day is consuming more than 18 g/yr. . Natural dyes. Text: Chapter 12 . pp. 400-405. Natural . fibers: cellulose. . (polysaccharides).

It is best if it has a high content of 100% cotton as cotton absorbs very well and so the dye will take and you will achieve a good result. Have a look around the house and see if you have any old white shirts, t shirts, socks, pillow case that could be cut up and used for dyeing. You only need a piece approx. 15cm x 15cm. Read the method on the next slide so you can see what you will be doing..
