Question

Exercises After comparing the 100% cranberry juice absorption spectrum to the 100% apple juice aborption spectrum, do you think that apple juice contributes to the color of cranberry-apple juice at the Amax you selected? Why or why not? 2. When you look at cranberry juice and at apple juice, the colors that you see are the parts of the visible spectrum that is not absorbed by the juices. When you look at the absorption spectra of cranberry juice and apple juice, what colors/parts of the visible spectrum are absorbed? Discuss how the colors/parts that are not absorbed contribute to the colors of cranberry juice and apple juice. 3. Cranberries contain the phytochemicals called anthocyanins. Using the internet, find four examples of other phytochemicals and where they can be found. Provide the information in table form.

Answer 1

1. The apple juice contributes to the color of cranberry-apple juice ant the lambda max I selected because it the absorption of apple juice is within the range of different concentration of cranberry juice.

2. In the absorption spectra of cranberry juice and cranberry-apple juice, the color of the visible spectrum that are absorbed are orange, yellow, green, indigo, blue and violet. These colors are absorbed but not reflected such as the color red, and cranberry juice is red.

also, Cranberry juice is red and red light is absorbed from 500-540nm. We observe red cranberry juice because only red light is transmitted and the rest of the spectrum is absorbed. Similarly, apple juice is yellow which is absorbed from 380-435nm. It appears yellow because only yellow light is transmitted through the solution and the rest of the color spectrum is absorbed.
